*A little background information on biotin*
I was wary of trying this because I've read that too much biotin (the main vitamin in these types of supplements) may cause acne for some people. Why does biotin cause breakouts? I've done some research on this before and apparently when you take such high doses of a certain vitamin, it can cause imbalances in the body, which in turn creates side effects such as acne.
In addition, you should be drinking a lot of water if you are taking this. Biotin is a water-soluble vitamin, which means it needs water to break down entirely in your body. You should be drinking the daily recommended amount. (I know I certainly don't, but I really should.)
Here are my results:
Week 1: No apparent change in hair, no apparent change in nails, 3 pimples came up
Week 2: Noticed less hair fall than usual, nails feel harder and stronger and grow a lot faster, huge breakout across my forehead
I stopped after week two because I was so unhappy with what it was doing to my skin. I got so many pimples and they weren't the small, colorless kind I usually get. These were the bumpy, red, painful ones! The only thing I liked was that my nails were improving and growing much faster than before. I know that two weeks is not a long time to test out a product like this, but I didn't really want to sacrifice my skin for the sake of my hair –it's like a double edged sword. :/
Based on the results with this product, I would give it 2 out of 5 stars. ★★☆☆☆
Part of this can't be blamed on the product itself, because it depends on the individual, like the way my body responds to it and the fact that I should drink a cup or two more of water each day. While this supplement may be very effective for some people, unfortunately for me, it just does not work.
