Well this is one of the earliest uses of the medical laser for a number of reasons; primarily because hair is a BIG issue to a lot of people. Especially unwanted hair!
Lasers are one of the most effective ways of getting rid of unwanted hair. I often say to people; electrolysis is like mowing a lawn with a pair of scissors one blade at a time. It takes a long time and by the time you get to the end of the lawn it’s started growing again at the other end!
Lasers are like a lawn mower. They go down and shwooosh – and not only do they cut the grass, a percentage of the hairs are permanently destroyed. It’s called “Permanent Hair Reduction”.
What most people hear is “permanent” but you must remember I also said “reduction”. In other words not ALL hair is gone, but it is reduced.
It’s reduced in number and it’s reduced in size. The bottom line is that you’re going to look better and that’s what counts. It can take 4-8 treatments for laser hair removal to be effective. Generally the most successful candidates for laser hair removal have dark, coarse hair on light coloured skin.
The principal behind laser hair removal – if you can imagine my arm is a hair sitting in the skin the laser light goes through the skin like light through glass, hits the hair in the follicle, heats it up for a few milliseconds. Just fractions of a second, heats it up so it scorches the lining of the hair follicle and when you scorch the lining of the hair follicle – and we don’t fully understand why but – it tends to permanently destroy the hair.
The reason you need more than 1 treatment is because hair is in three different phases of growth at any one time – resting phase, growing phase, shedding phase. It’s only the big fat hairs in the growing phase that really respond to the laser, so that’s why you have to come back time and time again.
I’ll tell you now white hairs are very difficult to treat with laser; there are some lasers that claim to treat them… it CAN work, I’ve seen it work, but I wouldn’t hold your breath. So I don’t tend to promise much for people with white hair; I tend to say go waxing, go dissolving, go electrolysis.
Electrolysis still has a place in all this but if you want to get rid of a lot of hair quickly…
