DMG: Turning point in hair loss* research

Dimethylglycine (DMG) promotes microcirculation in the scalp, ensuring the hair roots are supplied with nutrients again.

Blood supply to the smallest blood vessels (microcirculation)

Thanks to decades of research, it's known that caffeine boosts hair root activity and extends the growth phase of hair roots.

The new active ingredient, Dimethylglycine (DMG), was previously completely unknown in dermatological research. Studies show that DMG increases microcirculation, meaning it enhances the blood supply to the smallest blood vessels, thereby improving the nutrient supply to the hair roots.

Caffeine and DMG support the nutrient supply and activity of the hair roots. These two effects are particularly important when the hair follicle is weakened.

A clinical study shows that the patented combination of caffeine and DMG effectively reduces hereditary hair loss and can even increase hair growth**.

  • Clinical study: 92 %

    of users had a clinically proven reduction in hair loss*

    A double-blind, randomized, placebo-controlled study involving 154 men with hereditary hair loss, who used either the new Caffeine + DMG shampoo or a placebo shampoo daily over a period of 6 months.

Hair growth* can be increased
