Generally speaking, the hair block area is smaller than the headgear, and it is relatively cheaper. It has good air permeability and is convenient to wear. The headgear has a large area. It is time-consuming and labor-consuming to process. The processing and price of the wigs is better than the hair block. The headgear is more realistic after wearing, the overall effect is good, and the connection with real hair is good, so the hair block and the headgear have their own advantages.
