Why is hair dry and damaged?
We can't fight our genetics, hair may be dry or very dry by nature, which leads to poor scalp irrigation and insufficient sebum secretion. But there are also things you can put it through: a hairdryer that is too hot, unnecessary brushing, inappropriate care, etc. If you add to this the explosive cocktail of sun, wind, sea water, chlorine, pollution, UV and stress...the consequences were always expected. The hair fiber is damaged, causing dry hair.
What happens deep in the hair fiber when you have dry hair?
Disappearance of the hair's protective barrier (or hydrolipidic film)
Attacked by hair styling and other aggressions (straighteners, bleaching, hair dryers, chlorine, etc.), this protective surface shield no longer plays its role as a barrier for the hair fiber.
The hair’s scales are removed
Like tiles on a roof, the scales are interlocked. When degraded, they break apart and expose the inside of the hair. As a result, the water naturally present in the hair evaporates excessively and the hair dries out.
