earlier i used to have such shiny, and healthy hair but as i grew up they started showing signs of damage and started breaking from the sides.when i told this to my friend she said that this could be the result of my weakened hair from the scalp which is the reason when i trying moving my fingers through my hair,they tend to come out in my hands and even can be seen fallen in my clothes,the washroom and whatever i eat.and she then also told me to use Kerastase Products.what are the kinds of Kerastase Products that help in tightening weak hair making them resistant?
