Medicasp Shampoo goes to work on the scalp with an OTC medicated formula that helps normalize fast cell turnover and calm irritation—making the itch–flake cycle easier to manage, even when Malassezia may be part of the picture. In real-world use, many people notice improvement early in their routine; keep using as directed for best results.

What is coal tar?

A trusted scalp treatment used for over 200 years, coal tar is an OTC ingredient that helps control dandruff symptoms like flaking and irritation and supports long-lasting scalp comfort when used regularly.

Medicasp uses a coal tar extract designed to work at the scalp surface, helping reduce visible flakes and soothe itchy, irritated skin—so hair looks clearer and feels more manageable.

How to use for best results

Apply to wet hair and gently massage into the scalp. Leave on a few minutes, then rinse thoroughly; repeat if desired. Use 2–3× per week (or as directed by your doctor). If symptoms persist or worsen, stop use and ask a healthcare professional.
