If you want your hair to grow back this is what you use
I've been using this product for a month now with Nioxin shampoo & conditioner and all I gotta say it works. I see little hairs growing! Also it says that it's specific to just the rear of the scalp but I'm using it on the front of my hair and it's growing back.
Great product! Been using for years and really helps hold onto existing hair making them stronger. I use this product every other night and between those applications I use with Nioxin Diamax which thickens the hair. Great products.
