You can remove your dressing and rinse your head gently after three days of your surgery. First, refrain from standing under the shower jet. Instead of this, you can use a cloth piece and little shampoo to apply over the treated area. Next, with the help of a soft towel, dry your hair gently. But while doing so, make sure not to rub your hairs.
During the first week, also avoid any heavy exercises and physical exertion to let your body heal. It reduces the risk of bleeding.
During the restoration procedure, there are chances that you may develop some of the scabs or go through minor inflammation in the treated area. But no worries, as scabs will vanish within 7 days only.
