Scalp Mole Check — Most Are Harmless, but These Changes Matter
Most scalp moles are harmless. The problem is that they sit under hair, on the back of the head, and out of the mirror — so changes often go unnoticed for months. ScanSkinAI lets you check a mole on your scalp free in your browser (no app, no signup to start) and re-photograph the same spot over the following weeks to monitor any change. It's a screening and monitoring tool, not a diagnosis.
For background on what scalp moles can mean, read the full guide to scalp mole warning signs.
Quick answer
To check a mole on your scalp, part your hair with a comb, photograph the spot under bright light (ideally with help), and run a free browser mole check. Any scalp mole that is bleeding, scabbing, non-healing or new deserves a dermatologist review within 1–2 weeks — scalp melanomas are commonly diagnosed late because hair hides them.

Why a mole on the scalp matters
- Scalp melanomas are diagnosed at later, thicker stages than melanomas elsewhere.
- Hair hides early changes — most scalp lesions are spotted by hairdressers or partners.
- Bald, balding and shaved scalps receive heavy direct UV.
- A bleeding spot, scab that won't heal, or new dark patch on the scalp deserves urgent review.
Hairdressers are an underrated front line for scalp melanoma detection. Ask yours to flag anything new or unusual.
The ABCDE rule for any scalp mole
Dermatologists use the ABCDE checklist to spot suspicious moles. Apply it to any mole on your scalp — and to anything that looks different from your other moles.
A — Asymmetry
One half doesn't match the other.
B — Border
Edges are ragged, blurred or notched.
C — Colour
Mixed shades — brown, black, red, white, blue.
D — Diameter
Larger than 6 mm (pencil-eraser tip).
E — Evolution
Changing in size, shape, colour or sensation.

How to photograph a scalp mole
- Part the hair around the mole with a comb or fingers and use the phone's flash.
- Ask someone else to take the photo — almost impossible to do well alone.
- Mark the location on a body map or diagram so you can find the same spot next time.
- Re-photograph monthly if the lesion is changing; otherwise every 2–3 months is fine.

When to see a dermatologist
Book a clinical exam within 1–4 weeks if a mole on your scalp is:
- • New in adulthood, or genuinely growing
- • Asymmetric, with irregular or blurred borders
- • Multi-coloured or has darkened over weeks
- • Larger than 6 mm
- • Itching, bleeding, crusting or sore
- • Looks different from your other moles ("ugly duckling")
ScanSkinAI is an informational monitoring tool — it cannot diagnose melanoma or any disease. When in doubt, see a doctor.
FAQ — moles on the scalp
Part your hair around the spot, photograph it with your phone (a mirror or a second person helps for the back of the head), and run a free scalp mole check in your browser. Re-photograph the same spot over the following weeks to monitor any change. ScanSkinAI is a screening and monitoring tool — it does not diagnose skin cancer or replace a dermatologist.
Yes. ScanSkinAI runs in your browser with no app to download and no signup to start. It is a first-step screening and monitoring tool, not a diagnosis — see a doctor for any scalp mole that is changing, bleeding, or won't heal.
Most are benign, but scalp melanomas have worse outcomes than melanomas elsewhere because they're often found late. Any changing, bleeding or non-healing scalp lesion needs a dermatologist.
A scalp mole or sore that bleeds, scabs and won't heal needs prompt dermatologist review — within 1–2 weeks. Don't wait for a routine appointment.
Yes. Bald, balding and closely shaved scalps get the same UV exposure per year as your face, without the sun protection hair provides. That means more sun damage, more actinic keratoses, and a materially higher risk of basal cell and squamous cell skin cancers as well as melanoma on the scalp. Wear a broad-brimmed hat outdoors, use SPF 30+ on the scalp, and add a scalp photo to your monthly check.
Shaved scalps make monitoring easier because you can see the whole surface. Once a month, in bright daylight, ask a partner to photograph the top, back and sides of your head, or use a mirror plus your phone's rear camera. Use ScanSkinAI to save each dated photo and compare month-on-month. Any new pigmented spot, growing bump, or scaly patch that keeps returning after healing needs a GP or dermatologist review.
A suspicious scalp mole usually shows one or more ABCDE signs: asymmetry, an irregular or jagged border, more than one colour (dark brown, black, red or grey patches), a diameter greater than 6mm, or clear evolution — new bumps, bleeding, itching, or a scab that keeps returning after healing. Because scalp lesions are hidden under hair, a scalp mole that starts to catch on your comb, or that a hairdresser flags as new, deserves prompt review.
For most people, a scalp mole self-check every 2–3 months is enough — same routine as the rest of your body. If you have a specific scalp mole under active monitoring (a new spot, a mole that's been changing, or a lesion you've been asked to watch), photograph it monthly with your hair parted and a phone flash, and compare each photo against the previous one in ScanSkinAI.
Book a dermatologist within 1–4 weeks if the mole is new in adulthood, growing, changing colour, asymmetric, has irregular borders, is larger than 6 mm, itches, bleeds, or looks different from your other moles (the "ugly duckling" sign). When in doubt, get it checked — early melanoma is highly treatable.
Yes. Take a clear, well-lit close-up photo of the mole every 4–8 weeks using ScanSkinAI's free ABCDE mole tracking. The app saves each scan, scores Asymmetry, Border, Colour and Diameter, and uses AI to flag changes between scans. This is monitoring — not diagnosis. Anything suspicious still needs a dermatologist.
