I seemed to be losing a lot of hair in the shower and had read that phosphate increased hair loss. For that reason, I was trying several different products when I first came across Nature's Gate Biotin Strengthening products at my local health food store. I was looking for phosphate-free, natural hair products and Nature's Gate was reasonably priced at the health food store. Nature's Gate Biotin Strengthening products have a pleasant scent. I have dry, color-treated hair that fights frizz and fly-aways. My scalp and hair felt clean and moisturized with continued use AND THERE WAS LESS HAIR IN THE SHOWER DRAIN!! Nature's Gate Biotin Strengthening products seemed to tame some of the frizz and fly-aways. but did not completely do away with them. I have yet to find a product that tames my frizzy, curly hair completely. I've been very pleased with this product and highly recommend it.
