I have been experiencing a lot of hair loss as of late. I am 23 year old, have a full head of thick hair. but in the past year or so I have been noticing alot of hair falling out especially when having a shower, it seems to me when I just run my fingers through my hair (when wet), there is a lot of hair that comes out. should I be worried? I really don't want to lose my hair at this early stage in life. What do you think are the causes of this? keeping in mind I have not been depressed or stressed lately, can anyone give me any practical advice (in terms of diet, best shampoo to use) to ensure that I keep my hair strong and healthy. As for genetics, my dad is in his late 50s and he has a full head of hair, as for a brother who is in his late twenties, he has really bad hair loss.
