Hair transplantation generally requires shaving part of the hair or shaving the head hair, which requires a comprehensive decision based on the area of hair loss, hair loss area and personal needs, specifically combined with the following factors for shaving: 1. Area of hair loss: If the area of hair loss is relatively large, it is generally necessary to shave the head hair, because the hair in the back of the occipital area needs to be removed using specific tools before hair transplantation, shaving the head hair is convenient for extracting hair follicles, and can keep the head clean and fresh. It is good for post-operative recovery. If the area of hair loss is small, only for beautifying hair surgery, such as adjusting the hairline, beauty tip, the surgical implantation area is small, the amount of hair transplantation is small, only partial shaving is needed; 2, hair loss area: if it is seborrheic alopecia, the earliest hair loss on the top of the head, it is recommended that patients shave their hair and then have hair transplantation, because the scalp just planted and removed hair follicles, there is epidermal damage, more bacteria and dust in the hair that can easily invade the scalp and cause complications. If there is only hair loss at the hairline that needs to be beautified, shaving the local hair can be done; 3, personal needs: it is difficult for women in general to accept shaving their hair before hair transplantation, if the local situation is okay and there is a need to keep the hair, you can choose to shave the hair transplantation area, and the hair next to the hair transplantation area can be tied up, but you must strictly do a good job of hair hygiene protection to ensure the smooth operation.
