Japanese Scientists Identify Hair Loss Gene, Sox21

HONG KONG (Reuters) - Researchers in Japan have identified a gene that appears to determine cyclical hair loss in mice and believe it may also be responsible for hair loss, or alopecia, in people.

In a report published in the Proceedings of the National Academy of Sciences, the scientists described how they generated a line of mice that were lacking in the Sox21 gene.

"The mice started to lose their fur from postnatal day 11, beginning at the head and progressing toward the tail region of the back," they wrote.

"Between day 20 and day 25, these mice eventually lost all of their body hair, including the whiskers. Intriguingly, new hair regrowth was initiated a few days later but was followed by renewed hair loss."

The cyclical alopecia continued for more than two years and the researchers observed that the mutant mice had enlarged oil-secreting sebaceous glands around the hair follicle and a thickened layer of skin cells during periods of hair loss.

The normal cycling of hair follicles through their resting and growing phases causes a shed of  approxmately 100-200 hairs from the scalp per day.   However, hair follicle cycling problems in humans may cause a condition such as telogen effluvium (severe, synchronized shedding) which, to date, has no truly effective treatment.   Telogen effluvium is more common in women and may or may not occur in conjunction with ‘traditional’ hereditary female pattern hair loss--where hair density and hair caliber is normally lost progressively over time in a specific pattern.   An 'effluvium,' or shed, may be noticeable during different times of the year or even various times of the month as well as a consequence of crash diets, high-stress, hormone imbalance, childbirth, menopause, etc.    Severe shedding can cause significant concern for those worried about hair loss as hair volume may change dramatically as well as scalp coverage.


Genetic hair loss testing is available for men and women to determine their risk for developing the condition, by looking at the well-documented association between the Androgen Receptor Genes or ‘CAG repeat’ scores and the development of hereditary male or female pattern hair loss. Evaluation by a board-certified hair restoration physician is recommended for those who are experiencing severe shedding, decreasing coverage of their scalp, decreasing hair volume, receding hairlines or widening part-lines.  


Diagnostic evaluations, such as microscopic hair density and hair caliber analysis, genetic testing and counseling can be performed.  Treatments, based on the diagnosis, can then be initiated.


Medical treatments, like minoxidil (Rogaine), laser therapy, nutritional modification, other medications and even hair transplantation can be used to treat hair loss successfully.

Predict Your Propecia Response with a New Genetic Test For Male Pattern Hair Loss

Thinking about starting Propecia (finasteride), but are unsure if it will work for you?    A new genetic test which predicts your “Finasteride Response” is now available from Dr. Alan Bauman at Bauman Medical Group.   The Genetic Test for Finasteride Response can predict whether you are a good candidate for medical treatment with Propecia (finasteride)—the only oral fda-approved treatment for male pattern hair loss.    

Is taking Propecia (finasteride) worth it?   The Genetic Test for Finasteride Response will help determine if you are likely to have a slight, moderate or great treatment response to finasteride.   Knowing your predicted response to finasteride will help you decide if you should start or continue treatment.

What does the test tell you?  The Genetic Test for Finasteride Response provides men with a score, called the ‘CAG repeat’ score.   A smaller CAG repeat score is associated with an increased response to finasteride for the treatment of male pattern hair loss.  Scientists discovered that among men that had the best response to Finasteride, approximately 70% had a CAG score below 22, while men that had a subtle response to Finasteride approximately 70% had a CAG score above 22.

The Genetic Test for Finasteride Response is a painless, non-invasive, cheek-swab which takes just minutes to perform.  Results from the genetic test performed on the sample are reported in just a few weeks.

The original Genetic Hair Loss predicts your chances of experiencing severe hair loss.

SPECIAL OFFER:  New Propecia patients can receive a FREE Genetic Finasteride Response Test at the time of their initial consultation with Dr. Bauman for a limited time (expires 6/12/09).   This is a limited time offer from Bauman Medical Group and some restrictions apply.   For more information on the FREE Genetic Finasteride Response Test, email or call 561-394-0024.

LLLT expert, Dr. Michael R. Hamblin, scheduled to speak at ISHRS 7/2009 on laser hair growth

Originally uploaded by Dr_Alan_Bauman

Harvard researcher, Dr. Michael Hamblin is scheduled to lecture on the Mechanisms of Low Level Laser Therapy at the ISHRS conference in Amsterdam in July 2009. This highly-anticipated lecture will literally 'shed some light' on the scientific basis of phototherapy and its use in hair growth, wound healing, etc. for a large audience of physicians who may be unfamiliar with the basic science behind this 40-year old modality.

For a preview of Dr. Hamblin's much-anticipated lecture, please download and read the following white-paper he authored on Low Level Laser Therapy-Induced Hair Growth which covers the basic science theories of LLLT and explains why LLLT may help those with androgenetic alopecia (male and female pattern hair loss).
