avacor isn't natural and CERTAINLY isn't without side-effects.
folic acid, biotin, paba, and b5 vitamin are natural supplements that MIGHT help... but, honestly, don't count on it. you're honestly normal... you're not losing your hair or anything. you'll have the same results, i think.... hair is natually supposed to fall out everyday. 3-4 hairs in the shower is way less than normal, which means that your hair won't go anywhere for a long, long time.
saw palmetto helps block something called dht, which is a form of testosterone, which causes hairloss. however, like i said before, your "hair loss" isn't really hair loss at all.... if you went to the doctor's office and asked him wtf, he'd probably laugh at you and tell you to quit wasting his time and that you're perfectly normal and are at no risk of losing your hair anytime soon.
