Frequent washing also removes excess oil, reduces odor, and minimizes irritation from environmental factors or hair products. Contrary to a common myth, washing often does not make the scalp produce more oil. Skipping washes for too long can lead to itching, flaking, tenderness, or a greasy look, particularly in warm climates or for active individuals.
The best routine is one that keeps the scalp clean and comfortable without over-drying. Dermatologists stress listening to your hair and scalp, adjusting frequency as needed for personal comfort.
