There’s no getting around it – it’s depressing when you first realize that you’re starting to lose your hair. Other signs of natural aging can be hidden or explained away, but thinning or disappearing hair is different. Your hair is not only front-and-center whenever you’re in public, but it’s one of the features which define you through most of your life. To many, hair loss is a traumatic experience which can seem impossible to deal with, let alone overcome.
Pfizer Reports Positive AA Trial Results – A JAK3 inhibitor and a tyrosine kinase inhibitor (TYK2/JAK1) have shown statistically significant results in a phase 2a trial conducted by Pfizer. The company announced the results on September 15, 2018 at the European Academy of Dermatology and Venerology Congress. Subjects of the trial received oral doses of the drugs over a 6 month period. The TYK2/JAK1 inhibitor showed the greater efficacy, improving hair regrowth by 49.5 points on the Severity of Alopecia Tool scale, compared to an improvement of 33.6 points by the JAK3 inhibitor. However, Pfizer has apparently decided to move forward with its JAK3 inhibitor due to 2 adverse events in the TYK2/JAK1 inhibitor cohort during the trial. Pfizer’s JAK3 candidate, PF-06651600, was also recently granted Breakthrough Designation from the US FDA for treating alopecia areata. 

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.


As I entered a small operating room at Bernstein’s Midtown East medical practice, a front-desk secretary shouted out, “Hope you got a strong stomach!” Inside, a patient dozed in an operating chair, while nurses held a strip of back-of-the-head skin—something like a fat hairy caterpillar—with tweezers. They began dissecting the follicular units under a microscope.
A separate study, published in Skin Therapy Letter — a professional reference site for dermatologists — found that women also benefit from using the more potent 5 percent minoxidil treatment. “Patient-reported improvement in hair volume and coverage appears to be greater with 5 percent minoxidil foam,” reads the report. Plus, because the 5 percent treatment is stronger, women only have to apply it once a day to get the same results as they would with the 2 percent treatment applied twice daily. 

Natural hair that is subjected to constant physical trauma from excessive brushing or combing, tight braids or ponytails, or extreme scratching or massage can cause hair at the temples to become weak and to stop growing to its normal length. Clean shaving, especially for men, can cause white bumps to appear on the area where the hair was shaved short, and at times can become infected with pus and leave permanent scarring, affecting hair growth.
This medication goes by the name Avodart. It is used for the treatment of BPH also known as enlarged prostate. However, there are a large number of users using it for the off label purpose of treating hair loss. Remember the 5 alpha reductase we mentioned that Propecia blocks? Well there are two types of 5 alpha reductase. Type I and Type II. Whereas Propecia has only been shown to block type II, Avodart blocks both types. This effect overall lowers DHT levels even more, further reducing the risk of damaged hair follicles. However, it faces the same limitations as Propecia. It must be taken daily and may lose its effectiveness overtime.
Hair changes about as fast as grass grows, which is to say it’s extraordinarily slow and not visible to anyone checking impatiently in the mirror every day. But during regular follow-up appointments, Harklinikken uses high-tech equipment to photograph and magnify the scalp and count new hairs and active follicles, which motivates users to adhere to the regimen. Too many people give up on treatments like Rogaine and low-level-light devices before they’ve had a chance to work, Dr. Senna said.
A popular skin care drug—which is intended to target eczema—was just found to have an unusual side effect: hair growth. According to an article on Newsweek, the FDA-approved drug dupilumab was given to a 13-year-old alopecia sufferer to treat her eczema. The patient, who hadn’t grown hair on her scalp since she was two, suddenly grew a significant amount of hair on her head after continual use of the drug, a study in the journal JAMA Dermatology reports.
A more temporary form of hair loss is telogen effluvium or when hair follicles get stuck in the telogen or resting phase and stop growing new hair. Telogen effluvium can occur three months after a significant medical event like childbirth, surgery, or a high fever, but can also be caused by a thyroid imbalance or iron deficiency. Certain medications like blood thinners and birth control pills are also linked to this form of hair loss.
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.

