Which method was first used by Dr. Michel in 1875 to remove hair?

The method that Dr. Michel first used in 1875 to remove hair was electrolysis, utilizing galvanic current as part of that electrolysis process. Electrolysis, specifically, refers to the technique of using an electrical current to destroy hair follicles, preventing future hair growth.

Dr. Michel's pioneering work established electrolysis as a reliable method for hair removal, which marked a significant development in the field of cosmetic procedures. The makeup of electrolysis involves the application of a galvanic current, which generates lye to chemically destroy the hair follicle, thus effectively preventing regrowth.

Laser therapy is a more contemporary advancement and was not utilized until much later, following the invention of laser technology. Therefore, while galvanic current is indeed an essential component of electrolysis, it’s the broader classification of electrolysis that encompasses this historical method. Hence, the focus on electrolysis as the correct method aligns well with Dr. Michel's contributions in 1875.
