Scarring Alopecia: Early Warning Signs
Scarring alopecias destroy hair follicles permanently. Early features include scalp itching, burning, redness, pustules or visible scarring along the hair line. Because the loss is irreversible once scarring is established, early diagnosis genuinely matters. The definitive test is a scalp punch biopsy with histopathology, which our Scarring Alopecia Diagnostic provides in one appointment.
This patient information is being clinically reviewed by our team. The factual content draws on UK guidance (NHS, NICE, British Association of Dermatologists, British Society for Sexual Medicine where cited).
What this might be
- Frontal fibrosing alopecia (FFA). Receding hair line in women, often with loss of eyebrows.
- Lichen planopilaris (LPP). Patches of permanent loss with itching and redness.
- Folliculitis decalvans. Recurrent pustules with hair loss in patches.
- Discoid lupus of the scalp. Round red patches with scarring.
When to seek urgent advice
If any of the following apply, please contact your GP, NHS 111, or A&E in the first instance rather than waiting for private bloodwork.
- Visible loss of the eyebrow tail
- Pustules or persistent redness at the hair line
- Patches that look glossy or smooth (no visible follicles)
- Symptoms progressing over weeks rather than months
Common features that suggest this
- Scalp itching or burning
- Visible redness or pustules
- Hair line moving back unevenly
- Loss of eyebrow tails (FFA)

Testing advice
A scalp punch biopsy under local anaesthetic is the gold-standard test. Same appointment includes histopathology. Bring a list of any medications and supplements you take.
Common questions
How quickly should I act?
If you suspect scarring alopecia, sooner is better. Loss already scarred is permanent; loss not yet scarred can often be preserved.
Will the biopsy leave a visible mark?
It leaves a small scar usually well hidden in surrounding hair. Your clinician will choose the site carefully.
