How Long Does It Take For Dandruff Shampoo to Work?

Dandruff shampoos typically begin to show results within a few days to two weeks, depending on the severity of the condition and the active ingredients used. Most people notice reduced flaking and itching after 3 to 7 uses when applied regularly—usually 2 to 3 times a week. However, for more stubborn dandruff or scalp conditions like seborrheic dermatitis, it may take up to a month of consistent use to see significant improvement. It's important to follow the product instructions carefully and be patient, as long-term control often requires continued, routine use even after symptoms improve.
