Hair transplant is a procedure that requires prior preparation and diagnosis to know the chances of the patient accepting the treatment properly.
That is why before undergoing this surgery, the person is recommended to wash their head with a special shampoo one day before surgery, in order to thoroughly disinfect the hair and scalp.
In addition, the patient must comply with a fast of at least six hours before the intervention.
It is not necessary to take any medication at home before surgery. Only the medications that are being taken at the time of the procedure should be communicated to the doctor.
As part of hair transplantation, it is necessary to stop medications that hinder blood clotting, such as aspirin or ibuprofen.
The patient must take into account that the intervention can last between five or six hours, everything will depend on the degree of alopecia suffered by the person.
Despite its long duration, it is a “simple” technique, which takes time is the processing of follicular units.
Hair transplantation is an outpatient intervention, so it does not require extended admission to a clinic. However, it is recommended to take a companion, since anesthesia is placed in the area to work.
Hair Extraction Procedures
The hair transplant consists of extracting the hair from an area that does not suffer from alopecia, to extract hair follicles and place them in the receiving area.
Usually, the implants are obtained from the neck, so the patient will be placed face down while the follicular units are removed.
To do the extraction, the area to be worked must be shaved, since in this way the healthy hair follicles that will be placed in the area with alopecia can be extracted more easily.
At the time of anesthesia, the patient will only feel the handling in the area.
It is here when three techniques are used to extract hair follicles, which are the FUE, the FUSS and DHI.
The Technique of the strip or FUSS (Follicular Unit Strip Surgery), is when a strip of skin is removed from the scalp with everything and hair.
Then, this is placed under a microscope to remove the grafts. With this technique it is possible to achieve a large number of hair follicles at once.
The scar left by this technique is not visible, unless the patient should shave his head in the future.
FUE technique (Follicular Unit Extraction), is when the follicles are removed by using a very precise special instrument.
This technique is more laborious, but does not leave any scar, also obtaining the greatest amount of grafts.
After the follicles are extracted and divided, they will be implanted in the areas with alopecia.
The specialists place the follicles with more hair in the areas where greater capillary density is desired.
Those who have one or two hairs will be placed in the front hairline.
To implant the hair follicles, a tumescent anesthesia is used, which consists of injecting a wide volume of fluid under the scalp, which allows to make millimeter or microchannel incisions where the grafts will be implanted.
The follicles are placed one by one, so the work is hard, but ensure a greater amount of implants.
There are other methods used in hair transplant operations such as the DHI (Direct Hair Implantation) technique. This is one of the most advanced on the market, and makes the resulting appearance more natural and safe thanks to the fact that it is done manually. This gives the specialist in charge of the procedure a better control of the angle and depth of the implant.
