Is Laser Hair Removal Really Permanent?
Laser hair removal is the most effective mix of hair reduction and the least fuss, but while it is effective, it is not totally permanent. Laser hair removal can bring about a decrease of as much as 90% of hair growth on the targeted area. It is a basic, convenient treatment method which involves applying laser light to the hair follicles which gradually warms the follicle until finally it is incapable of growing new hair. At first, this functioned best for folks with pale skin tone and coarse dark hair, as the melanin in darker hair was far better at turning light into heat, but newer laser light technologies work for all hair and skin types.
The reason laser hair removal is not totally permanent is due to the way human hair grows, and also the healing ability of the human body. There are certain periods of hair regrowth - active, regressive, and resting - and any hairs in the resting or regressive cycle aren't developed enough for the laser to affect them. That is why several treatments are usually needed to reach the results you want, or else hairs in the resting cycle will go into the active cycle and begin growing all over again. Thankfully, you can avoid this concern by just going back for the following set of treatments, until finally every one of the hair follicles are treated.
Because of the way the body repairs itself over time, it is possible that a small number of new hair follicles will develop and grow hair, but this hair is frequently much finer and of a lighter tone, that makes it less noticeable - but if you still need to get rid of it, you are able to just go for a further treatment. These days, this is the simplest hair removal treatment that scientific research has been able to develop.
At the moment, the sole hair removal treatment that the FDA identifies as "permanent" is electrolysis, which happens to be an incredibly tricky procedure that calls for slipping fine needles straight into your skin and electrocuting your hair follicles to death - far from a great option, and affected individuals will almost always be put through mild to serious discomfort, and procedures normally take up to 4 years (yes, you got it - four YEARS) to finish.
