I recently started using a shampoo that's supposed to help, Pura d'Or Advanced Therapy Biotin. It has great reviews, and the majority of the ingredients are organic. It's not water based either, it's made with aloe vera instead. Love these things about it. Hope it works. Has anyone here tried it before and had any positive results? It's too early for me to be sure if it's doing anything--only a couple of weeks.
