[Asia Economy Reporter Changhwan Lee] LG Electronics disclosed clinical trial results proving the efficacy of its hair loss treatment medical device, ‘LG Pra.L MediHair,’ on the 21st ahead of its launch.


LG Electronics announced that it recently showcased the LG Pra.L MediHair (model name: HGN1) at the Korean Hair Research Society (KHRS) academic conference. The Korean Hair Research Society is an academic organization composed of researchers conducting hair-related studies, including dermatology specialists.


LG Electronics explained that it introduced the efficacy of LG Pra.L MediHair confirmed through clinical trials commissioned to Bundang Seoul National University Hospital, drawing high interest from attendees. The presentation was led by Professor Changhoon Heo of Bundang Seoul National University Hospital, the principal investigator of the clinical trial.


According to the clinical trial results conducted on 46 adult men and women, the hair density of participants using LG Pra.L MediHair increased by 21.64% per square centimeter (㎠) compared to before use, and hair thickness increased by 19.46%. Participants in the clinical trial used LG Pra.L MediHair in a 27-minute mode three times a week for a total of 16 weeks.


LG Pra.L MediHair is a helmet-type medical device dedicated to hair loss treatment worn on the head. It recently received medical device approval from the Ministry of Food and Drug Safety as a ‘Class 3 medical laser irradiator.’


This product utilizes the Low-Level Laser Therapy (LLLT) method. The LLLT method has been approved by the U.S. Food and Drug Administration (FDA) as a hair loss treatment that helps with androgenetic alopecia.


Energy emitted from a total of 250 light sources, including 146 lasers and 104 LEDs, activates the metabolism of follicle cells surrounding the hair roots, promoting hair growth. It also slows the progression of androgenetic alopecia, which causes a decrease in hair density.


Considering the increasing number of customers concerned about hair loss, LG Electronics developed a hair loss treatment medical device that customers can easily use at home. The new LG Pra.L MediHair product is scheduled for official release within the year.



Osangjun, head of LG Electronics’ Home Beauty Business, said, “We will lead the premium home beauty device market by enhancing LG Pra.L’s unique competitiveness based on safety and efficacy, while introducing various innovative products reflecting customer needs.”
