Yet another company has made news this week for phase 2 trial progress. Concert Pharmaceuticals announced today that they have completed enrollment for their phase 2a trial using CTP-543 in alopecia areata. CTP-543 is an oral JAK inhibitor which acts on JAK 1 and 2, it’s also known as ruxolitinib. Concert’s version of ruxolitinib has been modified by the company’s proprietary deuterium chemistry technology which the company hopes will improve its effects on AA.

We know our products deliver the intended results for the overwhelming majority of men and women who use them as directed. How do we know this? Because we have witnessed the results first-hand on customers of every age, race, and hair type. Because we've spent over 10 years developing, evolving and continually perfecting functional hair care products just like this. Because the Veta product line was tested, piloted and proven at select A-list salons prior to being launched to the public.
The best shampoos for thinning hair are the ones that address more than just flat hair, so when shopping for a shampoo, look for lightweight, nutrient-rich formulas designed to aid in proper hair production and health, while also providing a volumizing effect. Luckily for you, we already did the hard part for you and scoured the beauty world for the best picks for every hair type. 
Hair spa. A hair spa treatment is one of the most convenient, non-invasive, not to mention, most rejuvenating ways to treat hair loss and promote healthy hair growth. Besides hair loss, it has also been known to address other hair issues like dandruff, split ends, and dry and damaged hair. There are many forms of hair spa treatment depending on what's offered at the salon, but it generally includes an oil massage of the scalp, shampoo and deep conditioning. The whole process helps in blood circulation, bringing the needed nutrients to the follicles, and activates the glands to produce oil.
Again, you’ll want to visit your doctor to get a blood test to check your levels in these vitamins. For example, women who have iron levels lower than 70 nanograms per milliliter are considered deficient. From there, work with your doctor to find an appropriate dose according to your deficiency level. Excessive or unnecessary supplementation can be dangerous.
Finasteride inhibits an enzyme that converts testosterone to DHT, or dihydrotestosterone, the hormone that causes hair loss in men, and unlike minoxidil, this drug can actually help hair grow back, as well as prevent further loss. All you have to do is take one pill a day, and according to Dr. Evan Rieder, dermatologist in the Ronald O. Perelman Department of Dermatology at NYU Langone Health, two-thirds of men taking this treatment will see improvements in hair density over time.
While it’s not entirely clear why hair growth occurred after taking dupilumab, Senna hypothesizes that dupilumab may alter the immune system pathway that is overactive in eczema sufferers. "Right now, it's hard to know whether dupilumab could induce hair growth in other alopecia patients, but I suspect it may be helpful in patients with extensive active eczema and active alopecia areata," she explained.
A bathroom covered with loose strands or an ever-scrawnier ponytail can be startling but doesn't necessarily mean anything's wrong. By age 50, half of women will complain of hair loss. "As we age, overall hair density changes and individual strands become finer," says dermatologist Doris J. Day, MD. But just because thinning is natural doesn't mean you have to accept it. Here are 13 solutions to help you keep the hair out of your brush and on your head.
This shampoo has one of the top ratings of any shampoo sold online. KIMI Naturals must be doing something right! Saw palmetto, biotin, argan oil, and keratin are some of the highlight ingredients in this shampoo. They offer a 60 day money back guarantee, so if you’re not happy with the results after you give it a go, get you’re money back. On their KIMI Naturals website, they also sell a vitamin supplement and scalp treatment which they sell together with this shampoo as a 3-pack system.

There’s also a women’s version (Women’s Rogaine Foam) — but a three-month supply costs $22 more online. The only difference between the two products are the instructions; women are instructed to apply once a day instead of twice. If you’re a woman who doesn’t feel like paying extra for marketing, the men’s product will suffice. A cheaper generic version is Kirkland Signature Minoxidil Foam, but with a longer history on the market and more customer testimonials, Rogaine is our first choice.

