A mole hidden beneath your hair can be easy to miss for years. Knowing how to check scalp moles gives you a practical way to notice a new or changing spot, but it does not replace a professional skin examination. The scalp is one of the body areas most people cannot inspect properly alone, and delayed assessment can mean a concerning lesion is found later than it should be.

If you notice a spot that is new, changing, bleeding or simply does not look right, arrange a skin check promptly. Every minute counts when melanoma is a possibility.

Why scalp moles deserve attention

Moles are common and most are harmless. They may be flat or raised, tan, brown, black, pink or skin-coloured. The difficulty with scalp moles is not that every spot is dangerous. It is that hair can conceal changes that would be obvious on an arm, leg or face.

Australia has some of the world’s highest rates of skin cancer, and cumulative UV exposure can affect the scalp, particularly along hair parts, thinning areas and bald patches. People with fair skin, a history of sunburn, many moles, a personal or family history of melanoma, or significant outdoor work or recreation may have a higher risk. Skin cancer can also occur in people with darker skin tones, so no one should assume they are exempt from checking.

A scalp lesion may be noticed as a mark, lump, scab, itchy patch or sore area rather than a classic dark mole. Not all melanomas are brown or black. Some can be pink, red, pale or skin-coloured.

How to check scalp moles at home

A home check is most useful when it becomes a regular habit. Aim to examine your skin roughly once a month, ideally in good natural light. You will need a hand-held mirror, a larger wall mirror, a comb or hairdryer, and your mobile phone or camera. A trusted partner, family member or friend can make the process much more reliable.

Start with dry hair. Stand or sit where you have strong light and use the comb to create a part from your forehead to the back of your head. Check the exposed strip of skin using the hand-held mirror and the larger mirror. Move the part a few centimetres at a time until you have worked across the top, sides and back of your scalp.

Do not forget the areas around the hairline, behind the ears, the nape of the neck and any thinning or balding areas. These places receive sun exposure but are commonly missed. If your hair is dense, using a hairdryer on a cool setting can help separate sections while someone else looks.

Take clear photos of any mole or mark you want to monitor. Include one image showing its location and another closer image, with a ruler or measuring tape beside it if possible. Photos cannot diagnose skin cancer, but they can help you and your clinician identify genuine change over time. Keep the images private and dated.

If you have a trusted helper, ask them to inspect the scalp in small sections. They should be looking for a spot that appears different from the others, not trying to make a diagnosis. A hairdresser may occasionally notice a lesion, but they are not trained to assess skin cancer. Treat their observation as a reason to check the area and book a clinician if there is any concern.

What to look for: the ABCDE signs

The ABCDE guide is a helpful starting point for pigmented moles. Look for asymmetry, where one half differs from the other; an irregular or poorly defined border; uneven colour, such as different shades of brown, black, blue, red or white; a diameter that is growing, especially beyond about 6 mm; and evolving, meaning any change in size, shape, colour, surface or sensation.

On the scalp, evolution is often the most useful clue. A mole that has been stable for years is generally less concerning than one that is noticeably changing. However, a stable-looking mole can still need assessment if it has an unusual appearance or you cannot remember when it first appeared.

Also use the “ugly duckling” principle. Most of your harmless moles tend to share a pattern. A lesion that looks distinctly darker, larger, more raised or otherwise unlike your other spots deserves a closer look.

Warning signs that should not wait

Book a skin check as soon as possible if you find a new mole in adulthood, a changing mole, or a lesion that looks unlike your other marks. Do not wait for a routine self-check if a spot is bleeding, crusting, ulcerated, painful, persistently itchy or failing to heal.

Seek timely medical advice for a new raised lump, a dark streak or patch that is enlarging, or a pink or red scaly area that remains after several weeks. A spot may be irritated by brushing, colouring products or scratching, but repeated irritation should not be assumed to be the explanation without examination.

A mole can also change during pregnancy, with age or after injury. Those changes may be benign, but they still need a clinician’s assessment if they are new, persistent or difficult to explain. It is safer to have an uncertain spot checked than to watch it for months.

When a professional skin check is the right next step

A GP, dermatologist or skin cancer clinician can inspect a suspicious area with a dermatoscope, a specialised magnifying instrument that reveals patterns not visible to the naked eye. If necessary, they may photograph the lesion for monitoring, perform a biopsy, or arrange removal. These decisions depend on the lesion’s appearance, your risk factors and whether it has changed.

You should consider regular professional skin checks if you have had melanoma or other skin cancers before, have many atypical moles, have a strong family history of melanoma, take medicines that suppress the immune system, or spend substantial time outdoors. The right interval varies from person to person. Ask your clinician what schedule suits your risk.

Do not attempt to remove, freeze, burn or cut off a scalp mole yourself. Home treatments can cause infection and scarring, and they can make an accurate diagnosis harder if cancer is present. A lesion should be assessed before it is treated.

Make scalp checks easier to keep up

Choose a repeatable time, such as the first weekend of each month or after a haircut. If you colour your hair, use the time before applying dye to inspect the scalp carefully, as colour products can temporarily stain the skin and make assessment harder.

Sun protection also matters. Wear a broad-brimmed hat when outdoors, particularly during prolonged work, sport, gardening, fishing or beach time. Apply sunscreen to exposed scalp areas, hair parts and thinning patches, and reapply it as directed. A hat and sunscreen reduce UV exposure, but they do not remove the need to check your skin.

Your scalp is difficult to see, not impossible to protect. A few careful minutes, a set of dated photos and prompt clinical assessment when something changes can turn uncertainty into action. If a spot worries you, trust that instinct and book a skin check.
