I started using the Nioxin Thinning Hair System (step 2) about 6 months ago and it works for me - and my dermatologist agrees! The scalp treatment is like a mousse and according to my dermatologist, since it doesn't have an active ingredient, it does not promote hair growth. The scalp treatment lifts the hair and makes it more full looking. The shampoo, conditioner, and scalp treatment all have a great scent. I am very pleased with this product and I highly recommend it!
