Sun exposure and the recipient area

Why is healing scalp skin more vulnerable to sun than intact skin?

The recipient area is thousands of small healing wounds with increased blood supply and a compromised barrier, giving it less protection than intact skin on the most sun-exposed part of the body. Burning it can prolong inflammation, deepen and extend redness, and trigger post-inflammatory pigment change that takes months to fade.

What is the practical timeline for sun protection after a hair transplant?

In the first two weeks avoid direct sun entirely, with no sunscreen on the recipient area unless the clinic approves; weeks two to four call for shade and a loose hat; from around a month, once healed, sunscreen can be applied; months one to six still need continued care against pigment change.

• First 2 weeks: avoid direct sun. No sunscreen on the recipient area unless your clinic specifically approves it.
• Weeks 2 to 4: shade, a loose hat once permitted, and avoiding midday sun.
• From around a month, and only once healed: sunscreen on the scalp where hair does not yet cover it.
• Months 1 to 6: continued care, because the area is still prone to pigment change.

Who faces the highest risk from sun exposure after a hair transplant?

Darker skin tones are more prone to post-inflammatory hyperpigmentation, while fair skin burns faster and shows redness more clearly. Shaved procedures leave the scalp fully exposed for longer, and anyone travelling home to a sunny climate faces peak UV exposure exactly when the recipient area is at its most vulnerable.

What should you do if the recipient area gets sunburned?

Get out of the sun immediately, cool the area gently without pressing on grafts, and keep it moist following your clinic's routine, reporting any blistering to them. Avoid after-sun products containing alcohol or fragrance, since a healing recipient area cannot tolerate those ingredients.

Sun protection belongs with the other long-running habits described in the aftercare guide.
