Protect the scalp during the hair-coloring process. Scalp Protect Serum is a salon-exclusive, dermatologist tested pre-color treatment with anti-irritation ingredients. With NioProtect Technology, the serum contains anti-irritation ingredients that help to protect the scalp during the oxidative coloring process. It remains on the scalp like a glove that protects the hand. The fragrance-free Scalp Protect Serum was tested in the presence of a dermatologist and has a pH value very similar to the scalp skin.
