Basically I'm not sure how to quantify how well this product works, given that I'm a single consumer and not a laboratory. However, what I CAN say is that it's an excellent price for Biotin, and that the capsules are small and go down the hatch easily.
21st Century Health Care, Biotin, 5000 mcg, 110 Capsules

People take mega-doses of biotin for hair growth, I'm not risking my health for that. I started with half this dose a few months ago and my hair is definitely growing faster. What I want is both thickness and length and the thickness part is harder to tell than the length. So we'll see :) High hopes for beautiful locks. . . . .
가격 경쟁력이 있음.

원래 먹던 것과 같은 정량인데 가격이 저렴해서 구입해 봤어요~~~ 비오틴은 꾸준히 먹으면 탈모에도 효과가 있습니다.
