First effect - Tough on dandruff: In the first step, this shampoo loosens scaly, keratinous cells and thoroughly removes dandruff from the scalp. From a dermatological standpoint, the combination of the two effective anti-dandruff substances, salicylic acid and piroctone olamine, is an ideal complex because it takes into account all dermatologically relevant aspects of cosmetic dandruff:
Gentle dandruff removal
Antioxidant effect, i.e. improved resistance
Up to now, this combination was exclusively used in pharmacy products as a dermatologically based anti-dandruff solution. It results in precise and gentle micro-peeling (micro-exfoliation) and relieves itching scalps.
Second effect - Prevents hereditary hair loss: The removal of dandruff from the scalp prepares the way for the caffeine complex. Alpecin Double-Effect Caffeine Shampoo contains highly dosed caffeine that penetrates into the hair roots when the hair is washed. It can be detected just 120 seconds after application. In the hair root, the active ingredient forms a 24-hour depot, thereby protecting the hair root from premature inactivity and, as such, hereditary hair loss is prevented.
