What is the mechanism of action of coal tar in dandruff treatment?

Coal tar is used in dandruff treatment primarily for its anti-inflammatory, anti-fungal, and keratolytic properties. It works by slowing down the rapid growth of skin cells on the scalp, which helps reduce flaking and scaling associated with dandruff. Additionally, coal tar has antimicrobial effects that can help control the overgrowth of yeast, a common contributor to dandruff. Its soothing properties also alleviate itching and irritation.
