Do not dye your hair

Mode of action: 5,6-DHI + Alpecin Caffeine Complex

A black structural model against a white background represents the active ingredient 5,6-DHI in Alpecin Repigmentation Shampoos.

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 colour molecule chains in the hair with oxygen. The hair becomes darker.

Caffeine stimulates the hair roots

Caffeine has been known for more than 20 years for its growth-stimulating effect on hair roots. It inhibits the breakdown of the intracellular messenger cAMP. As a result, more energy is available to the cells and cell growth is stimulated.

Caffeine is therefore the most researched active ingredient of plant origin against hereditary hair loss.

Complementary active ingredients

Zinc and niacin promote energy metabolism and can improve nutrient supply to the hair roots.
