Hey, I've had Nature's Bounty Hair, Skin and Nails Argan Oil infused supplements and it has been working very well for me. Although a major part of our hair and skin quality depends on the protein intake. Hence, I started eating a lot of protein rich foods including Tofu, Hummus, Yogurt and such. I also started with Ace Blend protein powder, as its natural and plant based powder, so the risk factor of side effects eliminates. It provides nourishment to skin and health as it has antioxidants so addresses our basic concerns too. I really like the product! You can try it too.
