now i know why my hair is prone to falling,it is because i keep on pulling it continously whenever i am idle or thinking much.This is pleasure for me for the time being,but then what about my hair, it has to bear the brunt of my cruelty towards it.I have lovely brown hair that i dont want to loose so easily as i am only twenty five years of age.and this is not a good age i suppose for hair falling.Then when i went to to my aunt for a vacation she told me about N-acetyl-l-cysteine .in what way does N-acetyl-l-cysteine help in preventing me from not taking out strands of my hair?
