The possibility of donor hair regrowth after Follicular Unit Extraction (FUE) surgery represents a significant advancement in hair restoration. Traditional FUE methods involve the complete removal of hair follicles from the donor area, often reducing hair density. The Partial Transection Technique offers a promising alternative:

Method: Partially extracts hair follicles, leaving a portion of the dermal papilla and stem cells in the donor area.

Goal: Stimulate regeneration of hair follicles through the remaining stem cells.

Benefit: Aims to preserve donor area density, even after multiple procedures.

Adjunctive Therapies: Platelet-Rich Plasma (PRP) and Platelet-Rich Fibrin (PRF): Concentrated sources of growth factors derived from the patient's blood, applied to promote healing and stimulate hair growth in donor and recipient areas.

Microneedling: Creates micro-injuries in the scalp to enhance absorption of PRP/PRF, scar remodeling and stimulate collagen production, supporting regeneration.

Emerging Potential of Exosomes:

Exosomes: Tiny vesicles released by stem cells that facilitate cell-to-cell communication and tissue regeneration.

Enhancing Results: Exosomes, particularly those derived from mesenchymal stem cells, contain a high concentration of growth factors and signaling molecules that may further enhance hair follicle regeneration beyond what is achieved with PRP/PRF.

Research Outlook: Ongoing studies suggest that integrating exosome therapy could amplify the regenerative processes, leading to improved donor area recovery and hair density preservation.

Specializing in hair restoration, particularly Follicular Unit Extraction (FUE), he moved to Australia and joined DHI Australia. 2019 he was appointed as Director of DHI Internationals Training Academy, he trained international teams until the onset of COVID-19. Returning to Australia, he founded Evolved Hair Restoration, focusing on regenerative and innovative hair restoration solutions.
