You can easily combine the Caffeine DMG Shampoo and the Caffeine DMG Serum, but it is not necessary to use both products simultaneously.

What is 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 without hair washing.

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

For a successful anti-hair loss routine, daily and consistent use is highly recommended. Please note the required exposure time of 2 minutes.

For a successful treatment of hereditary hair loss, it's essential to apply Caffeine DMG to the scalp daily. Important: Do not rinse out the serum.

Unlike medicinal products, no undesirable side effects are to be expected with regular use. None were found in studies or reported by consumers so far.

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.