Key features: Dr. Zeichner recommends the Keratin Oil Shampoo and Conditioner by OGX for thinning or fine hair that needs the extra strength. This budget-friendly option uses keratin proteins mixed with argan oil to nourish, condition, and strengthen strands, and it's only $16 for the set. The smoothing formula can also increase elasticity for less breakage and split ends.
Contact immunotherapy. Another drug that can be administered for cases of alopecia areata is contact immunotherapy and is recommended for severe cases. Diphenylcyclopropenon (DPCP) is applied on the scalp every week, and the dosage of the drug is increased over time until a mild allergic reaction is observed, which signals that the drug is taking effect. Regrowth may be observed within three months from the beginning of treatment.
“Re the post 10/17/18 I really liked your response to the request made by one of your readers to email companies asking for information. So I decided to do what you suggested and sent emails to Organ Technologies, Rivertown and Follicum (no particular reason) basically thanking them for their work and wishing them success with their products. Interestingly I received a very nice response from Organ Technologies which really surprised me. Correct me if I’m wrong but I think the sentiment is to be thankful and encouraging to what is being done appose to being negative that we have yet to get what we all want.”
Over the past year, the Hair Restoration Laboratories’ Professional Strength DHT Blocking Hair Loss Shampoo (and accompanying DHT Blocking Hair Loss Conditioner) has been a top seller on Amazon and many other sites. Combined, the daily use Shampoo and Conditioner has more DHT blockers than any shampoo/conditioner set presently available. Among the key DHT Blockers in this set are: Caffeine, Saw Palmetto, Black Cumin Seed Oil, Cayenne Fruit Extract, Rosemary Leaf Oil, Pumpkin Seed Oil, Green Tea Leaf Extract, Pea Extract and many more. By helping to block DHT, they should be a great asset in helping to halt the miniaturization of the hair follicles and regrow healthier and thicker hair.
And just like that, more fascinating hair-related research was published in PLOS Biology. A team of researchers lead by Dr. Nathan Hawkshaw of the University of Manchester have identified the drug ‘WAY-316606’ as a potential candidate for hair regrowth. WAY-316606 is an existing drug used to treat osteoporosis. It’s not clear at this time whether WAY-316606 is approved and on the market, or if it was partially developed to treat the bone disease.
In 2013, RepliCel began working with the Tokyo-based Shiseido Company, Limited—a Japanese multinational skin care, hair care, cosmetics and fragrance producer—on a collaboration giving Shiseido an exclusive geographic license to use RepliCel’s RCH-01 hair regeneration technology in Japan, China, South Korea, Taiwan and the ASEAN countries representing a population of approximately 2.1 billion people. “Shiseido and RepliCel will collaborate on the continued improvement of the technology and will conduct human clinical trials in each of their territories with the goal of commercializing a safe and effective hair regenerative treatment to help those suffering from pattern baldness and thinning hair,” Buckler said.

I also reached out to Histogen and Follicum a few weeks ago as well thanking them for all their hard work in bringing a safe and effective treatment to people all over the globe with hairloss issues and expressed how much we all value these companies. I held back from asking about market release as you had suggested. I received a very nice reply from Histogen.


After the new article featuring Medipost’s hair growth cosmetic was published, Jay Lee PhD of Medipost, began chiming in on the comments section. He first shared that Medipost is currently engaging in a larger clinical trial for the CM3 product which would include higher scale Norwood’s. Then, in a following comment he revealed that Medipost is developing a potentially more advanced hair growth product as well. Here are his words:
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.
The law enhances the FDA’s ability to modernize clinical trial designs and clinical outcome assessments, which will perhaps speed the development and review of novel medical products, including medical countermeasures. The Cures Act also directs the FDA to create so-called “intercenter institutes” to help coordinate  activities in major disease areas between the drug, biologics and device centers and improves the regulation of combination products. An example of one of these centers is the Oncology Center of Excellence.
It's for this reason that grocery stores have shelves stocked full with hair care and hair grooming products of all forms and kinds, for different purposes, and even specialized and customized for use of men and women. In one study, it was found that more than half of the men in the UK use about six to ten hair grooming products alone, from the staple shampoos and conditioners to hair gels and other styling products.
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.

