Alpecin C1 Caffeine Anti-Hair Loss Shampoo for Men 250 ml Dr. Kurt Wolff is a high-quality caffeine shampoo that helps to deal with hair loss. Alpecin C1 Caffeine Anti-Hair Loss Shampoo for Men 250 ml Dr. Kurt Wolf has its beneficial effect thanks to the caffeine it contains. This ingredient stimulates hair growth and slows down the onset of hereditary hair loss. When washing your hair, caffeine reaches the roots of the hair shaft and penetrates, so its effect continues even after rinsing. In about 2 minutes, caffeine travels along the hair shaft and reaches the hair follicle. And when it is left to work for a longer time, caffeine penetrates and has a beneficial effect on the scalp itself. The special formula of the product is also enriched with Zinc and Niacin, helping to strengthen the roots and all hair. It does not contain softeners and favors the healing of the hair structure.
