Growth and dandruff are the two most common scalp worries in men. Dr. Wolff Research has produced a shampoo that helps to combat both problems: Alpecin Double-Effect Caffeine Shampoo.

The initial function of the Double-function Caffeine Shampoo is to loosen scaly, keratinous cells and eradicate dandruff from the scalp.

The second effect is the eradication of dandruff from the scalp, which prepares the way for the caffeine complex. Alpecin Double-Effect Caffeine Shampoo contains caffeine, which stimulates the hair even throughout the washing process. The minimum residence time for this product is similarly 120 seconds. Once at the hair root, the active component develops a 24-hour depot, preventing premature inactivity.
