30 September 2013As well as only being temporary, for some people, methods of hair removal such as shaving and waxing can also come with their own side effects. For a more permanent solution, and to avoid unpleasant irritation, many people turn to Laser Hair Removal. It is suitable for both men and women, but beyond safely removing unwanted hair many people do not know how it works.Here is a quick guide:How does it work?The laser is attracted to melanin, which gives hair its colour, and tracks this pigment to the root of the hair. Here it generates energy and damages the cells. This provides a permanent reduction in hair growth and thickness. As this treatment can only target the hair that currently grows, a course of sessions is usually required to guarantee a long-lasting final outcome.What systems are available?The lasers commonly used are Alexandrite, Diode and Nd-Yag systems.Does it hurt?Patients often say the feeling is similar to that of being lightly snapped with a rubber band. Newer lasers have in-built cooling systems to lessen what mild pain there is.What should I do afterwards?Your skin may be red for a couple of hours following treatment. It is also best to avoid sunlight, steam (such as a sauna) and facials for a day or two. Always use a sunblock (SPF 30 and above) on the area you are having treated.How many treatments will I need?Ideally, a minimum number of six treatments are required. Intervals between treatments can range from four to six weeks.
