Does Nioxin work?

According to The Procter & Gamble Company, Nioxin produces thicker-looking hair within 30 days, but it does not produce new hair growth. Instead, it causes five distinct changes to the hair and scalp that enhance the appearance of thinning hair.

The Procter & Gamble Company explains that Nioxin strengthens hair so it is less prone to breakage and it appears fuller. It increases the texture of each strand of hair and prevents damage to the cuticle. Nioxin also cleanses the scalp and removes sebum buildup. This oil weighs hair down, making it appear thinner, and irritates the scalp. While Nioxin makes hair appear thicker, any individual seeking therapy to produce hair growth should consult a physician.
