Hair transplantation is the surgical placement of human hairs into a bald or thinning area of the scalp to restore natural hair growth. It is the only proven way to treat permanent hair loss and offers patients an alternative to drugs or other invasive treatments for balding or thinning hair. The success of a hair transplant depends on the number and quality of the hairs harvested from the donor area and how effectively they are placed into the recipient areas. Several surgical sessions are often required for satisfactory coverage. There are many different types of surgical hair transplantation procedures, including slit and strip grafts, punch grafts, mini-grafts and micro-grafts. The size of the follicular units and the method used to create them are important factors in determining what amount of coverage can be achieved with each surgery.서면탈모모발이식
Before a hair transplantation procedure, it is important to understand what the surgeon will do to your skin and scalp and how long the recovery process will take. Your surgeon will explain the various risks and benefits of the procedure to help you decide if it is right for you.
Your doctor will also give you detailed instructions about what you should do at home to prepare for the procedure. You should follow these instructions closely. For example, you will need to avoid taking any medications that may interfere with the outcome of the operation and should stop using any hair growth products.
During the surgery, your physician will use local anesthesia to numb the hair-bearing area of your scalp. After the area has been numbed, your medical practitioner will lift up a section of hair-bearing scalp. Balloon-like devices, called tissue expanders, are then inserted under the skin in this area. These are gradually filled with saline over a period of weeks. This encourages the scalp to grow more skin cells. Once enough extra skin is grown, the medical practitioner will remove the expansion device and cut away the bald or thinning portion of the scalp. The remaining hair-bearing skin will be stitched into place.
The surgeon will then examine the scalp and follicular unit hair grafts under a microscope to ensure they are healthy and suitable for transplantation. The follicular units are then transplanted into tiny “recipient sites” in the bald or thinning areas of your scalp. The follicular units will then be covered with a non-dissolvable, transparent bandage.
Once the follicular unit grafts have been implanted, the medical practitioner will apply an ointment and a pressure bandage to protect them from friction and infection. Your surgeon will tell you how to care for your scalp and grafts after the procedure, so be sure to follow all directions carefully.
After a hair transplant, you will usually see some new growth within a few months. However, it can take up to a year for the full results of the surgery to be apparent. It is important to remember that your “new” hair will fall out and regrow again on a regular basis.부산탈모병원
