Hi, Thanks for writing to us. What you are having is known as trichotillomania. It is basically an impulse control diorder where on has a strong compulsive urge to pull hair. As mentioned grief, stress anxiety can initiate it. No hair supplement would work. You basically have to control this urge. Indulge yourself in meditation, yoga, long walks, family/friends gathering, reading books etc. The idea is to keep your self stress free. If this does not help you may meet a psychiatrist to start psychotherapy for same. Also drugs like sertraline, fluoxetine can be used to control it to some extent. The bald patch will have hair growth once it is left untouched. Hope this helped. Hope this helped
