Recover Hair Transplant center uses fine punch techniques due to which wound healing is faster. You need not worry about protecting your head from physical factors such as dust, sunlight and sweating. But, for cosmetic purposes you can wear a bandana or a loose cap. If the cap or bandana is tight it will pull your hair, which is not recommended after the hair transplant because it leads to damage of the transplanted follicles(specially the temple area on the head)
You can also opt for a Turban as a turban presses the hair instead of pulling it.
