Types of hair transplants
Regardless to the conventional and abolished hair transplant procedures, such as punch graft which had disappointing and undesirable consequences, two academic and standard methods are described below. Moreover, some further information are presented about the technique called FIT, which is highly advertised nowadays.
Follicular Unit Extraction method or FUE: This method is similarly implemented applying local anesthesia without general anesthesia, and the patient will be of total consciousness and have little rest if desired. Conversely, this technique requires shaving the back of the scalp. Similar to the previous mentioned procedure, in FUE method the grafts of one, two, three or four hairs are removed without making incision and using surgical instruments. The grafts then will be transplanted on the related places on scalp. Most hair transplant candidates prefer to undergo the FUE method, in which no surgical incision is applied. This may have several reasons as being afraid of the term surgery and incision, which is used in FUT technique. Being worried of the surgical scars and expanding advertisements of unprofessional clinics in favor of FIT are also considered as the probable causes of this fear. However, most patients who have experienced both these methods for any reason prefer the FUT method. Because of its low speed, the FUE technique needs to be done in frequent sessions and may take several hours (even up to 12 hrs). In other words, to achieve a similar hair density in a 6-hours session of FUT, more than 20 hours of FUE is required. In addition, as the method is time consuming and needs the personnel and operating room for a more period of time, the patient should pay more. Nonetheless, this technique is performed in this clinic for those who intend to undergo FUE, particularly those who need hair transplantation on small sites as the burned regions.
FIT method: This method is also a non surgical method, and has similarities to the FUE method, but since extremely sharp and fine punches are used in this technique, the grafts are not removed as multiple hairs and it does not look like natural on the transplanted place. Besides, due to the damaged roots and their stem cells, and also because the hairs may be cut by the mentioned punches, a high percentage of the transplanted hairs would not thrive or may shed irreversibly after a several-years-period of growth due to the damage entered the stem cells.
The condition of natural hair transplant: • Types of transplantable hair losses • The patient should make a right decision based on real information and the patient’s expectations and imaginations should be adapted to the facts. The applicant should have decided to undergo the natural hair transplant surgery with quite awareness. • The appropriate donor site hairs should be examined prior to the operation. The standard operating room should have a desirable sterility condition, light and air conditioning system. According to the health ministry rules it is banned to perform hair transplant surgeries in private clinics. • According to the health ministry rules hair transplant surgeries must be carried out by a skin specialist, or a trained facial, head and neck plastic surgery specialist. • The experienced technicians and personnel and well-equipped instruments are applied.
Hair loss types A. Hereditary and hormonal hair loss (alopecia or androgenetic alopecia): Male alopecia: The onset of this kind of alopecia is commonly occurred as early as sexual puberty due to male sex hormone enhancement, as it may be unrecognizable for the person because of the gradual hair loss and the large amount of hair in its early periods at the beginning of puberty (100 to 150 strands of hair per cm of scalp) and may not be considered up to several years. This kind of alopecia has various patterns and occasionally comes to attention by recession of hairline in the vertex or sometimes appears as a decline in hair of the top of the vortex (frontal region) without the hairline recession. However, in most cases it occurs as an intermediate form. Besides the decline in hair, this type of hair loss represents thinned and fluffy hairs, in which it would be obviously observed even in the cases of complete alopecia. Most of the natural hair transplants referred people are suffering from male hair loss or alopecia.
Female alopecia: The female hereditary- hormonal alopecia occurs as the male form of the disorder in some cases, which is observed as a decline in hairs of the vortex without recession of the hairline. This form of alopecia involves the whole scalp and hair decrease in seen in all regions on head. The intermediate forms are frequently reported. Natural hair transplants are feasible in this kind of alopecia in women as well. Hair loss induced by accidental and burning lesions, and also skin demolition alopecia due to fungal diseases in childhood and some congenital disorders. In most cases of the above-mentioned alopecia it is practical to perform hair transplants. Stress and internal diseases induced hair loss (telogen hair loss) For the high speed development of the hair generator cells, these cells have great metabolic requirements, and any physical (diseases) or mental stress may cause to a change in body metabolism and hair loss as well. If these stresses prolong, a chronic and long-term alopecia will be the outcome.
The followings may be mentioned as the reasons of hair loss: Different kinds of malnutrition including severe weight loss related to nonstandard diets, in which weight loss occurs (more than 2 to 3 kilograms a month) nutritional deficiencies such as iron, zinc and vitamin deficiencies severe bleeding hyperthyroidism and hypothyroidism post parturition and post surgery alopecia nutritional deficiencies induced chronic diarrhea severe febrile illnesses some drug consumptions mental and nervous breakdown severe fears, etc.
Scalp inflammation induced hair loss Any acute or chronic inflammation of scalp can cause to hair shedding, which may be transient or permanent based on the causative inflammatory disease. Inflammations as tropical medicine sensitivities and hair colors, dandruff and severe pruritis of scalp are also included in this type of alopecia. While some of these diseases have high resemblance with ordinary sensitivities and restricted pruritis of scalp, may lead to durable and irreversible hair loss (not reversible even with surgical methods). Therefore, the scalp should be examined precisely in these cases.
Traction alopecia This type of hair loss leads to a permanent alopecia following the hair root damages. Traction of eyebrows while trimming, being picked in fights, traction induced by tight tying up, or using twist hair brushed or hair ironing machines, and also usual traction of hair could be mentioned as the probable causes of this kind of alopecia.
Spot baldness or Alopecia Areata Also called nervous alopecia, this type of hair loss is observed in people with genetic background, but it does not mean that other members of the family are inevitably involved. Hair shedding is mainly occurred as a result of atopic immune system reactions (eutoimmune reactions) in this form of alopecia, and the treatments are managed to suppress these reactions. This disorder is ranged from a restricted hair shedding to total body hair loss, and the treatments vary depending on the development of the disease and also the age at which the patient is involved.
