Alpecin Caffeine Shampoo Daily Cleanse 8.45 fl oz — Zinc & Niacin for Thicker, Stronger Hair

Alpecin C1 Caffeine Shampoo is a daily shampoo formulated with caffeine, zinc and niacin to cleanse the scalp and support a fuller-looking head of hair.

This concentrated 8.45 fl oz bottle uses a targeted formulation developed in Germany to deliver caffeine and supportive nutrients into the hair shaft and scalp. The lightweight gel lathers to remove dirt, oil and styling residue while leaving strands feeling stronger and more resilient. Alpecin emphasizes routine use: the shampoo is designed for everyday application so the active ingredients can continuously work at the scalp surface and hair roots.

How does this shampoo fit into a daily routine?

Use Alpecin C1 as your regular cleansing step: apply to wet hair, massage into the scalp for about two minutes, and rinse. Regular application keeps the scalp clean and allows caffeine and co-actives to remain present between washes.

• Suitable for daily washing on short to medium hair lengths
• Massage for 1–2 minutes to maximize scalp contact
• Rinse thoroughly and repeat if needed for heavy styling buildup

What active ingredients are included and what do they do?

The formula combines caffeine with zinc and niacin (vitamin B3) plus castor oil to nourish and fortify hair fibers. These ingredients are chosen to enhance strand resilience and improve the hair's appearance by supporting thicker-feeling texture.

• Caffeine: formulated to penetrate hair shafts and contact the scalp surface
• Zinc and niacin: contribute to scalp and fiber condition
• Castor oil: adds moisturizing support for strand flexibility

Will this shampoo change the look and feel of my hair quickly?

Visible texture changes can appear after several washes as residue is removed and strands regain body. For sustained improvement in thickness perception, consistent use over weeks is typical; results vary by individual hair type and habits.

• Immediate: cleaner scalp and reduced product buildup
• Short term: hair usually feels fuller and firmer after multiple washes
• Longer term: continued use helps maintain thicker-feeling appearance

Is Alpecin C1 suitable for colored or treated hair?

The gentle gel format cleans without heavy detergents, making it generally compatible with color-treated or chemically processed hair. If you have a sensitive scalp or unique treatment, perform a patch test or consult your stylist.

• Compatible with most color and styling treatments
• Avoid if you experience irritation; discontinue use and seek advice
• Pair with a conditioner if your hair needs extra moisture

Who is this for: Alpecin C1 is aimed at people seeking a daily, energizing shampoo that focuses on scalp cleansing and thicker-feeling hair texture. It's well suited to men and women with thinning or fine hair who prefer a routine cleanser with targeted actives and German-formulated reliability. If you want a straightforward shampoo to reduce buildup and impart fuller-feeling strands as part of a consistent care routine, this product is made to integrate easily into daily grooming.
