The Alpecin Double Effect combines two actions.

Alpecin Caffeine Complex: Strengthens the hair roots
Anti-Dandruff Complex: Piroctone Olamine & Salicylic Acid against dandruff
Scientifically proven effectiveness
Caffeine stimulates the hair roots
Caffeine has been known for more than 20 years for its growth-stimulating effect on hair roots. It inhibits the breakdown of the intracellular messenger cAMP. As a result, more energy is available to the cells and cell growth is stimulated.
Caffeine is therefore the most researched active ingredient of plant origin against hereditary hair loss.
- Zinc and niacinamide: Zinc and niacinamide promote energy metabolism and can ensure better nutrient supply to the hair roots.
- Salicylic Acid: Salicylic acid is originally an extract from willow bark. In cosmetic products, salicylic acid has antibacterial and anti-dandruff properties.
- Piroctone Olamine: The ethanolamine salt of a 2-pyridone derivative has fungicidal and antibacterial effects and is particularly effective against the yeast fungus Malassezia furfur.

FAQAnswers to your questions
In principle, yes. Thanks to the double effect, i.e. the simultaneous action against dandruff and hair loss, the shampoo prevents hereditary hair loss and gets rid of annoying dandruff. Both causes are permanent, i.e. the hereditary predisposition and the risk of skin irritation and dandruff caused by microorganisms and sebum persist throughout life.
By massaging the head with Alpecin Double Effect Caffeine Shampoo, the active ingredients are better absorbed by the skin and the hair roots and a supply of active ingredients (depot) is created. In addition, the gentle pressure removes the top cuticle layer more effectively.
