Laser Hair Removal – Answers To Frequently Asked Questions
How does laser hair removal work?
Laser hair removal systems emit a gentle beam of light that passes through the skin to the hair follicle. The hair absorbs it, the energy from the laser is transformed into heat and the hair follicle is disabled.
How does laser hair removal compare with electrolysis?
Electrolysis can be a tedious, painful process destroying each hair follicle one at a time. This can sometimes require treatment over years at regular intervalsn israeli site.
Laser hair removal on the other hand can treat hundreds of hair follicles simultaneously so the process is much quicker.
Is laser hair removal for anyone?
With CoolGlide’s unique design, there is now the flexibility to treat all skin types with laser hair removal. Before CoolGlide, tanned patients and persons with darker skin could not expect good results from laser hair removal treatment.
A CoolGlide device has a longer wavelength which allows it to treat all skin tones. While patients with fair skin still respond the best, medical studies indicated that patients with tanned or dark skin can now achieve hair reduction equal to fair skinned patients without undesirable side effects.
Other Laser Hair Removal Devices
With some laser hair removal equipment, an absolute requirement is that the hair must be darker than the surrounding skin.
White skin with dark hair responds best. Persons with dark, coarse hair are the easiest to treat as dark hair contains melanin, a dark pigment which attracts the laser light so more laser energy is absorbed. Fewer sessions are needed.
Light colored hair is more difficult to treat and blonde and red hair are very difficult to treat requiring multiple laser hair removal sessions with varied results.
Anyone on a diet high in beta-carotene will need to change eating habits if they want best results from laser hair removal. Beta-carotene, found in vitamin A, carrots, squash and other vegetables produces a yellow or orange color in the skin which absorbs the laser energy and interferes with it reaching the hair follicle.
As beta-carotene can remain in the body for months, an adjustment in diet may be needed well in advance of laser hair removal treatment for optimum results.
Persons with light skin are the easiest to treat, requiring less laser hair removal sessions as the results are faster.
Persons with dark skin or sun tanned skin take longer to get results because melanin, the dark pigment in hair, is also present in skin. Melanin absorbs some of the laser light.
There is the danger of dark skin being burned in these instances so a laser beam with a lower energy level is used. For this reason also a higher level of expertise is required on the part of the laser hair removal clinic.
