A dermatologist has issued a warning about the risk of skin cancer developing on the scalp, an area often overlooked when it comes to sun protection. While people tend to shield their face, shoulders, and arms from harmful UV rays, the scalp remains highly vulnerable and frequently neglected.
Dr. Conal Perrett, Consultant Dermatologist at The Devonshire Clinic, explains that many individuals don’t realize they’ve sunburned their scalp. One common sign—flaking and peeling skin appearing days after sun exposure—is often mistaken for dandruff or dry scalp.
“People often don’t recognize their scalp has been burned until it begins to peel,” says Dr. Perrett. “At this point, many assume it’s dandruff, but it’s actually the skin shedding due to UV damage. If you notice flaking, tenderness, or irritation after spending time outdoors, sunburn should be considered.”

Scalp sunburn can be tough to detect since it’s concealed beneath the hair. Symptoms may include tenderness when brushing or washing hair, itching, redness along the hairline, warmth, and flaking skin. More severe reactions might involve blistering, swelling, and headaches.
“The scalp is one of the most neglected areas for sun protection, yet it’s particularly vulnerable,” Dr. Perrett emphasizes. “Those with thinning hair, wide partings, or bald patches are at higher risk, but even people with thick hair can burn along their parting, crown, or hairline.”
Repeated UV exposure contributes not only to immediate discomfort but also to premature skin aging and an increased risk of skin cancer. Skin cancers on the scalp can be harder to spot compared to more visible areas like the face or arms. Because people rarely examine their scalp thoroughly, suspicious moles or lesions may go unnoticed, delaying diagnosis.
UV rays can also harm hair health, weakening hair shafts and causing dryness, brittleness, and breakage. Protecting the scalp thus also benefits hair quality.
Common misconceptions persist regarding scalp sun protection. Dr. Perrett notes that scalp sunburn isn’t limited to those who are bald; anyone can be affected. Hair provides some defense but is not a substitute for sunscreen or hats. Furthermore, UV damage can occur even on cooler or cloudy days since it’s caused by ultraviolet radiation, not temperature.
Unlike dandruff, which is a chronic condition, scalp sunburn manifests relatively quickly after UV exposure and is often accompanied by redness, tenderness, and sensitivity. Severe sunburns may require medical attention, especially if symptoms worsen instead of improving.
Dr. Perrett concludes, “People often take great care to protect their face and shoulders but forget their scalp. Since the scalp is less visible and harder to check, skin cancer can go unnoticed longer. Taking extra care to shield your scalp can prevent both short-term burns and more serious long-term skin issues.”
