Due to excessive styling products, I have noticed that my hair have started falling and among many solutions to thinning hair, I could choose for nioxin, as people rated it quite effective in hair growth. I just want to know from you guys who have ever used a nioxin product for hair, which method of using nioxin works most efficaciously? Does nioxin work in form of nioxin scalp therapy, or it makes an effective shampoo/conditioner, or would it be as a part of supplements for hair growth? Please advice.
