Permanent hair removal is a scientific means of permanently destroying body hair from its developmental area through methodical applications. Shaving is the most useful method for a person. Another way is sugaring: a proportional paste mixture is smeared and tied with a zipper using a porous cloth. The waxing process is a resin-based root follicle treatment, but it is not suitable for permanent hair extraction. As a result, this technique quickly became obsolete.
Electrolysis is another hair removal method that uses a needle with an electric current to damage all the hair strands in the follicle. Laser hair removal is widely used, which has been shown to be better or as effective as electrolysis. You can get full information on permanent hair removal at https://strip.com.hk/laser/.
Selective photothermolysis (SPTL) is the principle underlying laser technology. Hair follicles are reached by light (wavelength) and duration (pulse width) and the results are optimized. This method is accepted for its speed and success in permanent hair removal. In laser technology, the duration (pulse width) is crucial.
With darker skin, the longer pulse width is safer, and in other skin types, a short pulse width deactivates the hair follicle. Many sessions are required on a regular basis, but this will depend on the area of the body being treated. The face requires frequent interventions three to four weeks apart, while the legs take less time.
