Supports scalp health: the cleansing formula gently removes buildup and excess sebum to create a healthier environment for hair follicles.
Protects color-treated hair: formulated to provide color protection while delivering essential nutrients.

Ingredients and key components

Niacinamide — supports scalp health and helps nourish hair follicles, contributing to a healthy environment for hair growth appearance. Biotin — a vitamin associated with hair strength, supporting resilient strands. Caffeine — stimulates the scalp and may help refresh the scalp and strengthen hair at the root. Peppermint Oil — provides a cooling sensation and helps cleanse the scalp. UV protecting ingredients — help shield the scalp and hair from UV-related damage. Additional actives include cleansing and conditioning agents, moisturizers, and botanical extracts that support moisture balance and manage buildup. These ingredients work together to deliver the three-step regimen’s benefits while helping protect color and minimize breakage.

The three components are:

Shampoo — a gentle cleanser that removes buildup and prepares the scalp for the next steps.
Conditioner — nourishes and restores moisture balance, helping protect against breakage.
Treatment — a scalp-targeted formula that delivers nutrients and antioxidants; contains UV protecting ingredients and should be applied to the scalp and massaged in without rinsing.
