Biotin 1000mg a day is working like a charm for me
I was worried about losing my hair (stress from work)
When I gave it a little tug a few pieces would fall out, it looked to me like more than normal. So I talked to my aunt who does hair replacements and such. She said Biotin so I tried it and it is working great!
Now if you are destined to lose your hair it will go, but if you are using DHT producing chemicals and or stress it will help tremendously
