What should you know about lichen planus scalp?

Scalp involvement may look like red or purple bumps, fine scale, crust, or areas of tenderness and burning. You might notice increased shedding, broken hairs, or smooth patches where hair looks thinner. Itch is possible but not required. Similar symptoms can come from several scalp disorders, so colour and flaking alone cannot confirm the diagnosis. Read about [Lichen Planus](/conditions/lichen-planus/) and related [Skin Bumps](/symptoms/skin-bumps/).

Book a dermatology assessment for ongoing soreness, scale, bumps, or patchy hair change. Until then, wash gently, avoid scratching, and pause tight hairstyles, extensions, bleaching, relaxing, and strongly fragranced products. Photograph the scalp periodically without changing the lighting, so progression is easier to discuss. Depending on the examination, a clinician may recommend [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) or another anti-inflammatory plan; extensive inflammation may prompt discussion of [Oral Corticosteroid Treatment](/treatments/medical-dermatology/oral-corticosteroid-therapy/).

Seek prompt assessment if hair loss is advancing, the scalp is painful, or there is pus, bleeding, thick crust, or marked redness. Get urgent help for a severe allergic reaction, facial swelling, breathing difficulty, or widespread blistering. Early review is especially useful when smooth areas are appearing, because the clinician needs to distinguish active follicle inflammation from other types of hair loss.

Could this be scalp lichen planus or another scalp condition? Are the follicles inflamed or scarred? Would a biopsy or hair-focused examination help? Which products and hairstyles should I avoid while treatment begins?