That meant new products like Hims and Keeps were out.Hims and Keeps are relatively new companies that allow you to set up a subscription for hair loss treatments. Both offer finasteride (after an online consultation with a doctor) or 5 percent minoxidil. However, their minoxidil solutions contain propylene glycol, so we cut them from consideration.

If you do decide to start treatment to save your hair, a good place to start is with minoxidil, more commonly known as Rogaine. Don’t expect this hair-loss treatment to create luscious locks; minoxidil is better at slowing down or preventing more loss rather than promoting hair growth. But, according to Dr. Amy McMichael, professor and chair of Wake Forest Baptist Medical Center’s Department of Dermatology, it is effective “if used as recommended, with evidence of improvement seen around six to nine months.” Simply massage the foam or solution into your scalp once or twice daily, and for best results, use a formula with 5 percent concentration.
An extremely popular organic product. There is significant evidence that biotin aids hair quality, while caffeine and saw palmetto are both somewhat beneficial to hair growth. Saw palmetto blocks the formation of dihydrotestosterone (DHT) and is often described as a natural (but weaker) alternative to finasteride. For more, see my post on natural cures for hair loss. This Botanical Green Care shampoo product also contains numerous other helpful ingredients such as nettle extract, panax ginseng, pumpkin seed oil, amla oil, bhringraj oil,  niacin, vitamin A, vitamin E (alpha tocopherol) and more.

Regarding the RCH news, is your source more reliable than Lee Buckler since he seems to know more about RCH than Lee buckler himself. Recently, Lee Buckler tweeted “We anticipate seeing data from the RCH-01 study in Japan sometime before year-end but the real answer is whenever the investigators/hospitals in charge of the trial (not us) decide to release the data once it ready”


However, each formula contains a different mix of ingredients and will act on preventing the hair loss process in a unique way. Perhaps one of the best things about these anti DHT shampoos is that they are mostly natural and organic compositions with little to no side effects. Probably your biggest risk in using one of these shampoos is a red or itchy scalp, which typically goes away after a couple hours following your shower.
And, for all of these collective efforts, Christiano reminded me, the only things that have really worked were discovered accidentally. Soon to join minoxidil and finasteride will be Xeljanz, or tofacitinib: originally developed for rheumatoid arthritis, it has remarkable effects on hair growth for patients with alopecia areata, an autoimmune disorder that causes patients to lose hair in big patches over their entire bodies.
The Rogaine rep we spoke to explained that the different packaging (and therefore different prices) has to do with the FDA-approval process: “We discovered in clinical trials that the hair loss patterns between men and women are different,” she said by way of explanation. “Men typically have that bald spot on the crown of their head, where women generally have a general thinning throughout, but concentrated more on the top of the head. So for FDA approval, we had to come up with two different, gender-specific products, so the directions were more explanatory.”
Protein: When the body does not get enough protein, it rations the protein it does get. One way the body can ration protein is to shut down hair growth. About 2 to 3 months after a person does not eat enough protein, you can see the hair loss. Eating more protein will stop the hair loss. Meats, eggs, and fish are good sources of protein. Vegetarians can get more protein by adding nuts, seeds, and beans to their diet.
A few studies support the use of red ginseng, sometimes called panax ginseng (about $25), for hair regrowth. It can have an anti-apoptotic effect on the hair, Rogers says, meaning it slows cell death so hair follicles can grow for a longer period of time. But before taking any of these supplements, it’s important to consult your doctor; a lab test can confirm whether you need a particular supplement or if taking it will just be a waste of time and money.
But there is a Canadian company who has been working diligently to change that. And if they’re right—and so far the research indicates they are—baldness may become a thing of the past for those who choose not to tolerate hair loss anymore. And they're not only attacking baldness, Aging skin and tendon degeneration are on the cutting block as well. It's great news for the tens of millions of older Americans who suffer from these malladies. But the most fascinating part lies in the source of the cure. It’s you. The company focuses on the development of cell therapies using a patient's own cells.

