What should you know about growing a bald spot back?

A smooth, sharply defined patch can be a presentation of alopecia areata, an immune-mediated condition that may affect one or several areas. A scaly, tender, crusted, or broken-hair patch can be a presentation of scalp ringworm, which requires prescription treatment and should not be managed with steroid cream alone.

Hair pulling, inflammation, injury, and other scalp disorders can also create a bare area. A clinician checks the patch, nearby hairs, skin surface, and other body sites. The pattern, speed of change, itch, scale, and tenderness help guide the next step.

Arrange a dermatology assessment, especially if the patch is enlarging or new patches appear. Avoid tight styles, picking, harsh chemicals, and sharing combs, hats, or pillows until infection has been considered. Take a clear photograph and note when the area first changed.

Treatment may include targeted anti-inflammatory medicine for alopecia areata or antifungal medicine for scalp ringworm. A hair transplant is a restoration procedure, not a substitute for treating active infection or inflammation; it is considered only after the cause and stability have been assessed.

Seek prompt care for scalp pain, pus, spreading redness, fever, swollen glands, marked crusting, or a patch that expands quickly. Arrange earlier review for eyebrow or eyelash loss, nail changes, or smooth shiny skin, which may signal a broader or scarring process.

Does the patch look smooth and non-scarring, or is there infection or inflammation? Do I need a fungal test? Which treatment is appropriate, and how long should we monitor before discussing restoration?
