The Nioxin 3 Scalp Therapy is the conditioning step in the Nioxin Systems for thinning hair. Nioxin Scalp Therapy System 3 is specifically made for fine, chemically enhanced, normal to thin looking hair. The Glyco-Color Shield in this conditioner for thinning hair protects hair color and protects the scalp from being damaged by chemicals. Nioxin Scalp Therapy System 3 is a conditioner for thinning hair that moisturizes and energizes the scalp and hair. The vitamins, proteins and amino acids in the formula help strengthen the hair and relieve any tightness. BioAMP helps to thicken the hair from inside the cuticle for thicker, more voluminous hair. Moisturizing nourishment is continuously delivered to the scalp and hair using a time-released delivery system called Transactive Delivery System.
