When can I shampoo hair after eyelid surgery?

Short Answer: 48 hours after surgeryLong Answer: Shampoo isn't necessarily bad for your surgery. The concern is about getting your incisions contaminated by the water. After 48 hours the first stages of healing have created a water tight bond over the cuts in your skin. You can't scrub or soak, but it's safe to get your incisions wet at 48 hours.If the surgery was not near the hair (eyes/nose/lower face), you can go to a salon and instruct the stylist be very careful about keeping your face dry. I've had a couple patients try to do it at home with little success. Plus going to the salon is nice way to pamper yourself. Please check with your surgeon. They may have specific instructions for your surgery. 

Definitely ask your surgeon, but in my practice, my patients are instructed to wash their hair starting the day after the procedure.  Best of luck!
