Laser hair removal is a technique that was first commercially used in the 1990’s, although people had been experimenting with it from the 70’s. Basically it’s the damaging of the hair follicle, by the generation of heat, through the concentrated application of light energy. The melanin in the hair follicle, being dark, absorbs the heat and kills the germ cells in the follicle.
The effectiveness of the treatment has now been widely accepted by the dermatological fraternity, and the treatment is widely available, through doctors and skin care clinics, throughout the country.
Are there Different Kinds of Lasers used?
Indeed, there are quite a few different types of lasers used worldwide. Lasers emit wavelengths of energy, which stretch from visible light to near infra-red. They are named after their varying sources of wavelength. Hence, ruby, alexandrite, pulsed diode array, Nd:YAG:, and finally IPL (intense pulsed light), which is funnily enough, not a laser.
Studies done on the efficacy of the varying types of laser also highlighted a very important fact: that the length of time of the pulse was critical in killing the required cells in the hair follicle. So, it’s not only important how much heat is generated, but also, for how long the heat is applied.
Isn’t this going to be very hot?
There are various types of cooling systems that are used, to cool the surrounding skin, during treatment. They are:-
- Contact cooling
- Cryogen Spray
- Air Cooling
So, there is no need for you to worry too much about the heat.
So why have Laser Treatment?
Many people worldwide have hair in unwanted places. For example, if you’re a woman with a heavy moustache, you are obviously not going to let it grow. Or, if you are a guy with a very hairy back, you’d sure like to get rid of the hair. Now, you only have so many alternatives to remove the hair.
Shaving– which makes the hair grow stronger and more vigorously, and is temporary.
Waxing– which is PAINFUL and also temporary.
Tweezing– ditto the PAINFUL and the temporary.
Electrolysis– This involves inserting an extremely fine wire into each follicle and applying an electrical current, to create the heat, which will do sufficient damage to the follicle to prevent hair growing again. And finally…
