5000 mcg of biotin taken daily. No real side effects or possibilty of overdosing as biotin is water soluble %26amp; the body excretes what it does not use.What is a good hair growth treatment?
so try this...regular trims are a must, about every 7-9 weeks. if its been awhile since you have had a trim then inches may be called for to get to healthy hair. i use vitamin e on fresh washed hair.(its a vitamin that can be purchased where you buy vitamins, cut open capsule, squeeze into hand, rub hands together and apply to hair) dont message into scalp. if you get too much then just rewash it. hair will feel slightly sticky until dry then it will be nice and soft. it tames the frizzies, deep conditions and makes hair grow about three in a month. it takes about a month for the e to kick in. dont brush your hair but maybe once a week to message the scalp, i use a wide tooth comb at other times. brushing breaks off hair. i just started biotin vitamins two months ago this sat and notice and big growth spurt from that. biotin is cheap. i also have the biotin shampoo that i got from a vitamin store online. five bucks for a big bottle and a big bottle of E is about 8 bucks. the biotin is about 3 bucks. good luck
Try rogaine. It is probably the most effectively used product out there right now.
