Salicylic acid is well-regarded for its effectiveness in treating dandruff and other scalp issues. It is a keratolytic agent, which means it helps to break down the outer layer of the skin and promote the shedding of dead skin cells. This reduces the buildup that can contribute to dandruff and can also help alleviate associated itching and flaking. Salicylic acid works by exfoliating the scalp thoroughly, therefore providing relief from inflammation and aiding in the overall health of the scalp.

While peppermint oil, argan oil, and lavender extract may offer various benefits—such as soothing the scalp, providing hydration, or promoting relaxation—they do not specifically target the underlying causes of dandruff as effectively as salicylic acid does. Each of these other substances has its merits, but when it comes to treating dandruff or scalp-related issues directly, salicylic acid is the most effective choice.
