What should you know about oily scalp care?

Sebum is produced at the scalp surface and can build up between washes, especially with heat, exercise, hats or rich styling products. An oily scalp may feel greasy soon after washing, but the hair lengths can still be dry because oil does not travel evenly along every strand.

Itching or visible scale may indicate dandruff. Greasy scale with redness around the hairline, ears or eyebrows can occur with seborrhoeic dermatitis. These patterns need more than simply washing harder.

Use a gentle shampoo on the scalp and massage with fingertips, not nails. Rinse well, then place conditioner mainly through the mid-lengths and ends. Clean brushes regularly and avoid applying thick oils, waxes or leave-in products directly to the roots if they increase buildup.

If flakes or itch persist, a medicated shampoo treatment may be suitable. Follow its directions carefully, including how long it stays on the scalp, and stop or seek advice if it causes significant irritation. Adjust wash frequency to comfort, activity and oil production rather than following a fixed rule.

Arrange medical review for persistent itch, painful spots, thick scale, bleeding from scratching, oozing or patchy hair loss. A dermatologist can distinguish dandruff from psoriasis, infection, contact irritation or seborrhoeic dermatitis when routine care is not enough.

How often should I wash my scalp? Is my flaking consistent with dandruff or seborrhoeic dermatitis? Would medicated shampoo treatment help, and how can I protect dry hair lengths while treating the roots?