Our specially formulated natural remedy for hair loss and shedding is made with natural ingredients. We use high quality products, such as D Panthenol, tea tree oil and evening primrose, to nourish the scalp. This eliminates current hair loss and prevents future problems. It targets the root of falling hair, and penetrates the scalp and hair follicles for itch free, flake free skin that is nourished and ultra hydrated. Our formula rejuvenates and regenerates skin and hair follicles for revitalized, beautiful hair.
It is called the vampire treatment because blood is taken from the patient that removes the platelet rich plasma. Then, the PRP is injected back into the scalp. This energizes the scalp with new active blood flow. Treatment is available at select clinics but widespread adoption may become the norm. It is less invasive than hair transplants but costs more if you count the cost of doing many sessions.
We know our products deliver the intended results for the overwhelming majority of men and women who use them as directed. How do we know this? Because we have witnessed the results first-hand on customers of every age, race, and hair type.

A diet that is poor or lacking in certain nutrients, particularly iron, protein, and vitamin B, which are essential in the production of keratin, can cause a long telogen phase and a very short anagen stage. On the other hand, excess supply of vitamin A in the body, especially those taken through supplements, can prove to be toxic and can cause a range of adverse body effects including loss of appetite, fatigue and consequently, hair loss.

Thanks so much for the guidance! After further research I have to agree with you 100%. Lipogaine Big 3 does containe ketoconazole, which would eliminate the need for Nizoral, however the shampoo only contains a few hair loss/thinning related ingredients. The Big 5 contains 17 and just seems like a better overall product. That plus Nizoral twice weekly seems pretty solid to me. 

Certainly a company with a unique background and game plan, HairClone has received some recent media attention. The UK biotech startup was featured in this month’s publication of “Consulting Room” online magazine. In the article both Dr. Bessam Farjo and Paul Kemp of HairClone provided insight as to the company’s current progress and plans for the future. Things seem to be coming along well for HairClone and we should expect to hear from them again within the next several weeks. Full story is on Articles main page.
Follica is developing a wounding device that when coupled with a hair stimulant like minoxidil, is found to be more effective at triggering new growth. They like to call this wounding process ‘skin disruption’. The idea behind this treatment is that after the skin is wounded, cells migrate to that area to repair. They then must choose between two paths: healing the skin (making epidermis) or making hair. It is there where Follica sees the window of opportunity, where they can encourage the cells to do the latter and regenerate new and more hair.

In our research and our conversations with experts, one name kept popping up repeatedly: Rogaine. As the first topical brand FDA-approved to help regrow hair (all the way back in 1988), Rogaine benefits from more than 20 years of clinical trials and consumer feedback. Rogaine was the first brand to offer a 5 percent minoxidil foam solution when it debuted Men’s Rogaine Unscented Foam in 2006, and virtually every treatment developed since (for both men and women) has been an imitation or derivation of that formula.


