How long do you leave Alpecin on for?

Alpecin Caffeine Liquid is massaged into the scalp and left on without rinsing. Alpecin shampoos, such as Caffeine Shampoo C1, should be left on for at least 2 minutes before rinsing. Grey Attack shampoos need 2-5 minutes on the scalp from application to rinsing.

Key points:

• Alpecin Caffeine Liquid absorbs quickly into the scalp after massaging in.
• Shampoos like C1 require at least 2 minutes for caffeine to reach hair roots.
• Grey Attack shampoos work best with 2-5 minutes exposure time.
• Leave-on times can vary by product type and scalp sensitivity.
