The loss of hair is generally a hormonal disorder which can affect men and women. A number of valid treatments exist for each type of hair loss, which is diagnosed by a conscientious hair analysis or tricogram, so that the most suitable treatment for each case can be carried out.
Nowadays we know that half the worlds’ population is or will be bald in the near future. On the other hand the number of surgeries for the treatment of baldness has grown in a geometric proportion because of the natural and good results of new techniques. Now the technique of micrografting allows for very satisfactory results for patients and doctors. The patients’ profile with best results is that of between 30 and 50 years old, with a doner area of great density and with baldness type 1 to 5 in accordance to the Norwood or Ludwig classifications.
Baldness is a progressive alteration that causes the gradual loss of hair in men and women at the front, top and back areas of the head. Because of heredity, the hormone testosterone interacts negatively with the hair follicles determinating the gradual loss of hair. The hair of the sides and lower back of the head is not affected allowing for a transplant. The pattern of femenine baldness is similar to that of men, showing itself to be more diffuse and with a clear hormonal dependency.
Techniques of Capillary Micrografting.
Right now we use two techniques of capillary transplant:
F. U. S. Technique or Strip Technique:It consists in extracting a section of scalp with its hair follicles from the back area of the head, with the result of a wound that will be sutured with stitches, it will heal afterwards with almost no sign. This kind of technique is adequate for patients that suffer from type 6-7 alopecia according to the Norwood-Hamilton classification, this is the most “classic” technique that has been used up til now. Its main inconvenience is the scarring, that in the majority of cases is insignificant, it can be seen when the patient has very short of shorn hair. The technique is performed in 3-4 hours under local anaesthetic and sedation. The patient returns home the same day and should have 3-4 days rest before returning to work.
F.U.E. Technique (Folicular Unit Extraction) :It appears in the year 2001, when Drs. Woods in Australia started to extract hair with small biopsy punches of 1mm of diametre, then inserting them in areas with no hair, without the necessary of removing a strip of skin, with its resulting scar, from the back area of the head. The follicular units or “grafts” are extracted one by one with very precise material, that allows the transplant to hairless areas with absolute precisión and without discomfort for the patient. The follicular units can contain 1, 2, 3, 4 or 5 hairs, and will be implanted according to the areas that need filling, using fine follicular units in the more visible areas and using follicular units of more hairs for those areas that need more density. All of this methodology makes our capillary implants to be absolutely natural following the newest fashions.
Nowadays, in capillary micrografting sessions about 250 to 2,000 follicular units are implanted, depending on the needs of the patient and the density of the hair contained in the done rarea, with the possibility of performing from one to various sessions in patients that desire a total hair repoblation. The main secret of the F. U. E. technique is based on the ability and expertise of the team of doctors and assistants to extract the largers number of follicular units in the least possible time.
The F. U. E. technique also allows to inject hair in areas with alopecia with grafts from areas like tórax, beard, genital area or back. Grafts in eyebrow and genital area can also be performed with marvellous results.
Methodology of the F. U. S. and F. U. E. techniques .
With both techniques, small grafts containing variable numbers of hair follicles are taken from the doner areas of the side and back areas of the head and placed in the areas with baldness.
The tecnique consists in using micrografts to obtain a natural and soft hairline, one, two or three grafts are used for the areas just behind the line before and minigrafts to complete the density of the top part of the head and crown.
The main objective of surgery is to obtain a natural appearance so the kind of baldness of the patient, the availability of hair in the done rareas, the density, the growing direct and the number of necessary sessions to get the best possible result must be analyzed.
HAIR DENSITY: The density of hair in the doner areas varies greatly person to person. The density of hair is determined by the distance between the follicles, not by the texture or calliber of the hair. It is common for a patient with fine hair, to have excellent density and produce a great number of grafts.
It is important in the physical exam to determine which is the best area to dónate hair permanently.
GRAFT SIZES: :To obtain a natural appearance we need to use small grafts placing them with systematic irregularity, very near to each other:
Monografts: contains 1 to 3 hairs.
Mono/Duo/Trio (MDT): Contains 2 to 4 hairs.
Mini-grafts: Contains 3 to 5 hairs. Generally mini-grafts are used to improve the density on all the scalp on persons with low density. .
The main advantages of the capillary micrograft are::
Hair by hair..
With the patients own hair.
In just 3-4 hours with the F. U. S. technique and 4 to 7 hours with the F. U. E. technique
Respects the natural inclination of the hair.
No possibility of rejection.
The hair continues to grow for the rest of the patients life.
No scarring with the F. U. E. technique.
Natural and permanent results.
Only scientifically tested technique.
Most used technique in the United States
