Active Ingredients

• Caffeine — The star active ingredient. Inhibits the breakdown of intracellular messenger cAMP in hair follicle cells, increasing energy availability and stimulating cell growth. Counteracts DHT effects on hair follicles, the primary cause of hereditary hair loss. Penetrates hair follicles within 2 minutes and remains detectable for up to 24 hours. Backed by over 20 years of research.
• Zinc PCA — Regulates sebum production on the scalp, reduces oiliness, and supports a healthy scalp environment conducive to hair growth. Works synergistically with caffeine as part of the patented Caffeine Complex.
• Niacinamide (Vitamin B3) — Improves microcirculation in the scalp, enhancing nutrient delivery to hair follicles. Supports the overall effectiveness of the Caffeine Complex and contributes to healthier, stronger hair growth.
• Panthenol (Pro-Vitamin B5) — Penetrates the hair shaft to moisturize from within, improving hair flexibility, reducing breakage, and adding shine. Also soothes the scalp.
• Hydrolyzed Wheat Protein — Strengthens the hair shaft by filling in damaged areas, reducing breakage and improving overall hair texture and manageability.
• Tocopherol (Vitamin E) — Protects hair follicles and scalp from oxidative stress and free radical damage, supporting a healthy environment for hair growth.

How to Use

1. Apply to wet hair — Wet your hair thoroughly with warm water. Apply a sufficient amount of Alpecin Caffeine Shampoo C1 to your hair and scalp.
2. Massage into scalp — Massage the shampoo thoroughly into your hair and scalp, ensuring even distribution across the entire scalp area.
3. Leave on for 2 minutes — Leave the shampoo on your hair and scalp for at least 2 minutes. This is essential to allow caffeine to penetrate the hair follicles. Do not rinse off before 2 minutes have elapsed.
4. Rinse thoroughly — Rinse thoroughly with water after the 2-minute contact time.
5. Use continuously — For best results, use daily and continue use for at least 3 months. If hair requires less frequent washing, use the Alpecin After Shampoo Liquid Scalp Tonic in between shampoos to maintain caffeine supply.

Usage frequency: Once daily. Consistent daily use is essential for optimal results.
