What should you know about lichen planopilaris LPP?

LPP belongs to a group of conditions in which inflammation surrounds and injures the upper part of a hair follicle. People may notice itching, burning, tenderness, redness, scale, or hairs that seem to thin in patches. Some areas become smooth or shiny as scar tissue replaces follicles. LPP can be active even when discomfort is mild, which is why a clinician looks at the scalp pattern and the follicle openings rather than judging by shedding alone. A biopsy may be considered when the findings are unclear.

Arrange a dermatology assessment and bring a list of symptoms, products, medicines, and the date you first noticed change. The plan may involve topical anti-inflammatory care, injections into active patches, or tablets when inflammation is broader. Information about [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) and [Oral Corticosteroid Treatment](/treatments/medical-dermatology/oral-corticosteroid-therapy/) can help you prepare for that conversation. Use gentle hair care meanwhile and avoid traction or procedures on an irritated scalp.

Contact a dermatologist if thinning is advancing, new sore or scaly patches appear, or the scalp becomes increasingly red, tender, or itchy. Get urgent medical help for fever, pus, rapidly spreading redness, sudden swelling, or severe pain, since these may point to infection or a different acute problem.

Ask how active the LPP appears, whether scarring is present, what improvement would look like, and how often your scalp should be checked. Discuss medicine interactions and what symptoms should prompt an earlier visit.
