1. Daily Power Up: For best results, use Alpecin C1 Caffeine Shampoo every day.
2. Deeply Nourish: Leave the shampoo on your scalp for 2 minutes. This allows the caffeine complex to penetrate and reach your hair roots directly.
3. Gradual Transformation: While you may notice initial improvements in manageability, it takes about 3 months to see the full effect on hair thickness and strength.

Hair needs a sufficient supply of energy and nutrients to grow properly. When hair follicles are exposed to dihydrotestosterone (DHT), a metabolite of the male sex hormone testosterone, this supply is impaired. As a result, the growth phases of the hair roots are reduced – hair loss and balding are possible results

Alpecin contains Caffeine. Caffeine can counteract this process. Studies prove that caffeine inhibits the negative effects of testosterone on hair growth and balances out the resulting lack of energy. It extends the growth phases of the hair roots back to the normal length so that hair can grow even at an old age.

Yes, Alpecin is also effective and safe for use by women.

While generally well-tolerated, caffeine shampoos may cause:

• Mild Scalp Irritation: For some users, the shampoo might cause temporary itchiness or irritation, especially if it contains parabens. 
• Gradual Hair Darkening: In rare cases, caffeine shampoos might cause hair to appear slightly darker over time.This effect is usually subtle.
• Potential Decreased Effectiveness: Like with many hair products, continued use of caffeine shampoo might lead to a decrease in its perceived effectiveness over time.
