Permanent hair removal laser 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.

Hundreds of hair follicles can be treated simultaneously so the process is much quicker than electrolysis which can be a tedious, painful process destroying each hair follicle one at a time.

This method is quite safe. It uses a wavelength of light which passes through the skin. Unlike x-rays, there is no residual left in the body.

Skin may appear pink or red after treatment. This disappears - in some cases after some minutes, in other cases after a few hours, or in still other cases, a few days. Use of cold packs will speed up the recovery time.

Those Best Suited For Permanent Hair Removal Laser

Coolglide Technology

With CoolGlide's unique design, there is now the flexibility to treat all skin types. Before CoolGlide, tanned patients and persons with darker skin could not expect good results from laser 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 undesireable side effects.

Other Laser Hair Removal Devices

With some laser 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 sessions with varied results.

Anyone on a diet high in beta-carotene will need to change eating habits if they want best results. 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 for optimum results.

Persons with light skin are the easiest to treat, requiring less 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 clinic.

Length Of Permanent Hair Removal Laser Sessions

This varies from person to person with skin, hair coloring and coarseness of hair all affecting the time.

Here are some estimates which can give an approximate guide.

At least 2 or 3 permanent hair removal laser treatments are necessary, and hair that has been waxed or removed with tweezers could need from 5 to 8 treatments.

Photo-Epilation

Photo-Epilation or pulsed light devices use the same principle as in permanent hair removal laser but they are not lasers. An intense pulsed light is used to disable hair follicles with minimal side effects.

It can be effective in hair removal but requires a higher level of skill in operating as it is more difficult to adjust than lasers.

Due to it's larger spot size, large areas of the body such as the back or legs can be treated rapidly. One study showed a 50 to 60 percent clearance of hair in 12 weeks.

Miscellaneous Notes:

Pain varies from person to person depending on their sensitivity. Some have described the sensation to a slight sting on the skin. Others say it feels like a pinch on the skin.

After the first treatment hair will gradually fall out over the next two months. Repeated treatments are necessary to catch all the hairs in their various stages of growth.

The cost depends on the size of the area needing treatment. A consumer guide on permanent hair removal laser gives $500 per treatment session as a reasonable average with 3 to 4 sessions often necessary. Individual consultations are necessary to establish accurate pricing.

As for guarantees, due to the variables involved it is impossible to predict exactly what the results will be for any individual. Many reputable permanent hair removal laser clinics avoid giving guarantees for this reason.
