As the name suggests, androgenetic alopecia involves the action of the hormones called androgens, which are essential for normal male sexual development and have other important functions in both sexes, including sex drive and regulation of hair growth. The condition may be inherited and involve several different genes. It can also result from an underlying endocrine condition, such as overproduction of androgen or an androgen-secreting tumor on the ovary, pituitary, or adrenal gland. In either case, the alopecia is likely related to increased androgen activity. But unlike androgenetic alopecia in men, in women the precise role of androgens is harder to determine. On the chance that an androgen-secreting tumor is involved, it's important to measure androgen levels in women with clear female pattern hair loss.

The dermatologist also will carefully look at your scalp and hair. During an exam, the dermatologist may pull on your hair. Sometimes a dermatologist needs to pull out a hair to get the necessary evidence. And sometimes a dermatologist needs to look at the hair on the rest of your body to see whether there is too little or too much hair in other areas.

Researchers from South Korea have identified a new peptide called PTD-DBM which exhibits wound healing and hair regeneration effects in preclinical studies. The research is being led by Professor Kang-Yell Choi of Yonsei University. Choi’s team identified the peptide PTD-DBM which targets a protein called CXXC5. The interaction of these two proteins leads to stimulation of the Wnt pathway, which then initiates hair follicle neogenesis. Choi hopes to develop this peptide further into a potential hair growth drug candidate. A research paper about these findings was put out by the team earlier this year. Source article about this development here.
While thinning generally worsens after menopause, doctors said hormone treatments typically do not improve hair growth. Minoxidil lotion or foam, which can be purchased over the counter, is the first line of treatment. About half of women who use it have not lost more hair a year later, Cotsarelis said. Spironolactone, a blood-pressure drug, can also help, doctors said. Some may also try finasteride — approved to treat baldness in men — off-label. The evidence that it works in women is weak, Patel said. 

Follicle Thought is interested in connecting with scientists and startups who are working on hair growth or hair loss prevention research. If you or a colleague is working on hair growth please get in touch on the Contact page, even if you are not ready to share news on the site yet. Follicle Thought can offer networking and other resources to benefit your development. Thanks

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.)


Some 30 million women in the United States have hereditary hair loss (compared with 50 million men), according to the American Academy of Dermatology, though that figure does not include the millions more who struggle with thinning hair because of pregnancy, menopause, stress and other health conditions. Barely 5 percent of women are said to be good candidates for hair transplant surgery because women lose hair everywhere, meaning that, unlike with men, there is rarely a luxuriant spot on the back of the head from which to harvest hairs unobtrusively.
Anagen effluvium is abnormal diffuse hair loss (usually abrupt) during the anagen phase due to an event that impairs the mitotic or metabolic activity of the hair follicle. The incidence of anagen effluvium after chemotherapy is approximately 65%24; it is most commonly associated with cyclophosphamide, nitrosoureas, and doxorubicin (Adriamycin). Other causative medications include tamoxifen, allopurinol, levodopa, bromocriptine (Parlodel), and toxins such as bismuth, arsenic, and gold. Other medical and inflammatory conditions, such as mycosis fungoides or pemphigus vulgaris, can lead to anagen effluvium.25

Indian gooseberry. Also known as amla, Indian gooseberry is one of the most popular natural ingredients that can induce fast hair growth. It is also a known antibacterial that can help maintain a healthy scalp. Mix a tablespoon of Indian gooseberry pulp and lemon juice. Use it to massage your scalp, and cover with a shower cap after. Leave on for the night and wash with shampoo in the morning. 

If you have something that works for you, don’t change. Search for products that have plenty of positive feedback and don’t just trust Amazon reviews, but dig deeper. Again, most shampoos that claim to halt hair loss and grow new hair are nothing more than snake oil. Stick with ingredients that are clinically proven to work and backed by scientific study.
I must have had about 5 readers email me today about the fascinating research coming out of Yokohama National University in Japan. Professor Junji Fukuda lead the efforts to successfully prepare “hair follicle germs” at large scale simultaneously. Essentially, the researchers prepared a cellular formulation with the right culturing materials to promote successful growth and development of tiny “hair follicle starter kits.” Source article here. 
If a pregnant woman comes in contact with crushed or broken Finasteride tablets, wash the contact area right away with soap and water. If a woman who is pregnant comes into contact with the active ingredient in Finasteride, a healthcare provider should be consulted. If a woman who is pregnant with a male baby swallows or comes in contact with the medicine in Finasteride, the male baby may be born with sex organs that are not normal.
Some factors that are thought to play a role in female hair loss include high androgen birth control pills, menopause, pregnancy, ovarian cysts, and other factors tied to the actions of hormones. The American Hair Loss Association said it’s important that women who have a history of hair loss in their family to be made aware of the potential effects of birth control pills on normal hair growth.
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.

