where does gray hair come from?

Where does gray hair come from? It seems that the secret was discovered by New York and Japanese researchers. “First a precision, gray hair does not exist, in reality, there is black hair and white hair, it is the mixture of the two that gives the impression of gray”specifies the doctor and journalist Damien Mascret, present on the set of 12/13, Tuesday April 25. “A hair becomes white when it has no more ink to color it (…). Stem cells need to activate into cells full of ink, melanin, and move into the root of the hair” to color it, explains Damien Mascret.

“But what the researchers discovered is that the cells can get stuck in the root. As a result, they no longer charge. The next hair that will grow will therefore be white”he reveals. According to legends, the hair of Marie-Antoinette, who was waiting for the guillotine, turned white overnight. Is it possible ? Yes because “significant or prolonged stress (…) will stimulate the stem cells which will all activate and empty themselves at the same time and no longer return to the niche to recharge. So it will be final.concludes Damien Mascret.
