What should you know about flaky scalp after bleach?

Flaky scalp after bleach often reflects chemical irritation, but dandruff, dermatitis, psoriasis, or infection can also be involved. Bleach can dry or inflame the scalp, especially when it touches the skin or is left on too long. Burning, tenderness, redness, or peeling soon after the appointment supports irritation. Persistent thick scale or hair changes may point to another scalp condition.

A reaction that begins during or shortly after bleaching may be irritant or allergic. Dandruff and Seborrheic Dermatitis can cause recurring flakes with itch and greasy or dry scale, and bleaching may make them more noticeable. Scalp Psoriasis can produce well-defined, thicker scale that extends beyond the hairline. Scalp Ringworm may cause scale with broken hairs or patches of hair loss and needs medical treatment.

Rinse thoroughly with lukewarm water if product remains, and avoid scratching, picking, heat styling, and further chemical treatments until the scalp settles. Use a gentle, fragrance-free shampoo and avoid applying oils or fragranced products to broken skin. If flaking persists, a clinician or pharmacist can advise whether Medicated Shampoo Treatment is appropriate. Keep the product name and timing of the bleach exposure for the appointment.

Get urgent help for facial or eyelid swelling, breathing difficulty, widespread hives, blistering, or severe scalp pain. Arrange prompt review for pus, spreading redness, fever, marked tenderness, or new patches of hair loss. Seek assessment when flakes continue despite stopping bleach, or when the scalp reaction is worsening rather than settling.

Is this a bleach reaction or Dandruff, Seborrheic Dermatitis, Scalp Psoriasis, or Scalp Ringworm? Should I avoid this product or ingredient in future? Is a medicated shampoo suitable? How should I care for the scalp before colouring again?
