Product Information

The Dual-Action Solution

Alpecin Double-Effect Caffeine Shampoo targets the two most common scalp problems affecting men. In the first stage, it loosens crusty dead skin cells and thoroughly removes dandruff from the scalp. In the second stage, once the dandruff is cleared, the high-concentration caffeine complex penetrates the hair roots to strengthen them against hereditary hair loss.

By clearing the "pathway" first, Alpecin ensures that the caffeine isn't blocked by a layer of skin cells, making it more effective than using separate, non-specialised products.

How the "Double-Effect" Works

Stage 1: Loosening the Dandruff The formula contains Salicylic Acid and Piroctone Olamine. These medical-grade ingredients act as a gentle exfoliant, antimicrobial, and antioxidant.

  • They effectively dissolve the "glue" holding dandruff flakes together.
  • They reduce scalp inflammation and itching.
  • They discourage the growth of microorganisms that cause dandruff.

Stage 2: Energising the Roots With the scalp cleared, the Caffeine Complex can travel directly along the hair shaft.

  • It counteracts the exhausting effect of testosterone on the hair roots.
  • It provides the roots with the energy needed to extend the hair growth phase.

Key Benefits & Features

  • Two Solutions in One: Saves time and money by treating dandruff and thinning hair in a single wash.
  • Gentle Exfoliation: Salicylic acid provides a professional-level scalp "peel" to keep skin healthy.
  • Prevents Premature Loss: Strengthens hair roots that are weakened by hereditary factors.
  • Clinically Tested: Developed by Dr. Wolff Research to ensure the caffeine remains detectable in the hair follicle for 24 hours.

How to use

How to Use for Best Results

To allow the "Double-Effect" to work, the contact time is crucial:

  1. Apply: Massage a small amount into wet hair and the scalp.
  2. The 2-Minute Rule: Leave the shampoo on your scalp for exactly 2 minutes. This is the time required for the caffeine to penetrate the roots.
  3. Rinse: Rinse out thoroughly.
  4. Frequency: Use daily. If you do not wash your hair every day, use the Alpecin Caffeine Liquid on non-wash days to maintain the caffeine depot.

Common Questions about Alpecin Double-Effect

Is this better than the standard C1 Caffeine Shampoo?

If you have both dandruff and thinning hair, yes. If you only have thinning hair and a clear scalp, the standard Alpecin C1is sufficient. The Double-Effect is specifically for those who need the exfoliating power of Salicylic Acid.

Does it work for oily dandruff?

Yes. The Salicylic Acid is particularly effective at breaking down the oils that cause flakes to stick to the scalp, making it ideal for oily dandruff types.

Will it make my hair feel dry?

Because it exfoliates the scalp, some users with naturally dry hair may find it slightly more drying than a moisturising shampoo. We recommend focusing the massage on the scalp rather than the ends of the hair.
