What do you know about grey hair ?

The bleaching of hair from grey to white is called canities. After a life cycle of four years and a a dozen hair growth, the hair get tired and the more we get old the more the melanin, which gives pigmentation, decreases. It is replaces by air bubbles which lead to grey hair !

Some of us will have grey hair at different ages. There is no escape but like in the song of Maxime Le Forestier "né quelque part" (born somewhere), we are not all equal before that natural phenomenon. Genetics has its part in it but some behaviors are said to promote canities, for example, an excess alcohol/tobacco consumption. There also the relation between stress and greying but nothing scientifically proved !
So, having grey hair, it's normal but… assuming it it's another thing.

Fortunately, some hairdressers colorists promote that tendency. Adopt a short and structured haircut because white with long hair seems fast sloppy. By the way, the ex-brunette but still singer Lio had to support the critics during her apparition in the program Village départ: she appeared with greying hair… but she was not tong-tied, she declared that that she assumed totally her 52 years, her natural look considering she didn't have to precise anymore that "brunes ne comptent pas pour des prunes" !
Conclusion : to assume her white or grey hair, you must have a strong character.
