Quick overview

Alpecin Shampoo is a cosmetic caffeine-based hair care product aimed at men, designed to fight dandruff and help reduce hair loss. It works by loosening dandruff from the scalp so that caffeine can penetrate the hair roots during washing. The shampoo is intended for regular use, typically daily, as part of a hair care routine.

What is Alpecin Shampoo

Alpecin is a caffeine-based hair care shampoo brand aimed at men, designed to fight dandruff and help reduce hair loss.

Alpecin Shampoo uses

  • Against dandruff and hair loss
  • Combating dandruff-causing fungus on the scalp
  • Helping with dry, itchy, or red scalps

Benefits of Alpecin Shampoo

  • Helps cleanse the scalp and hair effectively.
  • Caffeine-containing formulas are designed to help strengthen thinning hair.
  • Can help hair feel thicker, fuller, and stronger with regular use.
  • Contains ingredients such as caffeine, zinc, and niacin that support healthy-looking hair and scalp.
  • May help support hair-root activity and maintain natural hair growth.
  • Is particularly marketed for men experiencing thinning or hereditary hair loss.

How Alpecin Shampoo works

The shampoo first loosens and removes dandruff from the scalp, which then allows caffeine to penetrate into the hair roots during washing. The caffeine forms a 24-hour depot in the hair root, which may help protect it from becoming inactive too soon.

Alpecin Shampoo dosage

Wet your hair, apply the shampoo evenly, and massage it into the scalp. Leave the shampoo on the hair and scalp for about two minutes before rinsing thoroughly. It can be used daily for best results. One liquid (non-shampoo) product is applied to towel-dried hair and not rinsed out; avoid contact with eyes.

Side effects of Alpecin Shampoo

Common

  • Scalp irritation, itching, and redness
  • Allergic reaction to caffeine
  • Discolouration or browning of hair with long-term use
  • Possible reduction in results over long periods of use

Serious

  • Increased heart rate and blood pressure from caffeine absorbed through the skin
  • Narrowing of blood vessels (vasoconstriction), which may increase blood pressure and the risk of coronary artery disease

Warnings and precautions

  • Avoid getting the leave-in caffeine liquid product in your eyes.
  • Because it contains caffeine, use during pregnancy only after checking with a doctor or pharmacist, especially with frequent use. Keep total caffeine exposure within recommended pregnancy limits.
