What major development in electrolysis occurred in 1945?

In 1945, the major development in electrolysis that took place was the introduction of thermolysis. This technique was significant as it combined the principles of heat and electrical current to effectively target hair follicles for removal. Thermolysis uses high-frequency alternating current to generate heat in the hair follicle, leading to instant destruction of the follicle's tissue. This method was developed as a response to the limitations of earlier electrolysis techniques, allowing for quicker and more efficient treatment.

The advancements in thermolysis contributed to its differentiation from traditional electrolysis methods, which primarily used galvanic current to chemically destroy the hair follicle. The introduction of thermolysis marked a key evolution in hair removal technology, paving the way for various practices that enhanced both the speed and effectiveness of electrolysis. As time progressed, this method became widely recognized and is still employed in modern electrolysis practices today.
