hmm, try losing your hair when you're 18 years old.
Dr. Bob Marshall recc Avena Sativa - or oat grass i think its called. idk if it works but might be worth a try. i notice for myself that the more Sugar i eat the more oily dandruff i get. maybe its related to fungus and hair loss.
most of the rest of that stuff migth be related to depression. you're early to mid 20s and you think the best years of your life are ahead of you and instead you look in the mirror and things just get worse and worse and you wonder if God f'ing hates you.
