Answer: Well, the most common and popular products for skin health (including the scalp) are Fish Oil (which I use for my skin problems), Biotin, Silica (available naturally in Horsetail herb), MSM, and Hyaluronic Acid among the most popular items. Different people have different reactions to those different ingredients, so it's hard to say what may help most for you. I've personally taken Biotin (which helps for a lot of people), but it was too powerful for me, so it shows how different people can be.
