Most of the surgical hats are made up of fabric, and hence can be washed and reused. However, there are some disposable surgical hats available in the market for those functioning in extremely contagious or hazardous areas where it might not be ideal (or desirable) to reuse a surgical hat. Disposable surgical caps are an ideal fit if you work in highly infectious environments. http://www.zojemedicalproduct.com/disposable-surgical-clothing-for-medical-use/
