Why the double effect?
Hair loss and dandruff, are the two most frequent scalp problems to affect men.
As a hair care product specially for men, Dr. Wolff Research has developed the Alpecin Double-Effect Caffeine Shampoo that simultaneously counteracts both problems.
1st effect:
Tough on dandruff
In the first step, this Double-Effect Caffeine 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
- Anti-inflammatory effect
- The antioxidant effect i.e. improved resistance
- Antimicrobial properties
Up to now, this combination was exclusively used in pharmaceutical products as a dermatologically based anti-dandruff solution. It results in precise and gentle micro-peeling (micro-exfoliation) and relieves itching scalps.
