Products to cover bald spots: what to know

Hair fibres, scalp powders, tinted sprays, and partial hairpieces can reduce the contrast between the scalp and surrounding hair. They work best when some surrounding hair can hold the product. Sweat, friction, and scalp oils may loosen coverage. A bald patch can result from alopecia areata, infection, traction, or other causes, and each needs a different approach.

Choose a product intended for scalp use, apply it to clean dry hair, and remove it before sleep if the label advises. Avoid sharing applicators, especially when the scalp is scaly or inflamed. Do not place fibres over broken skin. Take occasional photos in the same lighting so changes are visible, and arrange assessment before considering longer-term restoration such as a hair transplant.

Book a medical review for sudden or expanding patches, scalp pain, redness, pus, marked scale, broken hairs, or loss of eyebrows or eyelashes. Scalp ringworm can require prescription treatment and may spread to others, so covering it should never replace examination.

Ask what pattern of hair loss you have, whether the scalp needs testing, which products are safe on it, and whether treatment could help regrowth. Ask how to care for the scalp while waiting for improvement.
