I haven't been consistent enough to tell if it is working or not, but i will keep using it. 800 mcg great dose to use along with the multivitamins.

Good product for hair

I am not sure if the amount of biotin is enough, as before I used 2000mg, but so far so good. let your body adapt to the norms, as it might give constipation. but that is biotin itself ..
