What is CGH?

CGH—short for Concentrated Growth-Factor/“Growth-Hormone” Therapy—is an advanced regenerative treatment derived entirely from the patient’s own blood. After a standard venous draw, the sample is spun in a high-speed centrifuge that separates its components into distinct layers. Just beneath the white-blood-cell band lies a platelet-rich clot teeming with thrombocytes, leukocytes, and a cocktail of bio-active cytokines and growth factors; this densely packed concentrate is the CGH fraction. Because it is autologous, the preparation carries no risk of immune rejection or disease transmission and can be used immediately in outpatient settings.

In hair-restoration practice, CGH is injected in micro-aliquots across thinning scalp zones or along freshly transplanted graft lines. The high payload of platelet-derived growth factors (PDGFs), vascular endothelial growth factor (VEGF), and other signaling molecules wakes dormant follicles, boosts local blood supply, and accelerates tissue repair. Surgeons may also infuse CGH intravenously or mix it with graft-holding solutions to enhance follicle viability during lengthy transplant sessions—effectively giving each graft a biochemical “head start” before it is placed. Compared with standard PRP, CGH delivers a markedly higher concentration of regenerative factors, translating into faster crust shedding, reduced redness, and quicker return to everyday styling.

Clinical data support these benefits: a 2022 prospective study of 60 androgenetic-alopecia patients treated with concentrated growth factors reported significant gains in hair density, follicle count, and shaft diameter, with 93 % patient satisfaction and zero major complications at six-month follow-up.PubMed For men and women seeking a minimally invasive complement—or adjunct—to FUE, DHI, or medical therapies, CGH offers a scientifically grounded path to thicker, healthier hair while simultaneously shortening post-procedure recovery times.
