The removal of hair is certainly nothing new. Both sexes of the ancient Egyptians removed all body hair bar their eyebrows! It was common practice for these ancient people to don wigs – the upper classes wore wigs of human hair whereas the lower echelons wore wigs made of vegetable fibre.
Laser hair treatment boasts a long and interesting history. It should therefore not surprise one that the history of laser hair removal is an unexpectedly long one.
Invented in 1960, the laser was used to remove unwanted and excessive hair as early as the mid 1960’s – which means that there has been at least fifty years of nasty, unwanted hair being destroyed and beamed through the use of light; although lasers were only approved for commercial use in 1997.
The very first laser hair removal systems were unsophisticated and were not only laborious, but were rather inefficient and could only be used on very light skin tones to remove extremely dark hair,
A ruby-based laser was the first invention which had a short wavelength; the result was that patients with darker skin experienced unpleasant results – the laser would heat up both the hair follicles as well as the surrounding skin – which naturally resulted in some serious burns being sustained.
Furthermore, early lasers were unable to target numerous hair follicles at one time; a most limiting experience and no better than other hair removal methods.
About laser hair treatment:
Laser hair treatment is perceived as being the most advanced method of removing hair in today’s world.
The cosmetic laser has revolutionised the way that society views and approaches grooming.
The beauty of laser is that instead of every single pore being treated individually – lasers beam light into complete areas of skin, which in turn affects every single pore in the targeted area.
The melanin in the follicle of the hair absorbs the light which in turn is transformed by heat through a process called photothermolysis.
The heat is then collected in the surrounding cells that are hair-generating and disturbs any future hair growth.
Most common areas that benefit from laser hair treatment:
The areas that most commonly benefit from laser hair treatment are the legs of females, underarms and the bikini area.
Hair actively grows in these areas for about four to six weeks – it then remains as mature hair for a further six months until new hair grows; for laser hair treatment to be effective the laser has to strike the hair follicle during the anagen phase.
Because only a small percentage of hairs are in the anagen phase at one time, treatments must be spaced out every 4-6 weeks to successfully hit every hair as it enters the growth stage. Usually six to ten treatments are required for maximum results.
Understanding the hair growth cycle is important – this is because there are numerous problems that can arise with one’s hair. The hair growth cycle consists of three diverse stages – these are the anagen, catagen and the telogen phases.
Laser hair treatment is popular because of its speed and efficiency, although some of the effectiveness is dependent upon the skill and experience of the laser technician, and the choice and availability of different laser technologies used for the procedure. Some will need touch-up treatments, especially on large areas, after the initial set of treatments.
