Whether 100% depilation of the body area is successful depends on the complexity and variety of individual people and their body and health profile. Last but not least, the result of a successful treatment depends on the effectiveness of the diode laser system used for the treatment and the competence of the person performing the treatment. Laser treatment can only be particularly successful if the treatment is carried out in accordance with the instructions. In principle, certain illnesses, medication or changes in hormone status are considered hair growth stimulants. This means that areas of the body that have been successfully depilated can, under certain circumstances, show renewed hair growth, but only from follicles that were previously completely inactive. According to the current standard of knowledge and technology, a depilation rate of 80 % – 90 % is generally achieved for a period of approx. 5 – 7 years.
