Mode of action: DMG promotes the micro-blood-circulation of the scalp

Hair loss* is effectively reduced.

Micro-blood-circulation: The foundation for healthy hair growth

In areas affected by hair loss, this is reduced to below 40 %.

This is where DMG comes in:
Its mode of action, comparable to Minoxidil, ensures improved micro-blood-circulation and the hair roots are once again supplied with nutrients.

Additionally, caffeine stimulates the hair root

Caffeine has been known for over 20 years for its growth-stimulating effect on hair roots. It inhibits the breakdown of the intracellular messenger cAMP. This provides cells with more energy and stimulates cell growth.

Caffeine is thus the most researched plant-based active ingredient against hereditary hair loss.

Caffeine + DMG: Even more effective when combined

Individually, caffeine and DMG are already highly potent active ingredients. In Alpecin's unique, patented active complex, they are now even more powerful.

The result: Hereditary hair loss is now effectively reduced and hair growth** can be increased.

Measurement method: First-time evaluation of more than 10.000 individual hairs

Focus on a screen displaying a close-up of scalp hair, illustrating that Dr. Wolff, in collaboration with the Fraunhofer Institute, has developed a new method to analyse hereditary hair loss in men.

In collaboration with the Fraunhofer Institute, Dr. Wolff Research has now taken a systemic approach to hair loss* and conducted a comprehensive analysis of the human scalp.

Whereas previous studies examined areas with only around 300 hairs, our new method, which evaluates more than 10.000 hairs per head, provides precise results:

The combination of caffeine and DMG can effectively reduce hair loss*. And in some cases, new hair growth** was even observed.

FAQ: Answers to your questions

You can easily combine the Caffeine DMG Shampoo and the Caffeine DMG Serum, but it's not absolutely necessary to use both products at the same time.

What's crucial is that your hair and scalp receive a daily dose of Caffeine DMG.

We recommend using the shampoo on days when you wash your hair and the serum on days when you don't.

Already after 3 months of regular use, clinical studies have shown a significant reduction in hereditary hair loss.

As a scientifically oriented company, Dr. Wolff places the highest value on sound research and evidence-based statements. We are currently a pioneer in the field of topical application of N,N-dimethylglycine (DMG). To generate valid and objective data, we rely on a high-quality study design. Our investigations – for example into the Alpecin Caffeine-DMG products – were therefore conducted in a placebo-controlled, randomised, and double-blind manner. A brief explanation of these terms:

  • Placebo-controlled: One group receives the active ingredient formulation, another receives a placebo. This allows the actual effectiveness to be assessed objectively.
  • Randomised: Allocation to the groups is made at random in order to avoid systematic bias.
  • Double-blind: Neither the study participants nor the technical staff know who is receiving which treatment, ensuring unbiased results.
