Dark spots on the scalp: what to know

Pigment may remain after folliculitis, scratching, eczema, a pimple, or another scalp irritation. Sun exposure can affect a thinning or uncovered scalp, while some fungal conditions can alter skin colour and texture. Hair can hide changes, so ask someone to check the area or use a clear photograph. A dermatologist may examine the surface and surrounding follicles to tell a flat pigment mark from scale, a mole, or a raised lesion.

Avoid picking, harsh oils, and strong bleaching products on the scalp. Treat itching or flaking only with advice suited to the diagnosis, and protect exposed scalp with a hat or sunscreen that does not irritate it. If pigment remains after inflammation has settled, a dermatologist may consider [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), a carefully selected [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), or [Picosecond Laser Treatment](/treatments/laser-and-energy/picosecond-laser-treatment/). These options are not interchangeable, especially when hair follicles are inflamed or the diagnosis is uncertain.

Book an assessment for a spot that grows, develops irregular edges, changes colour, crusts, bleeds, hurts, or forms a persistent sore. Prompt review is also sensible when several marks appear with marked itch, scale, or hair loss. Learn more about [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) and [Tinea Versicolor](/conditions/tinea-versicolor/) if colour change occurs with surface scale.

Is the spot pigment left by inflammation, or does it need a closer examination? Could a shampoo, hair dye, or treatment be irritating the scalp? Should I treat flaking first, and which pigment treatment is least likely to irritate my follicles?
