What should you know about hypopigmentation on the forehead?

The forehead is exposed to sunlight, sweat, hair products, and friction from hats or headwear. A dry or itchy patch may follow eczema or irritation. Fine scale can occur with tinea versicolor, while a smooth, sharply lighter area may need assessment for other pigment conditions. The appearance alone cannot establish the cause.

Note when it began, whether it changes after sun exposure, and whether the hairline, eyebrows, or nearby skin is involved. [White Patches On Skin](/symptoms/white-patches-on-skin/) offers a useful symptom guide; [Atopic Dermatitis](/conditions/atopic-dermatitis/) covers eczema patterns.

Wash gently, moisturise, and avoid rubbing the forehead or applying fragranced oils, harsh exfoliants, or unprescribed combination creams. Review hair and skincare products introduced before the patch appeared. Use sun protection and a hat that does not rub the area, since tanning nearby skin can make the patch stand out.

Arrange an assessment if the patch grows, becomes scaly, or remains unexplained. Treatment may involve managing eczema or infection; selected patients may be offered topical calcineurin inhibitors or excimer laser therapy after a clinician confirms the diagnosis.

Seek prompt review for rapid expansion, pain, marked swelling, blisters, ulcers, bleeding, pus, fever, eye symptoms, or altered sensation. A patch that changes texture or repeatedly returns despite removing irritation should be examined rather than repeatedly treated at home.

Ask whether the patch is linked to eczema, irritation, infection, or another pigment change; whether its scale or border needs testing; and which products are safe near the hairline and eyes. Ask how to monitor it and when follow-up is needed.
