Dandruff is a condition that takes about four to six weeks to get cleared.

Most anti-dandruff shampoos are prescribed for use two or three times a week during active treatment. After that, you can continue them once a week for maintenance.

Lotions with ketoconazole and salicylic acid can cause increased dryness if used daily. The products should only be used as frequently as advised by the doctor.

Using more quantities or applying products more often than prescribed does not make them more effective. It increases the chances of side effects due to overuse.

Lotions for dandruff should not be left on the scalp. They have to be washed off after application to ensure effective treatment. If the product is left on for too long, it can weaken the hair.

Even in the case of continued and regular use of the product, sometimes there may not be a complete response. In these cases, your dermatologist may prescribe an additional product.
