THE DOCTOR hair mask with tar and ichthyol is a cosmetic mask designed for use on the scalp as well as the lengths of the hair. It falls into the anti-dandruff category, but it is a care product rather than a medical treatment. It is usually chosen when the scalp becomes oily quickly, when flakes are noticeable, or when the roots feel heavy while the hair itself should remain soft and protected.
The formula is built around three actives: tar, ichthyol and the Sebo-stop complex. Tar is valued in hair and scalp cosmetics because it helps reduce the look of excess oil and visible flaking, and it can leave the scalp feeling cleaner for longer. Ichthyol is known for soothing properties and is often included in products aimed at scalp balance. The Sebo-stop complex targets oily scalp concerns and weakened-looking hair, helping to improve the condition of the scalp surface and supporting hair along the length.
In practice, the mask is intended to address the scalp surface and support the hair at the same time. Instead of relying only on heavy conditioning agents, it aims to reduce buildup at the roots and make hair easier to manage after washing. The 946 ml jar is suited to regular bathroom use, including use by several people or by someone who washes hair often.