It can be safe provided you use registered, regulated healthcare or pharmaceutical services. LloydsPharmacy Online Doctor offers both Propecia and finasteride for men suffering from male pattern baldness through a safe and discreet online prescription service, and you will be able to order minoxidil or Regaine through our online shop or in one of our pharmacy stores.
There have also been studies on the effects of 1% pyrithione zinc shampoo and a 5% minoxidil solution. In one study, 200 men between the ages of 18 to 49 who experienced baldness between type III and type IV on the Norwood scale were given this treatment for a six-month period. They found that minoxidil, when used on its own, was approximately twice as powerful as pyrithione zinc at stimulating hair growth, but that both products were successful at increasing the amount of visible hair when used over a 26-week period.
This video is equally hilarious. Once again, there is inspiration here. Deion had a 5,000+ FUE last year and received good results from it. But he’s not done yet, he has the resources to have another procedure and get as close as he can to the result that he really wants, so he did. Surely, he’s just about maxing-out his donor area now. Once again, congratulations to Deion for pursuing his hair growth goals. Enjoy the video and have a big laugh. OOOOeeee.
RepliCel is a form of cell therapy that has a lot of folks excited. This is also known as RCH-01 and RepliCel is collaborating with global cosmetic company Shiseido. RepliCel will be an injectable like Histogen or Botox for example. It is basically hair transplants on steroids, but they are migrating cells instead of hairs. Their goal is to take a seed biopsy then multiply it in the lab for about 3 months. After replication, they inject it back into the scalp where it is needed. RepliCel has completed a phase 1 clinical trial and will enroll 160 male participants with mild to moderate hair loss for their Phase 2 trial. In other news RepliCel announced a research collaboration with University of British Columbia. They goal is to create a map with protein and gene expression of hair follicle cells to help RepliCel further improve their cell therapies i.e. hair loss prevention products.
I started combining two of them right away – because they both had different ingredients that I really wanted. I combine the Hair Surge for the caffeine, ketoconazole, and saw palmetto, along with the Regenepure DR for the Emu oil. I use a bit of both every day – and though I haven’t noticed a lot of hair coming back in – I HAVE noticed that a whole lot less is falling out. I used to see lots of hair in the tub or in my hand after drying. Hopefully some baby hairs will start so show themselves soon.
This moisturizing double-duty product is incredibly well rated (and you don’t even have to pay the pink tax to boot). Soy proteins and shea butter add silky strength, while scalp-tingling peppermint and rosemary provide minty freshness and lift at the root. “The thickening properties of the shampoo are great at this price point, so if you have thin or thinning hair, this will add some volume,” wrote one reviewer. “I also noticed that this is the first shampoo/conditioner shampoo that tends to actually condition your hair."

Many pharmaceutical companies and researchers are in the search for a hair loss cure. This is because 7 out of 10 men and 4 out of 10 women suffer from androgenic alopecia (genetically caused hair loss) in their lifetime. In the United States that amounts to around 80 million men and 40 million women currently suffering from hair loss. Of course, a permanent cure would relieve a huge percentage of the population.
Late last week, HairClone officially unveiled its crowdfunding campaign with the Euro-based crowdfunding company Capital Cell. HairClone is offering equity based crowdfunding, which means anyone who makes an investment (£500 minimum) owns equity in the HairClone company. Full details on the campaign are listed in the latest HairClone article on the main page of Follicle Thought.

Joseph and his readership, he said, are convinced that we are at a “peak moment” for the industry. He ticked off “platelet-rich plasma” and “injectable cell therapies” and other high-level technologies that are being developed by companies from New York to San Diego, Tokyo, and Stockholm. He won’t make bets on who’s going to win the arms race. But, he says, “if you were the first, that’d be fun for the trillion dollars that you’d make. Over the next few years? It’s prime time.”

While thin hair is nothing to be ashamed of, it's perfectly natural to look for a way to maintain the luscious locks you know and love — and the easiest way to do that is by incorporating the best shampoos for thinning hair into your beauty routine. Whether it's due to stress, hormonal changes, or simply aging, thinning hair and hair loss is something we as women all face at one point or another during our lifetimes. But before we talk about a treatment, let's break down some of the possible reasons behind your thinning hair.
A substance produced by bees, Propolis was found to help hair growth in mice. A group of scientists from Hokkaido University in Japan caused a good deal of hype in hair loss circles following their discovery. However, it appears that this may only cure hair loss that is a result of inflammation such as alopecia areata. Little is known about its benefits for treatment of androgentic alopecia.

How about if you’d rather not get your head punctured? In Sweden, a company called Follicum is now doing Phase IIA clinical studies and planning to communicate results by the end of the year. The end product will be a cream or a lotion, one that could be applied as few as three times a week. In the first trial, Follicum claims, more than seventy-five per cent of patients experienced hair growth. This is the real dream, the one so artfully captured in the Hims ads: pop a pill, slap on some cream, and get Hair God locks.
I am extremely pleased with this shampoo product. I have hypothyroidism and my hair has been falling out in clumps for a few years. I purchased this shampoo and used it for 4 months before posting my review. I have tried several other brands of hair loss treatment shampoo's(Pura'dor/Nioxin/Renpure) Nothing worked. The other shampoo's seemed to make my scalp tingle and itch from dry scalp. While Biotin shampoo has not fully stopped my hair from falling out, it has helped decrease the hair loss, itching, and dry scalp. It took a good 2 months before I started to notice a decrease of hair loss. During this 4th month of using the shampoo I, also, added a Biotin Vitamin and Osteo Bi-Flex Nutrajoint Glucosamine Joint & Immune Support Formula supplement. These 3 together have greatly reduced my hair loss, even more, during this 4th month. I used to have to vacuum my bedroom and home office space daily because I couldn't see the carpet through the thick wads of hair. I no longer have to vacuum daily. I'm vacuuming once a week. I highly recommend this shampoo. And pair it with a biotin supplement to increase benefits.

