As summer arrives and temperatures soar, people across the UK reach for sunscreen. Yet even the most conscientious sun-worshipper likely neglects one crucial area: the scalp. The skin on the scalp is just as susceptible to sunburn as any other body part, increasing skin cancer risk as UV rays damage skin cells. Moreover, while people vigilantly check moles elsewhere, they often overlook the scalp for early skin cancer warning signs.
Expert Warning on Overlooked Sunscreen Spot
Dr Conal Perrett, Consultant Dermatologist at The Devonshire Clinic, explained: "The scalp is one of the most overlooked areas for sun protection, yet it's particularly vulnerable, especially for individuals with thinning hair, wider partings or bald patches. Many people assume their hair provides complete protection from UV radiation, but that's simply not the case. Even people with thick hair can experience sunburn along their parting, around the crown or near the hairline."
Skin cancers, including melanoma, can develop on the scalp. Because the area is covered by hair, suspicious lesions may go unnoticed longer than on visible areas like the face, neck or arms. Dr Perrett added: "People tend to check moles and skin changes on exposed areas, but very few routinely examine their scalp. That can potentially delay diagnosis."
Symptoms of Sunburnt Scalp
- Flaking
- Tenderness when brushing or washing hair
- Itching
- Redness on the hairline
- Irritation on the scalp
- Warmth on the scalp
- Blistering, swelling and headaches in severe cases
The key distinction between dandruff and scalp sunburn is that dandruff is persistent and develops gradually, while sunburn occurs temporarily after UV exposure. Dr Perrett stated: "Scalp sunburn is often dismissed as a minor inconvenience, but severe burns can require medical assessment. If symptoms are worsening rather than improving, seek professional advice."
Not Just for Thinning Hair
The dermatologist stressed that it is not only those with thinning or no hair who are susceptible. UV damage can occur even in mild temperatures or overcast skies. He added: "The sun can also damage the hair itself. Prolonged UV exposure can weaken the hair shaft, leading to dryness, brittleness and increased breakage. Protecting your scalp helps protect your hair as well."
If your scalp becomes sunburnt, certain shampoos or hair care products may worsen the condition. While recovering, switch to fragrance-free and sulphate-free products. Fragrance-free after-sun products or aloe vera gels can ease discomfort. Avoid scratching, picking or peeling the skin, and refrain from using heat styling tools. When going back into the sun, shield your recovering scalp with a hat or limit prolonged exposure until fully healed. If sunburn persists beyond a few days, or if you notice blistering, considerable swelling, intense pain, fever, chills, dizziness, nausea or signs of infection, seek medical attention.
