What should you know about oily hair and scalp?

Oil is produced by glands around hair follicles. The amount and speed of buildup vary with skin type, hormones, heat, exercise, hair texture and product use. Oily roots alone are a symptom, not a diagnosis. When oil sits with scale and itch, dandruff or seborrheic dermatitis may be involved. Redness, burning or spots after a new product can instead suggest irritation or contact dermatitis. Looking at the scalp, not only the hair, helps distinguish simple oiliness from an inflamed condition.

Cleanse the scalp with a mild shampoo as needed for comfort and oil control, using fingertips rather than nails. Rinse thoroughly and keep heavy oils, waxes and leave-in products away from the roots if they worsen buildup. Wash brushes regularly and avoid repeatedly touching the scalp. If flakes or itch accompany oiliness, a medicated shampoo may be useful when selected and used according to professional advice. Give a new routine time to show whether the scalp is calmer before adding several products.

See a dermatologist if oiliness is accompanied by persistent itch, redness, thick scale, pain, sores, discharge or hair shedding. Seek earlier advice when symptoms began after a new dye, treatment or styling product, or when the scalp is affecting sleep and daily comfort. A clinician can examine the skin and recommend treatment matched to the cause.

Ask what washing frequency suits your scalp, whether the pattern suggests dandruff or seborrheic dermatitis, and whether a medicated shampoo is appropriate. Share your products, wash routine and any symptoms on the face, ears or chest.
