This is not absolute. When transplanting hair, the hair transplant doctor should make a judgment according to the location of your hair loss and the distribution of resources in the hair removal location, and choose the most suitable hairstyle for you. With the development of hair transplant technology, shaving your head is not the only way. At present, hair transplant hospitals generally make perfect hairstyles without affecting their image. However, it is recommended that most men shave their heads when transplanting their hair. Without the hindrance of other hair, the effect of transplantation will be more ideal. Even if they don't want to shave their heads, the hair on the donor site must be cut off, which means that where we extract hair follicles, we must cut that part of the hair short, usually leaving about 0.5cm of hair. We can't pull out too long hair, and it's not convenient to grow too short hair.
