Is your scalp burning in the sun? Why it happens and how to stop it

As temperatures soar during summer, sunburn becomes a common concern. However, one often-overlooked area is the scalp, which can also suffer serious damage from prolonged UV exposure.

What is a sunburnt scalp?
A sunburnt scalp—medically known as solar dermatitis—refers to sunburn occurring on the top of the head. According to a cosmetic plastic and hair transplant surgeon and Medical Director at DHI India, this condition can affect anyone, regardless of skin tone or hair type. It is just as painful and potentially harmful as sunburn elsewhere on the body.

Symptoms to watch for:

• Redness and tenderness on the scalp

• A sensation of warmth or burning

• Dry, flaky, or peeling skin (typically within 7–10 days)

• Blisters, swelling, and in some cases, nausea (in severe sunburn)

What causes it?
Prolonged sun exposure without protection is the primary cause. Those with thinning hair or baldness are especially vulnerable. Other risk factors include:

• Living in high UV-index areas

• Fair skin or a family history of skin cancer

• Exposure near reflective surfaces like water, sand, or snow

  Potential consequences:

  • Premature ageing of the scalp skin

  • Heightened risk of skin cancer, including melanoma

  • Hair thinning or loss due to damage to hair follicles

  How to prevent a sunburnt scalp:

  • Wear a wide-brimmed hat or UV-protective headwear

  • Apply broad-spectrum scalp sunscreen with SPF 30 or higher

  • Limit outdoor exposure during peak UV hours (10 a.m. to 4 p.m.)

  • Avoid tanning beds and artificial UV sources

  • Seek shade whenever possible

    What to do if your scalp is already sunburnt:

    • Avoid further sun exposure

    • Stay well hydrated

    • Apply soothing products like aloe vera or calamine lotion
    • Take cool showers to ease discomfort

    While often overlooked, scalp sunburn can have lasting effects. Using proper sun protection and being vigilant about scalp health can go a long way in preventing serious damage.
