The effective hair pigments in Alpecin Tuning Shampoo keep dark hair looking dark. This colour effect is inconspicuous and only becomes more intensive with regular use. It gradually washes out when normal shampoo is used.
In addition, Alpecin Tuning Shampoo also prevents hereditary hair loss. Washing your hair daily with the shampoo supplies the hair roots with the activating caffeine complex. Alpecin Caffeine can be detected in the hair roots after just 120 seconds of residence time.