Certain foods have also been found to aggravate or worsen hair fall, such as sugar, which triggers the overproduction of the male hormone, androgen, which in turn causes the hair follicles to shrink in size and for hair to fall out or stop growing. Fish products that are known to contain high levels of mercury like tuna, mackerel and swordfish can also cause hair weakening and excessive hair fall. Studies have also found that fried foods are associated with the production of high levels of DHT.

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.
Follicum announced yesterday it has successfully completed the development of a topical formulation for FOL-005. The company had been working in parallel to develop an optimal topical version of FOL-005 while an injectable version of the peptide was being used in a clinical trial. Now that the topical formula is completed it will be trialed in a further phase 2 clinical trial which will likely begin very late 2018 or early 2019.
The Holy Grail remains a drug that will promote regrowth, but this might not be so far away. Earlier this year, Manchester University announced that an osteoporosis drug had been found to have “dramatic results” promoting hair growth when applied to tissue samples in pre-clinical trials. The resultant frenzy left the PhD student responsible, Dr Nathan Hawkshaw, a little dazed. “Every other week, something comes out about hair loss and it doesn’t generate as much media coverage as what I experienced,” he grumbles. He’s in this for the science – there aren’t many fields where you get to mess around with real human tissue – but such is the distress caused by hair loss and such is the potential customer base that interest is always high.

A company not previously discussed in online news, SWITCH BIOTECH, has sights on developing a drug for androgenic alopecia. As you will see, the company is still in the very early stages of developing a therapy for AGA, however they are a knowledgeable dermatology-focused company and have a unique method of drug development. Here’s a quote from their website about working on AGA:

Products like these come from huge pharma companies and are the direct beneficiaries of tens and even hundreds of millions of dollars worth of research and development, compliance, production and advertising. Since drugs have the capacity to significantly change your bodily functions and can cause threatening and undesirable side effects, there’s a need for the government to protect consumers via tough regulations.
Stay away from tightly bound styles, like braids, buns, or ponytails. Resist twisting or rubbing your hair. And gently wash or brush hair, switching to a wide-toothed comb if necessary to prevent too much pulling at the roots. Hot rollers, curling or straightening irons, hot oil treatments, bleaching, and other chemical processes are other things to avoid.
Dr. Melissa Piliang, a dermatologist at the Cleveland Clinic, said that Rogaine works better on the top and crown (for reasons not fully understood, the frontal hairline tends to be more resistant to treatment) and ideally should be started as soon as women notice thinning. “Any regrowth you get is a minimal amount,” Dr. Piliang said. “So the more density when you start, the better results you get.”

Beware online stores selling Propecia without a prescription.Finasteride is FDA approved, but buying it online without a prescription can be illegal and dangerous. Prescription-free online stores have a reputation for selling placebos or dangerous replacements. We recommend speaking with a doctor about prescriptions or sticking to save over-the-counter treatments.

Studies have indicated that one of the ways to slow hair loss is by maintaining a healthy scalp environment. Regular shampooing aids in the prevention of genetic hair loss by removing excess sebum containing elevated levels of DHT. Unfortunately, there is no silver bullet hair loss shampoo on the market that will regrow a full head of hair in a couple weeks.
Know the different types of wigs. Synthetic wigs are easy to style and are less expensive than human hair wigs. On the other hand, wigs made from human hair have a more natural look and feel, and are more preferred by those with permanent cases of hair loss. Though they take longer to style, human hair wigs are worth an investment if you plan on wearing it for a relatively long period of time.
Keranique is another line of products targeted towards women. They offer a complete system consisting of shampoos, conditioners, and topicals. Our testers found that it was one of the harshest shampoos and was not always color safe. Their topical foam contains Minoxidil which can irritate some scalps. Keranique hair products are safe to use and highly effective.  They also have an anti-dandruff shampoo that has received amazing reviews.
The patient, a small, vaguely European man in his late forties, had rings on his fingers and a bloody, rectangular gash on the back of his head. It looked like a chunk of missing carpet. Bernstein pointed at the white opening of exposed scalp, and explained how easy it would be to stitch skin together over the gap. This was a traditional process for follicular-unit transplantation. Then Bernstein led me into a second room, where another patient was seated with his face in a massage-table-like padded hole. A portion of the back of his head was marked off. To his right was a boxy gray machine, roughly four feet by four feet, with a jutting mechanical arm. This was the ARTAS Robotic Hair Transplant.
Not only does Nioxin promise that its system will deliver on denser-looking hair, it also includes a long list of ingredients that  inhibit the conversion of testosterone into DHT. These ingredients include nettle extract and saw palmetto. While Nioxin does include ingredients which studies have indicated help block DHT, the primary focus of Nioxin is to improve the cosmetic appearance of thinning hair.
The average person loses 50 to 100 hairs per day naturally due to this cycle. But if the process is interrupted at any stage—for example, if the follicle doesn’t come back out of resting mode or starts to shrink—hair loss and hair thinning can result. Interruptions to the cycle can be caused by hormones, stress, poor diet, chemical hair treatments, certain medications, and, of course, good ol' genetics.
