Avoiding direct sun exposure on the scalp for at least the first two weeks after a hair transplant is generally recommended. The scalp is particularly sensitive and vulnerable during this initial healing phase. After this period, you should still exercise caution. If you need to be in the sun, it’s advisable to wear a hat or use a strong sunscreen (SPF 30 or higher) to protect the transplanted area. Prolonged sun exposure can not only cause damage to the healing skin but also potentially affect the success of the transplant. It’s always best to consult with your hair transplant surgeon for specific guidelines and recommendations tailored to your case.
