RF microneedling delivers the thermal effect of RF to the desired skin layer by inserting needles into the skin in a controlled manner.

Considering the thermal effect of RF, which causes tissue denaturation or coagulation, and the physical damage of the needles, there may be concerns about hair follicle damage in terms of the safety of hair loss treatment.

However, one pre-clinical study conducted by Dr. Jongju Na, et al. in 2015 in a porcine model confirmed that RF microneedling did not damage hair follicles1, while another pre-clinical murine study conducted by Hyunjo Kim in 2018 confirmed the same2

By using the appropriate pulse duration and power, RF microneedling can stimulate the hair follicles and improve hair loss by increasing blood circulation and cytokine production in the surrounding area. Moreover, when the drug is applied immediately after SYLFIRM X, the open channels created by microneedling increase drug penetration, and the skin subjected to RF heat action is more receptive to the drug action.

To verify the effectiveness of SYLFIRM X hair loss treatment, patients were treated with only the device without applying any drugs or hair loss products. As a result, it was confirmed that hair count and hair thickness were improved even with SYLFIRM X treatment alone. Nevertheless, hair loss is not a simple problem of hair, but a result of complex causes and factors, and for the satisfaction of patients who expect a faster and better effect, combination therapy using SYLFIRM X and hair loss products is predominantly performed in my clinic.
