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.



  • 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.
