- Follicular Unit Extraction is the technique of obtaining hair by extracting hair follicles from scalp donor areas and then implanting them into the recipient area (bald area). Follicles are normally extracted one by one and those that meet a specific set of morphological requirements and are considered viable are placed in petri dishes containing 0.9% NaCl solution at temperatures of 4-5 ° C and subsequently implanted. in the receiving area without being damaged.
- FUE Follicular unit extraction
- This technique of hair transplantation allows us to obtain single, double, triple or quadruple follicles, according to the specific needs of each patient, without causing trauma, since no sutures are made or scars result from this process.
- a small incision with a maximum diameter of 1 mm is made when each follicular unit is extracted. Wound healing usually takes 3 to 4 days and resorption of the facial edema is usually complete within 7 days after surgery. The patient returns home the same day.
- This technique is useful for patients with a "good” donor area (with more than 15 follicles per cm 2 ); “reasonable” (with 10 to 15 follicles per cm 2 ) and “bad” (less than 10 follicles per cm 2 ) cm 2 ).
- Each intervention usually takes about 6 hours, and it is possible to interrupt for brief periods and resume the process or perform the treatment at different stages, encompassing more than one intervention. It is advisable to transplant the extracted follicles within a maximum of 9 hours from the time of extraction of the first follicle in order to preserve their integrity.
- the Health Viable® clinic has transplanted by intervention an average of 1,250 follicles, and in some patients transplanted more than 1,500 follicles - one by one - anything like 3,000 hairs, as each of these follicles can contain between 1 and 4 hairs. and rarely 5.
- the transplanted hair is very short and usually falls out in the first three months after the intervention to renew the apical part or stem. The root produces new hair that will grow to its normal texture and thickness. Once transplanted, the follicles will continue to produce hair as they did in the area where they were before being transplanted.
- transplanted hairs are not subsequently influenced by the metabolism of DHT - dihydrotestosterone and are therefore less likely to fall back due to this hormone.
- anesthesia may also be applied progressively throughout the intervention.
- An intermediate procedure can even be adopted, combining simultaneous anesthesia at multiple sites and strengthening of some regions of the head during the surgical intervention.
- the swelling observed after anesthesia application is useful during manual extraction of the follicles as it confers stiffness to the surface of the skin, facilitating the cutoff that isolates the follicle.
- the absence of adequate swelling in the extraction area during manual extraction requires a greater puller pressure to isolate the follicle.
- the applied anesthesia covers the entire intervention region, with multiple simultaneous and / or progressive applications, with the advantage of causing one. minor swelling or swelling, as automated extraction does not require these conditions to ensure effective follicle extraction. At the same time, the postoperative pain experienced by the patient is also considerably reduced.
- the "pop-up" phenomenon is the unwanted complete exit of newly implanted follicles and can be caused by 2 or more factors acting together, namely in the presence of: a) Difficult area of haemostasis - Sometimes happens in young patients healthy without changes in coagulation or signs of liver function;
- Hair transplantation effectively consists of extracting and harvesting hair follicles from the donor area to implant in the recipient area.
- the donor areas are located in the region of the "nape" and lateral faces above the ears, as these areas are not affected by baldness. Hair characteristics in different donor areas are important in determining the number of hairs of a given structure to be extracted for a given recipient area.
- the thicker follicles are located at the "nape" and most usually contain 2, 3, or 4 hairs and rarely 5. These follicles, having a larger structure, are implanted in the "crown" and at the top of the head. Follicles containing only one hair are implanted in the capillary front line ( Figure 9).
- STRIP is the classic and widely used follicular removal technique in which a single, double or triple scalpel is used to remove a strip of skin containing hair in the donor area. Later the follicles are dissected from the skin strip, ready to be implanted. Follicular units can be individualized or grouped. The incisions made for removal of the strip are closed with sutures or staples.
- Elliptical STRIP is a variant of the above, in which the strip incision has an elongated oval shape.
- Graft extraction is a virtually disused technique where large clusters of follicles are removed in round pieces with a 3-5 mm punch and implanted without separation of follicular units.
- the hair should be assessed at the level of its biochemical structure, which defines the phase of the cycle. They are elected as suitable for transplantation hair whose structures are in the anagenic or growth phase.
- the terminal hairs are thick (up to 0.6 mm).
- the matrix cells stop dividing and growth is arrested. They enter the catagen phase for 2-3. weeks and the matrix cells are fully keratinized.
- the hair follicle germ cells cluster in the basal layer of the protrusion of the outer root sheath. It is from these cells that the matrix cells are formed. Matrix cell growth and differentiation are under the influence of substances produced by dermal papilla cells. On the other hand, the secretory activity of the dermal papilla is controlled either by substances produced in the cells of the spinous layer of the outer root sheath or by hormones.
- the spinous layer cells produce peptides of 3000 daltons or more, which increase the number of papillary cell mitoses by two to five times. It has recently been found that basic fibroblast growth factor (bFCF) and platelet-derived growth factor (PDGF) enhance dermal papilla cell growth.
- bFCF basic fibroblast growth factor
- PDGF platelet-derived growth factor
- stromelysin an enzyme, matrix metalloproteinase
- TGF- ⁇ growth transforming factor beta
- dermal papilla cells produce numerous cytokines that influence the proliferation of hair matrix cells. Some of these act by stimulating this proliferation, others by inhibiting it.
- Interleukin 1 (IL-1) inhibits hair and follicle growth, but only after 2 - 4 days of latency. Increasing the concentration of IL-let in extracellular fluid during inflammation could be one of the reasons why alopecia follows certain infectious diseases.
- FCF fibroblast growth factor
- FCE epidermal growth factor
- FCF5 Fibroblast growth factor type 5
- FCQ keratinocyte growth factor
- Insulin-like growth factor I accelerates concentration-dependent hair growth and hair follicles. FCI-I actions are modulated by proteins produced in FCI-binding dermal papilla cells (insulin-like growth factor I binding proteins: PLFCI); The exact mechanism of modulation has not yet been clarified. However, it has been shown that PLFCI-3 (which are the most abundant types of PLFCI in dermal papilla cells) form a complex with free IGF-1 to reduce the concentration of IGF-1 available to stimulate capillary stretching and maintenance. of the anagen phase. Retinoids and glucocorticoids stimulate the production of PLFCI-3 in dermal papilla cells.
- PLFCI-3 which are the most abundant types of PLFCI in dermal papilla cells
- Insulin itself has the same effect as IGF-1; It has been observed that body hair in patients with hyperinsulinism has a male distributional pattern. Substances regulating calcium and phosphorus homeostasis may also be involved in controlling hair growth. Parathyroid hormone (HPT) and the corresponding HPT peptide inhibit hair growth and epidermal cell proliferation. 1,25-dihydroxyvitamin D3 (1,25 / OH / D3) at low concentration (1-10 nM) stimulates, and at higher concentration (100 nM) and after longer contact inhibits hair and hair. hair follicle growth. These HPT and 1,25 / OH / D3 actions require direct contact with the hair follicles.
- HPT Parathyroid hormone
- HPT 1,25-dihydroxyvitamin D3
- 1,25 / OH / D3 actions require direct contact with the hair follicles.
- dermal papilla cells are most affected by 5-sx-dihydrotestosterone (5a-DHT). It is synthesized in these cells from testosterone under the catalytic action of the type II 5-ocreductase enzyme.
- 5a-DHT 5-sx-dihydrotestosterone
