Description
Alpecin Double Effect Caffeine Shampoo is a shampoo containing caffeine, marketed for a flaking scalp. It is massaged into wet hair and worked onto the scalp itself, and the manufacturer advises leaving it in contact with the scalp for a period before rinsing so the ingredients have time to act. It is used as a regular routine rather than as a short course.
A shampoo is in contact with the scalp only briefly, and hair thinning has many causes, including pattern hair loss, thyroid disorders and iron deficiency, none of which a shampoo addresses. Anyone concerned about hair thinning, or with a sore, weeping scalp or hair loss in patches, should see a pharmacist or doctor.
