What is a hair transplant? Human hair can be transplanted just like any other tissue in the human body. Hair transplantation is the process of removing the hair follicles from the scalp by using a special instrument to remove the tissue around the hair follicles and transplanting it to a location where the hair is needed and has been prepared to receive it. Hair loss is caused by burns, infections, various types of trauma and alopecia areata (mostly in male patients), and leprosy can also cause hair loss. The donor area for hair transplants is usually the scalp. For eyebrow or eyelash loss that is not too extensive, the healthy side of the eyebrow or nose hair can also be taken to repair it. What are the conditions for which hair transplantation is indicated? Hair transplantation can be performed for all types of baldness, loss of eyebrows, eyelashes (especially eyelashes on the upper eyelid), or beard loss. In what cases can’t I have a hair transplant? Eyebrow hair loss can be repaired with hair strip free grafts in women and with superficial temporal vascularized island scalp flaps in men. Hair transplantation is not recommended when there is infection present in the recipient area or when there is insufficient local blood supply. What are the side effects of hair transplantation? Wound area is prone to infection, hair follicles left in bundles can cause folliculitis after surgery. Hair transplantation procedure: The methods of transplantation include strip transplantation, small block transplantation, punched hole transplantation, and various kinds of local flaps, subcutaneous tibial flaps, island flaps, free flaps, and vascular implantation of prefabricated island flaps (secondary vascularized flaps) in hair-bearing areas, and so on. As long as there is no damage to the hair follicles during cutting and transplantation, no damage to the blood supply of the tips of the various types of flaps, good conditions of blood supply in the donor area and the mastery of proper plastic surgical operation, the transplantation will generally be successful. Hair drilling transplantation is performed by transplanting small pieces of skin with hair. It is suitable for male pattern baldness, scarring baldness, scarring baldness on the scalp after thermal and chemical burns, radiological injuries and skin head lacerations. In the case of male pattern baldness, a hair line that has been mutually agreed upon with the patient is first drawn. Then the location of the drill hole to receive the graft is selected. The layout to which the grafts are transplanted should achieve the best results cosmetically, and should also take into account possible hair loss with age. For the band hair scalp site are generally selected hairy back hair or ear on the back side, because these areas are the least bald. 24 hours before the operation, within the hot water soap to wash the hair fully 2 times, remove the scalp on the oil, dander and dust. The hair at the donor site was first cut off against the scalp, leaving a stubble of about 0.2 mm in length in order to be able to recognize the direction of hair growth for easy anvil extraction and subsequent reference during transplantation. After routine local disinfection, local anesthesia was administered with 1%-2% procaine or 0.25%-0.5% lidocaine with an appropriate amount of epinephrine. A 3-mm diameter drill was used to cut the skin pieces. Care should be taken during the operation so that the drill is drilled into the scalp at an angle parallel to the direction of hair growth, so as not to cut and damage the hair follicle and bulb. When drilling the skin piece of the hair supply area, it is necessary to leave sufficient spacing between the drill and the drill hole to prevent ischemic necrosis of the hair left behind. Once taken, the drilled area is stopped from bleeding and then bandaged with a sterile dressing. What equipment is used for hair transplantation? Commonly used surgical equipment and devices. What preparations are made before hair transplantation? 1, should choose good hair quality and no skin disease of the donor area. The surgeon should have a deep understanding of the direction of hair growth in different parts of the body, the approximate angle between the hair and the scalp, and then supplemented with special instruments, skillful techniques to cut the hair, so as not to damage the hair follicles. 2, accept the preparation of the hair transplantation area, including cleaning, hot compresses and vasodilator drugs to improve local blood circulation, scar excision thoroughly or hair transplantation cavity size, depth appropriate to the transplantation of hair strains, bundles, strips and the recipient area of the tissue tightly combined and pay attention to the prevention and treatment of infection is conducive to transplantation of hair survival. How to take care of hair transplant after surgery? After the operation is to protect the hair, change the medicine and so on. What are the after-effects of hair transplantation? Hair transplantation is a permanent hair transplantation, it is the own hair surviving in the autologous skin, it will not fall off, and the nature and growth pattern of the hair in the original donor site are completely consistent, and the density of hair can be close to the normal density, and the effect is real and natural.
