The ultimate anti-dandruff shampoo, the Alpecin Double Effect shampoo boasts a unique dual action formula which gently but efficiently removes dandruff whilst soothing the scalp. Containing salicylic acid and piroctone olamine, two highly effective anti-dandruff ingredients, this shampoo provides instant non-inflammatory action, relieving the scalp of itching and using gentle micro-exfoliation to leave you feeling refreshed and clean.

Also made with a high dosage of caffeine which penetrates deep into the hairs roots whilst washing, this shampoo promises to reduce and prevent dandruff with noticeable results.

These two most frequent scalp problems affect men: growth and dandruff. Dr. Wolff Research has developed a shampoo that simultaneously helps to counteract both problems: Alpecin Double-Effect Caffeine Shampoo.

1st effect:

In the first step, this Double-Effect Caffeine Shampoo loosens scaly, keratinous cells and removes dandruff from the scalp.

2nd effect:

The removal of dandruff from the scalp has prepared the way for the caffeine complex. Alpecin Double-Effect Caffeine Shampoo contains caffeine that stimulates the hair already during hair washing. The minimum residence for this product is also 120 seconds. Once it arrives at the hair root, the active ingredient forms a 24-hour depot, thereby protecting the hair root from premature inactivity.
