The two most common scalp problems are hair loss and dandruff. The Dr. Wolff research has developed a shampoo that counteracts both problems at the same time - the Alpecin Doppel Effekt Coffein Shampoo.
In the first step, the double-effect caffeine shampoo loosens the encrusted horny cells and thoroughly frees the scalp from dandruff. The combination of the two effective anti-dandruff substances salicylic acid and piroctone olamine is a complex that is recommended from a dermatological point of view because all dermatologically relevant aspects of cosmetic dandruff formation are taken into account.
Freeing the scalp of dandruff now clears the way for the caffeine complex. Alpecin double effect caffeine shampoo contains a high dose of caffeine that penetrates into the roots of the hair while you are washing your hair. It is detectable after only 120 seconds exposure time. The active ingredient forms a 24-hour depot in the hair root and thus protects the hair root from falling asleep prematurely
