Laser hair removal offers the very best combination of hair reduction and the bare minimum fuss, but while it is quite effective, it is not really permanent. Laser hair removal can lead to a reduction of up to 90% of hair on the targeted region. It is a simple, quick treatment method which involves shining laser light to your hair follicles which gently heats the follicle until it is not capable of growing new hair. Originally, this performed best for folks with light skin color and coarse dark hair, as the melanin in darker hair was more effective at transforming light into heat, but more modern laser light systems work with all skin and hair types.
The reason laser hair removal isn't totally permanent is because of the way hair develops, and the healing power of the human body. There are various cycles of hair regrowth - active, regressive, and resting - and any hair in the resting or regressive cycle are not developed enough for the laser to affect them. That's why several treatments are typically required to get the effects you want, or else hairs in the resting cycle will push into the active cycle and begin growing again. Fortunately, you can avoid this issue by simply returning for the following round of treatments, until every one of the hair follicles have been treated.
Because of the way the body heals itself over time, it is possible that a few new follicles will develop and grow hair, but this hair is generally much finer and of a lighter shade, making it less noticeable - however, if you still prefer to get rid of it, you are able to just go for an additional treatment. At this time, this is actually the simplest hair removal remedy that scientific research has been able to develop.
At this time, the only hair removal treatment method which the FDA considers "permanent" is electrolysis, which is a very tricky process that consists of slipping fine needles into the skin and electrocuting your hair follicles to death - certainly not a pleasing option, and users will always be subjected to mild to serious pain, and procedures may take as much as 4 years (yes, you better believe it - four YEARS) to perform.
