What Is It and How Does It Work?
These treatments are entirely natural, using a small sample of your own blood to stimulate healing.
Older PRP therapy spins your blood at high speeds and uses chemical additives to prevent clotting. However, this rapid process can quickly deplete the active growth proteins in the liquid, limiting how well it works.
The new breakthrough uses Low-Speed Centrifugation for Fibrin-Scaffolded Growth Factor Release. By spinning the blood much slower and removing all artificial chemicals, the blood naturally forms a sticky biological web called a fibrin scaffold. This web traps active healing cells and slowly leaks highly concentrated growth proteins directly into the hair follicles over several weeks, rather than releasing them all at once.
The Science and the Results
In a new clinical study published in the Journal of Dermatological Treatment, researchers tracked 74 women with female pattern hair loss over 24 weeks. The women were split into groups and received 4 sessions of either PRP, i-PRF, or CGF spaced one month apart.
The clear results from the study:
-
Double the Growth: Women using CGF achieved a 27.11% increase in thick, visible (non-vellus) hair, and those using i-PRF saw a 26.54% increase. Meanwhile, traditional PRP only managed a 14.53% increase.
-
Better Thickness: All three groups saw a significant improvement in the actual diameter (thickness) of their hair strands.
-
Safer and More Comfortable: The i-PRF group had the lowest rate of side effects (such as redness or swelling), making it the most comfortable option tested.
-
The Power of Blood Vessels: The study discovered that the level of a protein called Vascular Endothelial Growth Factor (VEGF)—which helps grow new blood vessels to “feed” your hair—had a direct, positive correlation with the amount of new hair grown ($r=0.527$, $R^{2}=0.278$, $p<0.05$).
| Treatment Type | Average Hair Increase % | Side Effect Rate |
| CGF | 27.11% | Low |
| i-PRF | 26.54% | Lowest |
| PRP (Older Method) | 14.53% | Moderate |
When Can You Get It?
Because these treatments are “autologous” (meaning they use your own blood and require no synthetic drugs), they do not face the long approval delays of new pharmaceuticals. Advanced hair clinics are already offering i-PRF and CGF therapies across the globe.
How you can benefit from this treatment now
If you are considering PRP therapy to treat thinning hair, you can benefit today by asking your dermatologist or hair clinic if they offer i-PRF or CGF instead. These next-generation methods are safer, produce less discomfort, and are clinically proven to grow twice as much thick hair as traditional PRP.
