What should you know about hair product to cover bald spots?

Cover products work by adding colour, texture, or visual density to the hair and scalp. Fibres often grip existing hair, while powders and sprays can shade visible scalp; their effect usually changes with washing, sweating, or rubbing. They cannot regrow hair or prevent an active scalp condition. New smooth patches, broken hairs, scale, or itch may point to a condition such as alopecia areata or scalp ringworm, so concealment should not delay diagnosis.

Choose a shade that blends with your hair and test a small area first, particularly if your skin reacts easily. Apply to clean, dry hair and follow the product directions. Remove it before sleep and stop if burning, rash, swelling, or worsening itch develops. Avoid sharing applicators, brushes, or caps. Use gentle handling around a bare patch and avoid tight hairstyles that pull on nearby hairs. Photographing the area before covering it can help you notice change and show a clinician.

Arrange an assessment for a bald spot that is enlarging, recurring, or accompanied by scale, broken hairs, redness, tenderness, or pus. Seek prompt care for painful swelling, fever, or rapidly spreading inflammation. A clinician can examine the scalp before recommending medical treatment or a hair-restoration option.

Ask what could be causing the patch, whether the scalp needs testing, which products are least irritating, and whether treatment should begin before considering a hair transplant.