Due to the concern of several readers, I’ve removed the link to the new Trinov website that has popped up on the net. For now, the website only contains an email address subscription box which really poses no issue to anyone who subscribed. At this time, it’s not confirmed who the actual owner of the new Trinov site is, so use your discretion until we find out more regarding this matter. Until more information is known the website will not be shared on Follicle Thought.
A DHT Blocker Shampoo is any shampoo formula that contains known DHT inhibiting agents. DHT inhibiting agents usually act by preventing 5 alpha reductase from converting testosterone to dihydrotestosterone (DHT). Leading research agrees that DHT is the foremost cause of hair loss. DHT binds to sensitive hair follicles causing them to shrink and eventually to stop producing hair altogether.

The cause of female-pattern hair loss is unknown, but doctors said there is a strong genetic component. The risk can come from male or female relatives. Though it looks as if the hair is falling out, that's not really what's happening. Cotsarelis said hair follicles are becoming smaller and producing hairs that may be so small that you can't see them.  Women tend to retain more normal, thick hairs than balding men do.
This particular research which was published in the Nature journal showed that a synthetic version of sandalwood, called Sandalore, binds to the OR2AT4 receptor in hair folliles and prolongs their anagen (growth) phase. The hair follicles studied were treated in a petri dish. Paus has subsequently announced that a completed clinical trial of 20 female volunteers using a topical version of Sandalore showed a reduction of daily hair loss. There is also another larger clinical trial ongoing now which hopes to confirm the effect and announce results in early 2019. Paus has gone as far to say “there is even a chance that this might be able to bring the hair back.” We’ll keep our fingers crossed.

"Firstly, even the very good ones won’t get to the root of the issue - pardon the pun - and prevent or treat male or female pattern baldness which is caused by genetics, nor deal with hormonal issues at the heart of female hair loss. But they can help make the hair you do have stronger and healthier. And they can be useful in putting a hair loss regime in place, along with medication like Minoxidil or Finasteride and/ or a hair transplant.
“It all started with a particular drug, Cyclosporine A, which is an immunosuppressant,” Hawkshaw explains. “It’s typically given to transplant patients to stop them rejecting new organs post-surgery and it’s been observed that it enhances hair growth. But the thing is, you don’t really want to give this to patients normally because you don’t want to suppress their immune system. So, I used that drug to treat human hair follicles in the lab to try and identify how it actually worked.”
In fact, research posted in the Journal of Dermatology found that ketoconazole was effective in treating mice for dermatitis and hair loss. In clinical trials, researchers found that 15 men who used finasteride, minoxidil, and ketoconazole for a 90-day period benefitted from hair growth, getting a noticeably thicker head of hair than what they had at the beginning of the studies.
I am a 45 yr female that has experienced hair loss to the point of having to hire a plumber twice (over 3 years) to unclog our drain in our main bathroom although I am pretty cautious about picking up my hair. My ponytail is about 1/2 the size that it was 5 years ago. i had excessive hair loss after the birth of my last 2 of 3 children. It is noticeably thinner although my employees, friends and husband seem to think my hair is thick. I can see my scalp very easily. (No patchy alopecia though) I started using viviascal professional strength about 2 months ago and hair surge shampoo only about 2 weeks ago. The bottle has about 1/3 left and i am wondering what is to be expected from this product. I have to use at least 8 pumps ( it seems to be double the volume of normal shampoo that i use) and it does not seem to later that well until after a min or so. Additonally i am using the hair surge supplement. When should i see less hair falling out? When should i expect visible results. Any other suggestions? I know it says to use 5 of 7 days, but i use it daily to make sure i am getting the full benefit ( if any) from this product. Currently i am looking at 100 buck a month for the shampoo alone if i keep this up. Any advice is welcome. Thanks
In fact, the Japanese government has recently committed to establish a new approval process for regenerative medicine products focused on accelerating approval timelines. As it turns out, hair loss is a big concern in Asian countries. Buckler said some 21% of adult males and 6% of females in China suffer from hormone-driven hair loss.  And the International Society of Hair Restoration Surgery’s (ISHRS) biennial survey of hair restoration physicians found that the number of hair restoration patients in Asia increased 345% from 2004 to 2010.

