Dr. Mercola Hair, Skin & Nails, 30 Capsules (30 Servings), with Biotin, Solubilized Keratin, and Low Density Hyaluronic Acid, Non GMO, Gluten Free, Soy Free

Have only been using the product for about 14 days so it isn’t possible yet to comment on efficacy. However as a Mercola product I anticipate that it will work and my hair will become healthy, thick and lustrous!

Holy hair, skin and nails growth, Batman! I was not too sure. These would actually work to help care and nails be healthy, but I was very pleasantly surprised. It’s not an instant thing, but after a while of taking them hair is stronger nails grow longer, I am quite impressed.

Has helped my nails and hair a lot. Nails don’t break as easily and hair feels thicker.

Recommend by DNA consultant for hair loss, haven’t finished the first bottle.

Dr Mercola brand is the best brand of suplements and vitamins. I recommend it 100%

I have been having a lot of hair loss that has caused my hair to be noticeably thinner, not just by me, but others have commented on it. I started taking this product for roughly a month and I there has been a noticeable reduction in hair fallout. I had been using a different biotin supplement that usually worked for me, but I believe my current hair fallout is related to diet and I thought to try a supplement with "keratin". This product works. I give four stars because I think it would have worked faster/better had the biotin been higher.
