What should you know about cure for dry itchy scalp?

Dandruff and seborrheic dermatitis can cause itch with flaking, especially around oily areas. Scalp psoriasis may produce thicker scale and visible plaques. Head lice can cause intense itching and nits attached close to hair shafts, while folliculitis may cause tender bumps around hairs. Hair dye, fragrance, oils, or other products can trigger irritant or allergic inflammation.

Use lukewarm water, a gentle cleanser, and clean hands; avoid scratching because broken skin can become infected. Stop recently introduced products that sting or worsen the itch. If flakes are present, a clinician or pharmacist may guide you to medicated shampoo therapy. If live lice or nits are found, use head lice treatment as directed and follow advice about close contacts and washable items. Avoid applying several active treatments together without guidance.

Seek prompt care for pus, spreading redness, significant swelling, fever, severe pain, or sudden patchy hair loss. Arrange an assessment when itching disrupts sleep, returns repeatedly, follows a new product, or does not improve with appropriate care. A clinician can inspect the scalp and hair rather than assuming every itchy scalp is dandruff.

Can you check for lice, folliculitis, psoriasis, or dermatitis? Which product should I stop? What shampoo or treatment fits the scalp findings? How should I clean combs and bedding if lice are present?
