* Alpecin Double-Effect Shampoo against dandruff and hair loss (hereditary). with Caffeine Complex.* Why double effect?  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 Shampoo.  # 1st effect:  In the first step, this Double-Effect 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 recommendable, because it takes into account all dermatologically  relevant aspects of cosmetic dandruff:  - Gentle dandruff removal  - Anti-inflammatory action  - Antioxidant effect, i. e. improved resistance  - Antimicrobial properties  In the past, this combination was exclusively used in phamacy products as a dermatologically based anti-dandruff solution.  It allows a precise and gentle micro-peeling (micro-exfoliation) and relieves scalp itch.  # 2nd effect:  The removal of dandruff from the scalp has prepared the way for the caffeine complex. Alpecin Double-Effect 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.* Ingredients:  Aqua, Sodium Laureth Sulfate, Laureth-2, Disodium Laureth Sulfosuccinate, Sodium Lauroyl Glutamate, Caffeine,  Panthenol, Parfum, PEG-120 Methyl Glucose Dioleate, Hydrolyzed Wheat Protein, Salicylic Acid, Sodium Chloride,  Piroctone Olamine, Sodium Citrate, Potassium Sorbate, Citric Acid, Polyquaternium-7, Menthol, Sodium Benzoate,  Zinc PCA, Niacinamide, Limonene, Tetrasodium Etidronate, Phenoxyethanol, Methylparaben, Propylparaben, CI 60730.  - Salicylic acid provides antimicrobial action, prevents the formation of new dandruff on the scalp and gently removes the top dandruff layer.  - Octopirox provides antimicrobial action and prevents the formation of new dandruff on the scalp.  - The caffeine complex activates the hair roots, extends the hair growth phases and improves hair growth.* Dr. Kurt Wolff.
