The Micro Graft of Hair, a Natural Rendering
A few years ago, hair transplants were accused of giving a leek field appearance. This aspect was due to grafts too big, each containing more than 10 hairs. Currently two techniques make it possible to obtain grafts of 1 to 6 hairs, 1 to 2 follicular units (each follicular unit is formed from 1 to 3 hair bulbs)
Micro grafting involves carefully cutting a strip of skin, taken at the occipital level, into follicular units. The treatment provided at Hair transplant cost in Lahore is quite similar as we carefully examines all the methods and the Extraction of follicular units (FUE) allows the follicular units to be taken directly by means of circular lancets 1-2 mm in diameter, called punches.
The micro graft gives a horizontal scar at the nape of the neck, which can sometimes widen while the FUE leaves multiple scars of 1 mm diameter most often invisible even if patients wear very short hair. This technique is our preference.
How Is A Hair Transplant Done?
At the level of the donor area (occipital region), the hair is cut with the clipper (about 5 mm in length) and local anesthesia is performed.
The grafts are harvested by means of punches whose size is chosen according to the zone to be grafted (frontal line: punch 1.25 to 1.5 mm in diameter and more posterior zone: punch of 1.75 to 2 mm of diameter). This first step is the most thorough and requires a trained operator. The grafts are sorted by an assistant, according to the number of bulbs they contain and arranged on compresses soaked with saline.
The grafts without bulbs are eliminated. In a second step, the recipient area is anesthetized and then pierced with small holes or slots, in which the grafts are introduced using micro-tongs, respecting the direction of implantation of the hair to avoid the ears. The number of grafts varies according to the surface to be grafted (one can graft up to 600 grafts in one session, or more than 2000 hairs) but also the capacity of the donor area.
What to Do After the Session?
A dressing is necessary for 3 days in the donor area but not the grafted area, which is only covered by a spray lacquer: A shampoo is allowed from the 5th day. The consequences are not painful; however the patient may present edema in the forehead for a few days, if the grafted area is extended. Crusts are formed after 24 hours and fall 15 days later carrying most grafted hair which will not regrow until the 3rd month (regrowth rates are usually> 90%). Sometimes hypoesthesia (decreased sensitivity) or dysesthesia (tingling) in the neck can occur and persist for several months. There is no transplant rejection because it is the patient’s hair.
What Principle Does A Hair Transplant Work On?
Men are programmed to have hair for a hundred years: each hair has 25 cycles that is to say it will push and fall 25 times, each cycle for about 4 years. But, in case of androgenetic alopecia (baldness), the cycles will be shortened because of a hypersensitivity of hair bulbs to androgenic hormones; the 25 cycles are then more quickly exhausted. This hypersensitivity affects only the hair bulbs of the fronto-temporal zone; baldness always spares the occipital crown. Indeed, the bulbs of the occipital zone having no androgen receptors, they are insensitive to these hormones and remain so even when transplanted to the level of the bald area. This explains why grafted hair does not fall.
Can Scarring Alopecia Benefit From A Hair Transplant?
Postoperative scars (neurosurgery, facelift scars) and post-traumatic scars (road accidents), alopecia secondary to burns or occurring after certain dermatological diseases can be corrected by this technique. When scarring skin looks of poor quality, it is necessary to do a first test session, a few dozen grafts to verify that the grip is correct. In contrast, alopecia areata is not an indication of hair transplantation.
