Alpecin Tuning Shampoo 200ml is a caffeine shampoo designed for dark hair and the first signs of grey hair. Dark colour pigments help maintain and enhance the natural hair shade, making hair appear darker and fuller with regular use. The caffeine complex supports hair roots and helps reduce hereditary hair loss, while zinc and niacinamide contribute to scalp and hair care. Alpecin Tuning Shampoo 200ml is suitable for daily use and provides a gradual, washable colour effect.
