The two most frequent scalp problems affect men: hair loss and dandruff. Dr. Wolff Research has developed a shampoo that simultaneously counteracts both problems: Alpecin Double-Effect Caffeine Shampoo.
In the first step, Alpecin Double Effect Caffeine Shampoo loosens scaly, keratinous cells and thoroughly removes dandruff from the scalp.
• Gentle dandruff removal
• Anti-inflammatory action
• Antioxidant effect, i. e. improved resistance
• Antimicrobial properties
In the 2nd step, the removal of dandruff from the scalp has prepared the way for the caffeine complex. Alpecin Double-Effect Caffeine Shampoo contains highly dosed caffeine that penetrates into the hair roots already during hair washing. It can be detected after just 120 seconds of residence time. In the hair root, the active ingredient forms a 24-hour depot, thereby protecting the hair root from premature inactivity.
Medical studies have shown the positive affect of Alpecin Double Effect:
• Alpecin Double-Effect Caffeine Shampoo in comparison to the leading market reference product against dandruff
• Caffeine neutralizes the negative effect of testosterone