Scientists from the Indiana University School of Medicine have for the first time created skin with hair follicles using mice stem cells. Research was led by Professor Karl Koehler. The team was able to grow both the epidermis and dermis layers of skin to create a realistic skin model. An interesting quote from Professor Koehler: “It looks like a little ball of pocket lint that floats around in the culture medium. The skin develops as a spherical cyst and then the hair follicles grow outward in all directions – like dandelion seeds.”
The most notable ingredients of the Big 3 are Biotin (vitamin B7), castor oil, and Emu oil. The latter helps defend against a variety of scalp and skin issues, including inflammation and allergic reactions. It also moisturizes the skin. While you could buy all three ingredients separately, it wouldn’t be very cost effective and why bother if you can purchase them in a product designed for hair loss?
Procerin Shampoo for hair loss is part of the Procerin For Men system. Recommended by many doctors and dermatologists it is available over-the-counter without a prescription. Procerin can help reverse hair loss in men suffering from Alopecia Areata and male pattern baldness.  >The Shampoo contains all-natural, powerful DHT blockers that have been tested. Procerin does not use any fillers, preservatives, artificial ingredients or additives. No dangerous or harmful side effects have been reported.  When combined with Procerin Supplement it is our best shampoo for men.
When it comes to organic products there are popular and high-quality brands you can choose from. Some chemicals can have quite harsh effects on longer hair, which means that they are not always suitable for women.  There are several organic brands that can be effective for those sensitive to these chemicals and in some cases can be more effective. Among the organic shampoos available are Reborn MAX and PhytoWorx.  Two brands that use caffeine are Apex Crown from Wick & Strom, and Ultrax Labs Hair Surge.
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.
If you’re a lady and can remember the one difference in directions (or just scope out the instructions online) we recommend saving the cash. Similarly, you could go generic with Equate Hair Regrowth Treatment for Men or Costco’s Kirkland Signature Hair Regrowth Treatment Minoxidil Foam for Men. These alternatives offer the same percentage of active minoxidil and near-identical inactive ingredients for as little as half the price — a great option for both genders.
The more upsetting problem is central centrifugal cicatricial alopecia, a type of baldness that starts at the crown of the head and spreads outward. "It's hugely, hugely difficult," said Susan Taylor, a dermatologist at Penn Medicine who specializes in treating women with CCCA. "It affects quality of life." She said it is seen "almost exclusively" in women of African descent. One study found it in 10 percent to 15 percent of black women, but Taylor thinks it's more common. "I could see women all day, every day, with this problem," she said.
“While nutritious eating isn’t going to bring your hair back by any means, eating plenty of protein-rich foods and healthy fats can make the hair that you still have look thicker and shinier.” Skimping on the B vitamins in particular can interfere with the formation of hair cells and, therefore, hair growth. The best sources of Bs are protein-packed foods like chicken, fish, eggs, and pork, as well as leafy greens such as spinach. (These foods are also good for melting belly fat, so it’s a win win).
I recently published an article covering a story in the press of SkinTE helping to possibly save the life of a burn patient (see Articles). In that post I shared an image from SkinTE’s website which shows an application for hair growth. What some may not be aware of is the fact that Dr. Denver Lough, CEO of PolarityTE, has done some legitimate hair follicle research while at Johns Hopkins University. Whether or not this will increase the chances of a “HairTE” product to become a success, we can’t say. However, it may be of interest to recall two peer reviewed articles that Lough and colleagues published involving the proteins LGR5+ and LGR6+ stem cells and hair growth.
Thyroid medication. Hair loss as a result of thyroid problems will only be solved by treating the root cause. This means that you need to take medications for hypothyroidism in order to address the hormonal imbalance in the body. The most common medication for thyroid problems is levothyroxine, a synthetic version of thyroxine (thyroid hormone). Since the medication is used to address the thyroid problem and hair loss indirectly, the medication has to be continued even when you've gotten better or your hormone level has gone back to normal in order to continue hair growth.
Hair is made up of the hair follicle (a pocket in the skin that anchors each hair) and the shaft (the visible fiber above the scalp). In the hair bulb, located at the base of the follicle, cells divide and grow to produce the hair shaft, which is made from a protein called keratin. Papilla that surround the bulb contain tiny blood vessels that nourish the hair follicles and deliver hormones to regulate the growth and structure of the hair.
4. Tinted dry shampoo. Camouflage spots where you’re seeing more scalp than you want to (your hairline, a widening part, a thinning crown) and add volume with a colored dry shampoo (try Orlando Pita Color Boost Dry Shampoo in Light or Dark Tones, $22). But be sure to give your scalp a vigorous shampoo during your next shower — dermatologists recommend keeping your scalp free of styling products so you’re not clogging already taxed pores.
DHT blockers and thickening agents combine forces to come to the rescue of hair follicle in dire straights. Good Lab packs this shampoo with just about every ingredient that has any clinical data whatsoever supporting it. Included is their hair boost blend, a patented combination of ingredients to help fight DHT. For it’s full effect, you might want to consider using this shampoo with the Good Lab conditioner and thickening serum.
Our other recommendation is the HairMax Ultima 12 LaserComb. The comb uses low-level lasers to stimulate hair follicles and modulate dihydrotestosterone (DHT) — a hormone that causes the most common type of hair loss. While it sounds like something from a sci-fi movie, the treatment works, and the dermatologists we consulted reported that their patients saw thicker and longer hair when combined with our top pick. The only catch: The comb isn’t as effective as minoxidil treatments, and at nearly $400, it’s a much bigger investment. Still, it’s the best option if you’re looking for a non-invasive, non-chemical treatment.
Dr. Hawkshaw and his team were lead to test WAY-316606 for hair growth after studying the effects of cyclosporine A (CsA) on hair growth. They found that CsA reduced the expression of SFRP1 in human hair follicles. After looking for other drug candidates that had a similar effect on SFRP1, WAY-316606 was identified. The team has already tested WAY-316606 on isolated human hair follicles which were donated from hair transplant surgeries, and plans to test the drug in human clinical trials in the future. A timeline for a human clinical trial has not been set yet, Follicle Thought will update this as news is presented.
Treatment for adults with less than 50% of scalp involvement is intralesional triamcinolone acetonide injected intradermally using a 0.5-inch, 30-gauge needle. Maximal volume is 3 mL per session.11 Treatment may be repeated every four to six weeks until resolution or for a maximum of six months. Local adverse effects include transient atrophy and telangiectasia.
Dr. Carlos Wesley, a hair restoration surgeon in Manhattan, said that women in his practice respond better to P.R.P. than men do, which may have something to do with the fact that women with genetic hair loss tend to have more inflammatory cells around the follicles. From 2013 to 2014, he said, he had an 83 percent increase in female patients, in part because of P.R.P.
There are pharmaceutical solutions, too. Finasteride (often referred to by its brand name, Propecia) and Minoxidil (aka Regaine/Rogaine) are both available via online prescription in the UK. They stop hair falling out as opposed to making it grow back again, though some report more lustrous locks after three months or so. Donald Trump is the world’s most famous Propecia user. “Never go bald,” he once counselled. “The worst thing a man can do is go bald.” He’s not wrong. The anti-bald dating prejudice that David lamented extends to politics. Only five US presidents have ever been bald. As laughable as Trump’s follicular arrangements are, chances are that if nature had taken its course, a bald Trump wouldn’t have got to the White House. Careful what you wish for.

