Radiofrequency Current at 448 kHz for Female Pattern Hair Loss: Cellular Bases for Redensification Improvement

The study "Radiofrequency Current at 448 Khz For Female Pattern Hair Loss: Cellular Bases For Redensification Improvement" involved 20 patients and explored the effectiveness of Capacitive-Resistive Electrothermal Therapies (CRET) in treating Female Pattern Hair Loss (FPHL). After ten 20-minute CRET sessions over 8 weeks, trichoscopic analysis showed a significant hair redensification (10 - 15 % over pre-treatment values) in all treated scalp areas. In-vitro electrostimulation also significantly increased Dermal Papilla Cells (DPC) proliferation and expression of proteins involved in cell proliferation. The study concluded that 448-kHz CRET could be effective for hair redensification and hair loss prevention.
