I got sunburn one month after the hair transplant (Photo)

This is what I looked like.  Did I do any damage to the grafts?

The skin of a hair transplant came from the back of your head which has been protected from the sun since you were born. Now you expose the skin to sun so I would expect it to burn. Also ultraviolet light is not good for wound healing.  Use a good sun blocker or a hat and you will be protected. A single sun burn to the grafts probably will not permanently damage them
