Hair loss Gene discovered

Tokyo, Japan - Scientists have identified a gene linked to hair loss. Its study could enable the development of new treatments against baldness and the anticipation of hair loss among young men.

The gene Sox21 had already been linked to the formation of nerve cells, but this new study seems to indicate that it also ensures the maintenance of hair. A discovery that could help scientists develop new treatments.

Researchers have uncovered its properties in experiments on mice which also carry this gene. They blocked the activity of the gene in mice and found that the rodents began to lose their head hair about 15 days after birth, before ending up completely naked in a few weeks. "It's quite possible that the gene is also a partial cause of baldness in humans," said Dr. Yumiko Saga of the National Institute of Genetics, Tokyo.

Have a hair growing long, 2 years or more, followed by a short resting phase two or three months. But when some men get older, this pattern is reversed so that at times the resting phase is so long that the new hair do not grow and can not replace 100 to 150 hairs lost daily. Japanese researchers believe the gene Sox21 governs this cycle.

Dr. Bessam Farjo, medical director of the Institute of TRICHOLOGY, believes this study could help find a treatment against hair loss. "It will also help to target people likely to lose their hair so that we can treat them before it happens" he adds. At the moment there is no cure but pills and lotions that help prevent regrowth. At the age of 60 years, more than two-thirds of men are affected by the baldness.