There are a lot of reasons why your hair may be falling out. It could be hereditary (which you unfortunately can't control), or linked to health- or diet-related changes. Or it could be as simple as the fact that your scalp is stressed by excess buildup—oil, dandruff, multiple days' worth of dry shampoo—that's preventing new hair from growing. Or your strands are (literally) at the breaking point after daily sessions with the flat iron.


A study led by Dr. Noha Doghaim of Tanta University in Egypt showed that carboxytherapy may be a promising treatment option for both alopecia areata and androgenic alopecia. The study comprised 80 subjects who were treated over the period of three months with either placebo or carboxytherapy.  Both groups found favorable results from the carboxytherapy, however during a follow-up examination the improvements in androgenic alopecia subjects had decreased over time. The researchers noted that continual treatments would be necessary to maintain and bolster the benefits for AGA.
Lee Buckler, CEO of Replicel, stated in an interview this week that he expects Shiseido to release clinical trial results in 2018. This is great news that everything is still on track for the anticipated 2018 release of Replicel’s RCH-01 technology in Japan. Lee mentioned “It’s entirely up to Shiseido what they do in regards to this product. There’s certainly a possibility that they could decide if the data is positive, to launch the product in Japan…”. Yes, it seems likely that if the data is positive, Shiseido would go to market with one of the biggest technological breakthroughs of the century. Full interview here. 
We’re not exactly sure about that “growth potential” stuff; for our purposes, the question is whether the product works to stop hair loss. Several of the confusing phrases the company uses actually address that question. The shampoo works to protect mitochondrial DNA, an important component in protecting and growing hair follicles, with fatty acids. It also contains ingredients which prevent further damage to the follicles. In other words, it protects and strengthens the hair you already have.
However, each formula contains a different mix of ingredients and will act on preventing the hair loss process in a unique way. Perhaps one of the best things about these anti DHT shampoos is that they are mostly natural and organic compositions with little to no side effects. Probably your biggest risk in using one of these shampoos is a red or itchy scalp, which typically goes away after a couple hours following your shower.
However, this partnership ended in 2007 due to potential safety issues since SHH can potentially also cause basal cell carcinoma cancer. P&G was not willing to continue with the drug development work, since even a very minimal risk of developing cancer is not worth it for treating a cosmetic problem such as hair loss (at least in the eyes of government). Interesting comment from the at-the-time CEO of Curis:

What's to know about alopecia areata? Alopecia areata is an autoimmune disorder that usually results in unpredictable, patchy hair loss. Approximately 7 million people in the U.S. have alopecia areata, and it can affect anyone of any age or gender. There is no cure for alopecia areata although some treatments are available to help hair regrow more quickly. Read now 

During this procedure, surgeons remove a narrow strip of scalp and divide it into hundreds of tiny grafts, each containing just a few hairs. Each graft is planted in a slit in the scalp created by a blade or needle in the area of missing hair. Hair grows naturally this way, in small clusters of one to four follicles, called follicular units. As a result, the graft looks better than the larger "plugs" associated with hair transplants of yesteryear.
