QUESTION

How often should I wash an oily scalp?

Wash often enough to control oil and buildup without making your hair-care routine unnecessarily harsh. Dermatology guidance notes that people with fine or straight hair and an oily scalp may need frequent or even daily shampooing.

DIRECT ANSWER

What to know

Use oiliness as a practical signal — The AAD recommends washing based on how often hair becomes dirty or oily. For some people with fine or straight hair and an oily scalp, daily shampooing may be reasonable; other hair textures may need a different schedule.

Focus shampoo on the scalp — Apply shampoo primarily to the scalp, where oil, dead skin and product buildup accumulate. Let the rinse move through the lengths rather than aggressively rubbing fragile hair.

Adjust if your scalp or hair disagrees — Frequency is not a fixed rule. Increase or reduce washing based on oiliness, dryness, irritation, flakes, hair texture and product tolerance. Persistent scalp symptoms can warrant dermatology advice.

IMPORTANT LIMITS

Frequency should be adjusted for hair texture, scalp conditions, product tolerance and clinician guidance when a medical scalp disorder is present.

Breakage can coexist with shedding or a medical cause of hair loss, so appearance alone does not establish the cause.
