14 things to know if you might be afraid of laser hair removal (part 1/2)
Part 1 of 2
How does laser hair removal work?
Hair removal lasers target pigment (colour). The specific wavelengths used are capable of detecting colours from light brown through to black. The laser removes hair by targeting the pigment (colour) of the hair, traveling down the shaft of the hair to the root so it can discharge its energy and destroy the root of the hair.
My hair is Blonde/Gray/Ginger. Will laser hair removal work for me?
Unfortunately not. As we talked about above, the laser requires a pigment to work and hair with little or no colour cannot be detected.
I am black. I’ve been told I cannot have laser hair removal. Is this true?
No. Dark skins can be safely treated with a so-called YAG laser which operates at a different wavelength from the more common Alex (alexandrite) laser. This wavelength is not harmful to even very dark skins. We have successfully and safely treated people of all skin colours.
May I have laser hair removal when pregnant?
There is no evidence that laser treatment will damage an unborn child. The laser doesn’t penetrate deep enough to cause any harm. Having so said, at Tropicalaser we will not treat a pregnant woman without the written consent of her physician.
How many treatments will I need?
Laser hair removal requires multiple treatments. We recommend a course of 8 treatments to start with. The reason multiple treatments are required is that only hair in the anagen phase can be destroyed by the laser. (When hair is in the anagen phase, the root of the hair is still attached. In the other two phases, catagen and telogen, the hair has detached from the root.) The percentage of hair in the anagen phase varies, depending on the body part, ranging from about 20% on the legs to 35% on the face, hence the need for a course of treatment. The number of treatments is also dependent on a number of other factors, most importantly, adherence to schedule, colour of skin and hair, the thickness of hair, and ability to tolerate small incremental increases of energy between treatments.
How often do I have to come for treatment?
We recommend treatment every 4 – 8 weeks. At the start of your treatment, we will suggest shorter intervals, but as your hair diminishes, we will lengthen the intervals between treatments.
Is it really permanent
The short answer is yes. Laser hair removal does remove hair permanently. The longer answer is yes, laser hair removal is permanent but may not remove every single hair on your body. As we talked about above, light, fine hair will not be removed. Also, we may never catch every last hair in the anagen phase. And it should also be mentioned that normal hormonal changes can cause brand new hair growth which will have to be treated during touch-ups.
Is it painful?
Sorry – this will have to wait for my next blog. In the meantime, if you can’t wait to find out the answer to this and many other questions, please contact us at (780) 705-6370 to schedule your free consultation.
