Great value

Posted by NaturopathGabby on Jun 25, 2016

This biotin is cheap as chips so I was skeptical about it, but after taking it for a month or so i noticed stronger nails and hair (particularly the nails though). I haven't needed to take it since then - great to see long term results.

These are good, I noticed a HUGE difference in my nails they were so much stronger, and my skin did look a bit better texture wise, and I noticed more growth in my body hair but not so much in the hair on my scalp.
