Sun Exposure After a Hair Transplant
Written by the Fix My Hair Editorial Team · Clinician-reviewed by Dr Hisham Band · GMC No. 7550130 · Last reviewed 20 Mar 2026Direct sunlight on a healing scalp does three things — none of them good.
Why it matters
Fresh grafts and healing skin are highly UV-sensitive. Sun can burn the area, worsen redness, and affect pigmentation while it’s still settling.
The timeline
No direct sun for 4 weeks. A loose hat is fine after day 10, and SPF50 from week 4 once the skin has closed over.
Long-term care
The scalp stays UV-sensitive for up to 12 months — worth planning your procedure around any sun holidays.
Why the sun is a risk early on
Freshly transplanted skin is healing, thin and more vulnerable than normal scalp. Strong UV can burn it easily, cause inflammation that interferes with graft survival, and worsen redness or pigmentation in the recipient area — effects that can linger. For the first few weeks the grafts simply lack the protection of normal skin and hair, so direct sun is best avoided.
The timeline
For roughly the first two weeks, keep the scalp out of direct sun altogether. From weeks two to four, brief exposure is lower-risk but still worth limiting, ideally with a loose hat once your clinic confirms it won’t rub the grafts. After the first month the grafts are secure, though the healing skin can stay sun-sensitive for several months, so ongoing care still pays off.
Hats, shade and sunscreen
In the first couple of weeks, shade and timing (avoiding midday sun) are safer than putting anything on the grafts — and a hat should only go on once it won’t press or rub. Once healed, a wide-brimmed hat or a scalp-appropriate SPF 30+ sunscreen is the simplest protection. Don’t apply sunscreen directly to grafts in the early healing window; wait until your clinic says the skin has closed.
Holidays and travel
If you have a sunny holiday booked, factor it into your timing — a transplant a week before two weeks in strong sun isn’t ideal. Many people plan surgery for a period without intense sun, or commit to hats and shade if travel is unavoidable.
Long-term scalp care
Beyond healing, sun protection is good lifelong scalp habit — UV ages skin and a sunburnt scalp is uncomfortable under any amount of hair. Once past the healing phase, normal sensible sun protection is all that’s needed.
Common questions
How long before I can sunbathe? Avoid deliberate sun on the scalp for at least the first month, and protect healing skin for several months after.
Can I wear a hat to block the sun early on? Only once it won’t rub the grafts — usually after the first week or two; check with your clinic.
