A long day under the Sardinian sun can leave your scalp red, tender and surprisingly painful—especially if your hair is thin or you have a parting or a bald spot. You may hear a local “hack” involving cold Ichnusa beer, but beer is not a proven treatment for sunburn. Alcohol and other ingredients may irritate sensitive skin, and pouring beer over a burn does not treat the skin damage.

The safer approach is to cool the area gently, protect it from further sun exposure and watch for signs of a more serious burn.

1. Cool the scalp with clean, cool water

Hold a clean cloth dampened with cool water against the affected area for 10–15 minutes, repeating as needed. A cool shower can also help. Avoid ice directly on the skin, which can cause further injury, and do not scrub or vigorously massage the scalp.

2. Use a gentle moisturizer

After cooling, apply a light, fragrance-free moisturizer or soothing aloe vera gel if it does not sting. Avoid products containing alcohol, strong fragrance or other ingredients that irritate your skin. If your scalp is blistered, do not burst the blisters or apply products without advice from a pharmacist or clinician.

3. Drink water and stay out of the sun

Move into shade or indoors, drink water regularly and keep the scalp covered with a loose, soft hat when you need to go outside. Avoid further direct sun until the skin has healed. If you must be outdoors later, use a broad-spectrum sunscreen suitable for the scalp on intact skin, and reapply it as directed.

4. Should you use cold Ichnusa beer?

No—there is no good evidence that beer treats sunburn. Its cool temperature might feel refreshing briefly, but cool water provides the same cooling effect without leaving beer residue on irritated skin. Beer can also sting or irritate a damaged scalp, and it should never replace established sunburn care.

If you have already tried it, gently rinse the scalp with cool, clean water and stop if the skin stings or becomes more irritated.

5. Be gentle while washing your hair

Use cool or lukewarm water and a mild shampoo only if needed. Avoid hot water, harsh exfoliating products, hair dyes and fragranced treatments until the scalp settles. Pat dry rather than rubbing with a towel.

When should you seek medical advice?

Ask a pharmacist or healthcare professional for advice if the burn is severe, very painful, widespread, blistering or not improving. Seek urgent medical help if you develop fever, chills, dizziness, confusion, repeated vomiting, severe headache or signs of dehydration. These symptoms can indicate a more serious sunburn or heat-related illness.

How to prevent a burned scalp on your next Sardinian beach day

  • Wear a wide-brimmed hat or cap that covers the parting and scalp.
  • Use broad-spectrum sunscreen on exposed scalp areas, following the label and reapplying as directed.
  • Seek shade during the strongest sun and take regular cooling breaks.
  • Remember that swimming and sweating can reduce sunscreen protection.
  • Keep water with you and avoid staying in direct sun when you begin to feel overheated.

The takeaway

If your scalp gets sunburned in Sardinia, leave the beer in the fridge. Cool water, gentle skin care, hydration, shade and protection from further sun are safer choices. If symptoms are severe or worrying, get medical advice rather than relying on a folk remedy.
