Thermolysis is a process that involves the breakdown of chemical compounds through the application of heat. This method is often used in various scientific fields, including chemistry and biology, to decompose substances into simpler components. The heat causes the bonds between atoms to break, resulting in new products. In the context of laser hair removal, thermolysis refers to the use of heat to destroy hair follicles. This technique is effective for reducing hair growth by targeting the follicle with thermal energy, which damages it and inhibits future hair production.
