Anti-dandruff shampoos often contain active ingredients such as zinc pyrithione, coal tar, or salicylic acid, which can cause a burning sensation on the skin. These ingredients are designed to treat dandruff by exfoliating the scalp and reducing the production of skin cells. However, they can also irritate the skin, especially if left on for too long or if the skin is sensitive. It's important to follow the instructions on the shampoo and to rinse thoroughly to minimize any discomfort. **

This can be a sign that the product is effectively clearing out the pores and addressing the root cause of the acne. However, if the worsening of the skin persists for an extended period of time, it may be a sign that the product is not suitable for the individual's skin and a different approach may be necessary. **
