How long does steroid injection into the skin take to work for lichen planopilaris?

Lichen planopilaris is an inflammatory condition affecting hair follicles. The injection delivers medicine to selected active scalp areas, so it is intended to calm inflammation rather than instantly restore hair in an area where follicles have been damaged. Less itch, burning, redness, or scalp tenderness can be an early sign of control. Your clinician may also look for reduced redness around follicles, fewer active symptoms, and whether hair loss is continuing.

Use the scalp care routine recommended by your clinician and avoid scratching or picking active areas. Record changes in itch, burning, pain, scaling, and shedding. Keep scheduled reviews even if symptoms improve, because lichen planopilaris can be active beneath hair and may need treatment adjustments. Protect treated scalp skin as advised, especially if it is exposed to sunlight.

Contact your clinician if scalp pain, redness, scaling, pustules, or hair shedding is increasing. Seek prompt advice for spreading tenderness, marked swelling, or signs of infection. Report a visible dent, skin thinning, or a new light or dark patch where the injection was given, as these local changes need examination.

Ask how active inflammation will be assessed, when progress should be checked, and which symptoms should improve first. Ask what ongoing scalp treatment is needed and how your clinician will distinguish reduced inflammation from permanent follicle damage.
