To help with my scalp hair loss I use a product called Nioxin. It can be purchased at most beauty salons or your stylist center. I use the shampoo, conditioner and advance therapy for extremely thinning hair. You rub the product on and leave it in. I have noticed small hair follicules where I was missing some. I also notice I have ALOT more hair loss when I stop using it. They have introduced and new line that helps to smooth curly and dry hair too.
Good luck.
