Can I Wear Tight Caps 1 Month After Hair Transplant?

The most important is your cap is not to thight and reduce your blood circulation, your grafts needs to have oxygen. Baseball cap can be suitable for that, because they're not touching your grafts and not reducing your blood circulation .

As long as the tight area of the cap doesn't push against the grafts it's probably ok, but remember these new grafts need plenty of blood flow to grow.  You don't want the cap too tight to restrict blood flow.
