What should you know about shampoos for dry flaky scalp?

A dry scalp can flake after cold, dry weather, frequent heat styling, harsh cleansing or product irritation. Dandruff and seborrheic dermatitis can also create flakes, sometimes with itch or redness. Scalp psoriasis may produce thicker, well-defined plaques, while scalp ringworm can cause scale with broken hairs or patchy hair loss.

Because these conditions can look similar at first, a shampoo that moisturises or loosens scale may soothe the surface without treating the underlying problem. Notice whether the flakes are fine or thick, whether the scalp is red, and whether hair changes are present.

Use lukewarm water and a mild, fragrance-free cleanser when possible. Massage with fingertips, rinse fully, and avoid scratching or lifting attached scale with the nails. Limit products that sting and apply conditioner to the hair lengths rather than the scalp if it worsens buildup. If a medicated shampoo is recommended, follow its directions closely and give it contact time as instructed.

Book a medical review when flaking lasts despite gentle care, repeatedly returns, or forms thick plaques. Seek prompt advice for tenderness, pus, spreading redness, bleeding, swollen glands, or patchy hair loss. Children with scalp scaling and hair loss should be assessed for scalp ringworm rather than treated only with cosmetic shampoo.

Ask which cause best fits the pattern, whether you need a medicated shampoo, how long to try it, and which hair products should be paused while the scalp settles.
