Overview
Alpecin C1 Caffeine Shampoo is the original and most established product in the Alpecin range — a daily cleansing shampoo that delivers caffeine to the scalp and hair roots during every wash. The C1 formula is the result of Alpecin's research into the role of caffeine in counteracting the effects of testosterone on hair follicles, which is the primary mechanism of androgenetic (hereditary) hair loss — the most common form of hair loss in men.
Used daily as a straight replacement for regular shampoo, the C1 cleanses the hair and scalp while delivering caffeine at every wash — making consistent caffeine scalp care straightforward to maintain without any additional steps in the routine.

What It Does
- Delivers caffeine to the hair roots during every wash. The C1 formula is designed to penetrate the scalp during the washing process — research by Alpecin indicates that caffeine reaches the hair follicles within two minutes of contact, making it important to leave the shampoo on the scalp for at least two minutes before rinsing.
- Counteracts DHT activity at the hair follicle. Caffeine has been shown in research to counteract the inhibitory effect of DHT (dihydrotestosterone) on hair follicle growth — the biochemical driver of androgenetic hair loss in men — helping to support follicle activity and prolong the active growth phase of the hair cycle.
- Cleanses the scalp and hair effectively. Beyond the caffeine benefit, C1 is a fully functional daily shampoo that removes oil, sweat, and product build-up from the scalp and hair, leaving it clean and refreshed after every wash.
How to Apply
- Use daily as your regular shampoo. Replace your current shampoo with Alpecin C1 for daily use — consistency is essential for caffeine-based hair care to be effective.
- Wet the hair thoroughly and apply a generous amount. Work the shampoo into a lather at the roots and scalp, ensuring good coverage across the whole scalp.
- Leave on the scalp for at least two minutes. This is critical — research indicates that caffeine needs approximately two minutes of scalp contact time to penetrate the follicles effectively. Do not rinse off immediately.
- Rinse thoroughly. After the two-minute contact time, rinse the hair completely.
- Use daily without exception. The caffeine benefit requires consistent, uninterrupted daily use — occasional use will not deliver meaningful results.
Note: Alpecin C1 Caffeine Shampoo is designed for men experiencing hereditary hair thinning. It is a supportive scalp care product, not a licensed medical treatment for hair loss. Consult your GP or dermatologist if hair loss is sudden, significant, or patchy.
Who It's For
- Men with hereditary hair thinning or early androgenetic hair loss — the primary target for Alpecin's caffeine research and the most appropriate user for this product.
- Men who want a proactive, daily approach to scalp and hair root care — replacing an existing shampoo with C1 requires no additional steps in the routine, making it a low-effort, consistent way to deliver daily caffeine to the scalp.
- Those in the early stages of hair thinning who want to support hair follicle activity before loss becomes more significant — preventive use is one of the most common and effective applications of caffeine shampoo.
Good to Know
- Leave on for two minutes — this is non-negotiable for results. The two-minute contact time is the single most important application instruction for Alpecin C1. Rinsing immediately removes the caffeine before it can penetrate the scalp effectively.
- Daily use is essential. Caffeine-based hair care works through consistent, cumulative daily delivery of caffeine to the follicles. Skipping days or using the shampoo infrequently will significantly reduce the benefit.
- Results require long-term commitment. Three to six months of daily consistent use is the minimum period for assessing meaningful results — hair growth cycles are slow and require sustained support to show visible change.

FAQs
How does caffeine shampoo help with hair loss?
Alpecin's research has shown that caffeine penetrates the scalp during washing and directly stimulates the cells of the hair follicle. In the context of androgenetic (hereditary) hair loss, DHT — a testosterone derivative — binds to hair follicle receptors and progressively shortens the active growth phase of the hair cycle, leading to thinner, shorter hairs and eventual follicle dormancy. Caffeine has been shown to counteract this DHT-driven inhibition, helping to maintain follicle activity and prolong the growth phase with consistent daily use.
Why do I need to leave the shampoo on for two minutes?
Research by Alpecin indicates that caffeine requires approximately two minutes of scalp contact time to penetrate the follicles effectively. If the shampoo is rinsed off immediately after application — as many people do with a standard shampoo — the caffeine does not have sufficient contact time to penetrate the scalp before being washed away. Leaving the shampoo on the scalp for two minutes before rinsing is the single most important step for getting the caffeine benefit from the product.
Can I use Alpecin C1 alongside the Caffeine Liquid?
Yes — using both products together is the approach Alpecin recommends for the most comprehensive caffeine delivery to the scalp. The shampoo provides caffeine during washing with the two-minute contact time; the leave-on liquid extends caffeine exposure further by remaining on the scalp throughout the day. Together, they provide the widest possible caffeine coverage for the follicles.
How long before I see results from Alpecin C1?
Alpecin recommends a minimum of three months of consistent daily use before assessing results — hair growth cycles are measured in months, and supporting follicle activity requires sustained, long-term caffeine delivery to show a meaningful visible impact. Some users report improvement in hair feel and condition earlier, but assessing whether the treatment is having a meaningful effect on hair loss requires a longer evaluation period.
Is Alpecin C1 suitable for women?
Alpecin C1 is developed and marketed specifically for male androgenetic hair loss, which is driven by DHT sensitivity in the follicles. Female hair loss has different underlying causes and patterns in most cases, and Alpecin's product development and research is focused on the male hair loss mechanism. Women experiencing hair thinning should consult their GP or a dermatologist for appropriate assessment and product recommendations.
Can I use this shampoo every day without damaging my hair?
Yes — Alpecin C1 is formulated for daily use and is the recommended usage frequency. The shampoo is designed to cleanse effectively without over-stripping the scalp, and daily use is an intended and supported part of the product's instructions. Some men find their scalp adjusts during the first week or two of daily washing — any initial changes in scalp oiliness typically settle as the scalp adapts to the routine.
