It is one of the fields where platelet growth factors have the clearest rationale: many studies proved that in NON-CICATRICIAL alopecia types (alopecia areata, androgenic alopecia) a significant quantity of residual stem cells remains in the skin, not able, however, to stimulate bulb growth.
Consequently, the stimulation by platelet GFs can lead to a significant hair regrowth. Stimulation of hair bulbs is determined by the regular tissue repair process. Results have proved to be comforting in more than a thousand treated cases.
According to the life cycle of the treated bulb (hair, eyebrows) the treatment interval varies.
As for hair transplantation, we always perform a PRGF treatment during surgery, and another one two months apart.
The purpose of using PRGF in hair transplantation is to stimulate a better and faster engraftment of the bulbs and the growth of possible new bulbs, and to favour a rapid healing process halving wound and recipient site healing time.
OUR PROTOCOLS FOR THE TRICHOLOGIC TREATMENT:
Androgenic alopecia: 2 treatments, three months apart, and in case a third treatment according to the clinical response after approximately 4 months.
Alopecia areata: 3 consecutive treatments three months apart from each other for the hair, one month apart from each other for the eyebrows.
Chronic AA, multiple patches, non respondent to therapies
15 patients treated with PRP only one patch / then all patches
15 patients treated with Triamcinolone, intralesional i.
15 patients not treated
3 external dermatologists evaluators
