The Truth About Laser Hair Removal
By Virginia Wong
There are many different techniques to remove unwanted hair. Some of these include waxing, shaving, coils, electrolysis and laser. Although each has its advantages and disadvantages, they all perform the same function. That is removing unwanted hair.
One such technique that has become quite popular these days is laser hair removal. This technique works by using a laser on the hair at a specified wavelength that emits a specialized light. The light from the laser is passed through the skin and is absorbed by the hair follicle. This light actually targets the melanin (colour) in the hair follicle and damages it, thereby causing the hair to fall out. Interestingly, the use of certain laser for removing hair has been approved by The Food and Drug Administration (FDA). Although the technique is popular, there are advantages and disadvantages of using this method.
Advantages of Laser Hair Removal
The process has advantages in that larger areas can be treated. In addition it is also safe enough to be used on all parts of the body such as the face, back, underarm, bikini line, legs and arms. Compared to electrolysis, it is less painful as the laser only causes a slight burning sensation compared to the needle prick feeling of electrolysis. Unlike shaving or waxing, is usually long lasting.
Disadvantages of Laser Hair Removal
One disadvantage for is that not everyone is the perfect candidate for this type of treatment. Those with lighter skin and dark hair have a much higher chance of permanent hair removal than grey, red or blonde hair. In addition, those with dark skin or who are tanned are also not good candidates as the laser may cause damage to their skin due to high pigment levels. The reason being is that dark hair contains a pigment called eumelanin which effectively absorbs more laser energy and therefore results in more effective destruction of the hair follicle. Due to the higher effectiveness of the treatment towards dark haired fair skin patients, it leads to fewer treatment and is therefore less costly. Other the other hand, grey, red and blonde hair contain a pigment called pheomelanin that absorbs less laser energy reducing the effectiveness of the treatment. Therefore extra treatment is required for the same effect. So before you sign up for this treatment, make sure you know the principal of this treatment. If you are not an ideal candidate, be prepared for extra treatment charges.
