Effectiveness of medicated shampoo against hair loss

The document from 6 years ago discussed the chronic scalp condition, dandruff, which is characterized by white flakes of dead skin cells that cause itching and can lead to hair fall. The study aimed to evaluate the effectiveness of medicated shampoos against hair loss. These shampoos often contain ingredients such as zinc pyrithione, ketoconazole, coal tar, selenium sulfide, and salicylic acid. These ingredients target fungus and bacteria, slow the growth and die-off of skin cells on the scalp, and loosen flakes so they can be washed away, respectively. The document did not provide the results of the study or the number of participants involved.
