Does Laser Hair Removal Really Work Permanently?
Laser hair removal provides the best mix of hair reduction and very little fuss, but even though it is very efficient, it is not really permanent. Laser hair removal can bring about a reduction of up to 90% of hair on the treated area. It is a basic, quick treatment which involves shining laser light to the hair follicles which slowly warms the follicle until eventually it is incapable of growing new hair. Originally, this worked best for individuals with light skin tone and coarse dark hair, because the melanin in darker hair was more effective at transforming light into heat, but newer laser light technologies are working for all skin and hair types.
The reason laser hair removal isn't entirely permanent is due to the way in which hair grows, and also the healing power of the human body. There are several cycles of hair growth - active, regressive, and resting - and any hair in the resting or regressive cycle usually are not developed enough for the laser to affect them. This is the reason several treatments are usually necessary to reach the results you want, otherwise hairs in the resting cycle will shift into the active cycle and start developing all over again. Happily, you can avoid this concern just by going back for an additional round of treatments, until all the hair follicles have been taken care of.
Due to the way the body repairs itself over time, it is possible that a few new follicles will develop and grow hair, but this hair is usually much finer and of a lighter tone, which makes it less obvious - but if you still prefer to get rid of it, you are able to just go with another treatment. Currently, this is the simplest hair removal remedy that modern technology has been able to create.
At the moment, the sole hair removal treatment which the FDA considers "permanent" is electrolysis, which happens to be an incredibly intricate process that involves sliding needles into the skin and electrocuting your hair follicles to death - far from a great option, and affected individuals will always be subjected to mild to extreme suffering, and procedures normally take nearly 4 years (yes, that's right - four YEARS) to perform.
