Nioxin Shampoo System 4 helps thicken fine, thinning hair by gently cleansing and removing DHT and other residue. Also provides nourishment in order to thicken the hair shaft from inside the cuticle. Helps protect the hair and scalp from the excessive drying effect of chemical services.
Apply to wet hair. Lather 1 minute. Rinse.
"I have been using the system 1 for over a decade and have noticed that I am no longer losing hair and it is growing better, looks better and is healthier."
