Energizing Caffeine

Caffeine has been known for over 20 years for its special relevance in scalp-focused formulations.

Due to its molecular properties, it can be incorporated into scalp and hair care routines to help refresh the scalp and maintain healthy-looking hair.

It remains one of the most explored plant-derived ingredients in the context of scalp and hair care.

5,6-DHI Repigments the Hair

5,6-Dihydroxyindole, or 5,6-DHI for short, is a preliminary stage of the natural hair pigment melanin. When applied, 5,6-DHI binds directly to the hair, penetrates the hair shaft, and forms color molecule chains in the hair with oxygen. The hair becomes darker.

Our research focuses on solutions for the most relevant hair problems. To achieve this, we continuously search for new ingredients and develop formulations optimized for men.
