Traditional methods of hair removal such as tweezing, waxing, shaving and using epilators are passé; hair removal today is all about using advanced technologies to remove hair permanently. One of the most effective processes is laser hair removal. The basic principle of this is exposing hair to pulses of laser light that destroys the hair follicle. While laser hair removal has been in the experimental stages for more than a couple of decades, it has been commercially used since the late 1990s only. These devices are now installed in leading salons and spas and the smaller portable ones can be purchased by individuals to be used in homes.
The technical aspect of laser hair removal is as follows. Intense specific light beams target the area under treatment and since dark objects absorb light energy better, laser treatments work best on black or dark brown hair that are coarse in texture. Melanin occurs naturally in skin and is primarily responsible for skin and hair colour. It is present in follicles, the area that facilitates hair growth. Through laser light energy, follicles are damaged thereby stopping further growth of hair in that region. Even though laser has traditionally worked best on dark hair fair skin patients, new innovations have made laser processes equally effective on those with dark hair and dark skin.
Laser hair removal has become very popular because of the speed of treatment and affordability. A lot of course depends on the type of laser technology of the devices being used and the skill of the operators. A full course is usually spread out over 3-8 sessions at monthly intervals. Patients may need minor retouches at a later date. Each pulse of light is emitted at a fraction of a second speed and can treat a target area with several strands of hair simultaneously. The total time per session is dependent on the size of the target area. Hence, large areas like the legs can take up to an hour while smaller areas like the upper lip are done in under a minute.
Before going on to the actual procedure of laser permanent hair removal, a word about another light based technology for permanent hair removal will be in order. It is IPL or Intense Pulsed Light. It is a cheaper option to laser processes and is considered to be less effective. While laser devices sends out a specific beam of light that hits the melanin in hair follicles, IPL run equipment sends out broad scattered beams of light. Hence the power of individual light beams is less than that of laser. However, IPL based equipment is widely used in top end beauty salons and spas and it is also possible to purchase a small hair removal IPL machine for sale for personal use.
Laser based hair removal treatments are safe, painless and without any side effects. There is usually a stinging sensation during the process but this is taken care of by using cooling gels or passing cool air over the area being treated. After the process is over, ice packs and anti inflammatory creams are applied to ease the initial discomfort.
Laser hair removal equipment has now come of age. There is a huge demand for such devices in Australia which is today one of the fastest growing markets in the world for beauty care. This demand is more than adequately met by Australian Aesthetic Devices, one of the leading importers and distributors of laser equipment in the country.