"I could see women all day, every day, with this problem," she said.

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.


The main type of hair loss in women is the same as it is men. It's called androgenetic alopecia, or female (or male) pattern hair loss. In men, hair loss usually begins above the temples, and the receding hairline eventually forms a characteristic "M" shape; hair at the top of the head also thins, often progressing to baldness. In women, androgenetic alopecia begins with gradual thinning at the part line, followed by increasing diffuse hair loss radiating from the top of the head. A woman's hairline rarely recedes, and women rarely become bald.
Farrell makes what he calls “hair systems.” They’re not quite wigs or toupees—you can keep them on for weeks at a time. They cost more than a thousand dollars. Farrell was in New York for a week, holding meetings with clients in his hotel room. Now his rolling suitcases were packed. Malaysia, Singapore, South Africa, Russia: he’s almost always on the road, satiating international demand for high-end hair pieces.
Egg mask. Eggs are one of the riches sources of protein, which is the building block of keratin, as well as other minerals like zinc, iron, selenium, phosphorous and iodine. Mix an egg white with a tablespoon of olive oil and honey to make a paste. Apply it on your hair and leave on for 20 minutes. Rinse and shampoo using cold water. You can apply this egg mask on your hair once a week.
3. Hair fibers. The best (and easiest) way to hide a widening part or sparse patch is with hair fibers. They’re tiny, charged fibers that adhere to your scalp (until your next shampoo). Toppik Hair Building Fibers ($25) come in a range of colors so you can easily find one that matches your own hair. (In a pinch, you can also brush a powdered eye shadow that matches your hair color along your part.) 

