How it Works: DMG promotes the micro-blood-circulation of the scalp**, and hair loss is effectively reduced*.

Micro-blood-circulation is the foundation for healthy hair growth

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

This is where DMG comes in: its mode of action, comparable to Minoxidil, promotes 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 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 thus one of the most researched active ingredient of plant origin in hair science.

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 supported.

Application: This is the only way to achieve the best result

  • Apply daily

  • Do not rinse out

  • Use continuously

  • Tip - Don’t have time to shampoo your hair?
    Use the Serum on non-wash days.

Effectiveness depends on individual metabolism. 74% of study participants noticed thicker, denser, and fuller-looking hair after 6 months of use.

Measurement method: First-time evaluation of more than 10,000 individual hairs

Focus on a screen showing a close-up of hair to highlight that Dr. Wolff, together 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 systematic 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 new DMG complex is shown to reduce hair loss* and, in some cases, support new hair growth.*"

Clinical study: Hair loss* was reduced in 94% of participants

The graph shows the results of the hair pull test over time, comparing "Caffeine + DMG" with "Placebo." The test group decreases, while the control group increases. The X-axis marks the days, and the Y-axis shows the mean values with confidence intervals.

Double-blind, randomised, and placebo-controlled study:

24-week, randomised, double-blind, placebo-controlled study in 154 men using the serum daily. Participants used either the DMG serum (verum) or a placebo. The primary endpoint—a standardised shedding test —showed fewer hairs shed vs placebo at weeks 12 and 24.

Hair growth can be supported*

Three close-up shots of skin show hair growth at intervals: "Day 0," "Day 84," and "Day 168." Each image displays different hair density on a similar skin surface.

In a study subgroup, hair density increased and more hairs were in the growth phase by Week 12 & 24*:
