Really dry, itchy scalp: what it can mean and what to do

Fine flakes after a new product may point to irritation or contact sensitivity. Greasy scale and redness can occur with dandruff or Seborrheic Dermatitis. Thick, sharply defined scale may occur with Scalp Psoriasis. Tender bumps around hairs suggest Folliculitis. Persistent intense itching, visible nits or affected household contacts raises the possibility of Head Lice. A clinician can distinguish these patterns by examining the scalp.

Wash with lukewarm water and a fragrance-free cleanser, rinsing thoroughly. Avoid scratching, tight hairstyles, harsh dyes and fragranced oils while the scalp is irritated. A pharmacist or clinician may recommend Medicated Shampoo Treatment when flaking or inflammation fits that option. Do not share combs, brushes, hats or pillows if lice are possible; confirmed infestation may need Head Lice Treatment. Follow the product directions and stop if burning or swelling develops.

Arrange a medical review if itching lasts despite gentle care, repeatedly disturbs sleep, or comes with spreading redness, pus, painful cracks, bleeding, patchy hair loss or swollen glands. Seek prompt care for facial swelling, breathing difficulty or rapidly worsening pain. These signs can indicate infection, a strong reaction or another condition needing examination.

Could this be Dandruff, Seborrheic Dermatitis, Scalp Psoriasis, Folliculitis or Head Lice? Which cleanser or treatment suits my scalp, and how long should I try it? Could a product, hairstyle or medicine be aggravating the itch?
