For scalp psoriasis with itching, patches, and dandruff, you can use medicated shampoos containing coal tar, salicylic acid, or ketoconazole to reduce flakes and itching. Avoid scratching, keep your scalp clean, and gently massage oils if recommended. Consult a dermatologist for the right medicine and management plan.

During pregnancy, you can use mild, pregnancy-safe anti-dandruff shampoos containing zinc pyrithione or ketoconazole to control flakes. Avoid strong chemical treatments. For hair loss, focus on gentle hair care, a healthy diet, and avoiding tight hairstyles. Always check with your doctor before starting any new hair treatment to ensure it is safe for you and your baby.
