The faulty genes in the X chromosome are the reason why we lose hairs. There are, of course, treatments, however I didn’t used any. Yes, I am starting to lose some hair and I don’t like it. It seems that living healthy will in deed help. So, less fast food, more exercise and, why not, eating at regular hours (which I have only started to do almost religiously).
Do we have some bald readers out there?
