LASER HAIR REMOVAL PROCEDURE
Once we have decided that you are a good candidate for laser hair removal, we will proceed with the treatment by ensuring that all surface hair has been shaved prior to treatment. Should any hair be left on the surface, the laser would target the hair at the surface as oppose to the root of the hair which would defeat the purpose of the treatment. Assuming there is a nice clean shave and that there is a contrast between the skin and the hair, the laser will damage the root of the hair leaving behind a stem.
Over the course of 2 to 3 weeks post treatment, many of the hairs will appear as if they are growing which actually the skin is naturally pushing this stem up and out. If you were to pull at these hairs 2 to 3 weeks post treatment many of these hairs would simply fall out with no resistance at all. Once many of these hairs fall out, most clients appreciate that there is little hair in between treatments which is nice.
Treatment intervals are 4 to 6 weeks for the face and 6 to 8 weeks for the body which is based on the stages of hair growth. 5 to 8 sessions are required for best results. The laser feels like a small pinch.
Post treatment the skin will be slightly sensitive. Perifollicular swelling and erythema are normal immediately after treatment. Although this irritation tends to subside fairly quickly, we do recommend avoiding any hot water, exercise and friction to the area as the heat dissipates from the hair follicle.
How does Laser Hair Removal Work?
Have you ever tweezed a hair from your head or body and noticed that sometimes it has a large bulb, sometimes it has a clear root and at other times it has no root at all? What you are witnessing is the stages of hair growth. Laser hair removal is a process. The reason why you require multiple sessions is due to the fact that every hair on the human body grows in cycles. The 3 cycles of hair growth are the anagen stage (growing stage), Catagen stage (the hair shaft is separating from the papilla) and the telogen stage (the hair is completely inactive and detached from the papilla).
During the anagen or growing stage, the hair is attached to the hairs’ papilla. The dermal papilla is located at the root of the hair and contains the blood supply, which nourishes the hair follicle, and the matrix, which consists of cells that actually form the hair shaft. By damaging the root of the hair while it’s growing, we can prevent the hair from re-growth. Laser hair removal works on the principle of selective thermolysis. The chromophore or target for laser hair removal is pigment which is why the greater the contrast between the skin and the hair, the better the results. The laser seeks the dark pigment within the root of the hair and generates heat. This heat damages the hairs in the anagen or growing stage of hair growth. Since the hair is only permanently eliminated during the anagen stage and considering only 10 to 20% of the hairs are in this anagen stage with every treatment, a series of treatments ensures best results.