If you’re looking for an au naturel option, look no further. This shampoo has been an Amazon best seller since 2012. It smells great, lathers well, and has no harsh chemicals mixed in. Pura d’or has elimated all the bad stuff from this shampoo—no Parabens or SLS. It does have a ton of good stuff too! Practically every clinically proven natural ingredient that aids against hair loss is packed into this shampoo. Nettles extract, he shou wu (fo-ti), argan oil, B vitamins, biotin, and saw palmetto.
While the drug is generally safe for use, some possible side effects are mild irritation of the scalp, dryness and growth of hair on some parts of the body, especially the sides of the face and hands. In some cases, you might observe some increased hair loss around the first few days of use. If the hair fall continues after two weeks upon application of minoxidil, stop the treatment first and see a doctor.

Anagen is the growth phase. This lasts for about 3 - 5 years, where you can observe your hair growing half an inch every month. Full-length hair from this phase is about 18 - 30 inches long. Studies show that this phase may also be affected by other factors. Asian hair, for example, has been found to have a longer anagen phase. Weather is also a factor; hair growth can be faster in summer than in winter.
McElwee is an associate professor in the Department of Dermatology and Skin Health at the University of British Columbia (UBC) in British Columbia, Canada and director of the Hair Research Laboratory in the Vancouver Coastal Health Research Institute (VCHI) at Vancouver General Hospital (VGH). A hair research scientist, McElwee is one of only a small group of research scientists worldwide who studies hair biology and associated diseases.
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.
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.

“People have been trying to sell a baldness cure since the beginning of civilization,” Kuntzman explained. “And the methods by which they try to sell that cure have not changed dramatically. These new companies, they’re trotting out the same promises that people trotted out in Roman times, when they said, ‘Use this hippopotamus fat to grow hair on your head!’ ”

For those of you who only check the Updates page, there was a new Brotzu Check-In article published yesterday. Giovanni Brotzu will be presenting data pertaining to his lotion’s use in androgenetic alopecia at an Italian hair research Congress this Saturday, April 14th. We hope to see photo results from the presentation. Check back to the Brotzu article next week for updates.

Argan oil is loaded with A, C and E vitamins, all of which have been linked to hair growth. When you use argan oil externally as part of a hair loss shampoo, it can help to boost your scalp’s and skin’s cell production, thus causing healthier hair and skin. Argan oil is good for dry, brittle and thinning hair since it guards against you losing more follicles than you’re capable of growing (which makes hair loss noticeable).

I am so happy with this product. I have thinning hair and have used many products in the past trying to at least stop it. I don't expect a miracle for it to grow back but I would love to just stop the hair falling out. Immediately after using this just one day I already noticed improvements. I was told my hair shined more, it was softer and also fuller. The hair falling out has improved a lot. I have not personally noticed hair growth yet but its only been 2 weeks now and I can say without a doubt it has made my hair healthier. I will be getting more for sure

You always hear these stories about people who take a homeopathic approach to fighting baldness. It’s always some off-the-wall remedy like smearing a paste of ginger and cayenne pepper on your scalp three times a day or eating a special type of ginseng farmed only in a rural village in Tibet. We'll go on the record to say that it's highly unlikely that these remedies work at any level.
A number of other shampoo and conditioner products are available that seem to be very popular with men and women suffering from thinning hair. These include a range of Shapiro MD and Nioxin hair loss shampoos. Also popular are Keranique and the uniquely named Bumble and Bumble thickening shampoo. Some of these do not have a sufficient number of reviews for me to consider adding them to my list of top shampoos.

Many other women, though, start noticing thinning hair on top of their heads. Doctors say the defining sign is a widening of the part. The hairline itself is usually intact, but the hair becomes less dense behind it. Doctors will often run a battery of tests to make sure there are no treatable medical conditions, such as anemia, thyroid problems, tumors, or hormonal problems. "Ninety percent of the time, it's normal," Patel said.
