- Follow the instructions on the dandruff shampoo bottle. For example, some dandruff shampoos require that you lather the shampoo into the hair and scalp and leave the shampoo in for about five minutes before rinsing. Others should not be left on the scalp.
- If you are Caucasian or Asian, shampoo daily and use dandruff shampoo twice a week. If using one dandruff shampoo does not bring relief, try alternating between dandruff shampoos with different active ingredients.
- If you are African-American, only shampoo once a week using a dandruff shampoo.
- Be careful when using a dandruff shampoo that contains coal tar. Tar shampoo can discolor blonde, grey or white hair, so if you have light-colored hair, you may want to choose a different dandruff shampoo. Tar shampoo also has the potential to make your scalp more sensitive to sunlight. If you use this type of dandruff shampoo, it’s important to protect your scalp from the sun by wearing a hat when outdoors and seeking shade whenever possible.
Sometimes, dandruff is a sign of a medical condition such as seborrheic dermatitis, psoriasis, fungal infections of the scalp, or eczema. Contact your clinician if the above tips do not help your skin condition.
