Generally, it can take between 4 to 8 treatments to get maximum results. However, non-medical
practitioners are allowed to give treatment in salons and they may not be trained to use the proper
settings. Any oversight on their part may cause skin damage, excessive pain or an increased number
of treatments. However, the price of using a dermatologist may be too high for many people.
List of Factors That Affect Frequency of Treatment
Color of the Skin
laser for hair removal works best
on skin that is light in color. Darker or tanned skin can still undergo the procedure but the power
of the laser needs to be reduced. Less power means there's less chance of skin damage but more
frequent sessions which will increase the overall cost of treatment.
Color of the Hair
The darker the hair, the better the results. Brown and black hair will conduct the
energy down to the hair follicle where the heat will zap the hair producing cells. The
darker the hair, the more effective each treatment will be and fewer number of sessions.
Laser treatment on
red hair, or blond or fair hair
won't be effective since those colors tend to reflect the laser light instead of absorb it.
Type of Laser
Before 'going under the laser', patients fill out a questionnaire with the technician
or doctor so that they can determine the type of laser (wavelength of the light) that should
be used and the duration of exposure. For most people, the longer the wavelength, the less
chance there is for skin damage.
Texture of the Hair
Thin hair tends to transmit the most amount of laser energy down to the follicle. An
experienced technician will be able adjust the laser for hair removal to account for
The number of treatments necessary depends in part on how good the technician is at
setting the laser parameters.
Risks of Laser Hair Removal
Incorrect settings will not result in maximum hair-loss.
Using the incorrect laser may put patients at a higher risk of skin damage and burns.
Not applying the laser long enough to the skin will require more treatments which
results in higher costs.
Tips to Reduce Cost
The more lasers the clinic has, the greater the chances that you'll be treated with
the safest and most appropriate machine.
Ask if the machine is rented. If so, run! This usually means that they only do a few
treatments per month and may not have enough training yet. Or they may use the wrong
laser on your skin and hair type.
The Tria laser is a popular at-home unit
that may be effective for some people. It has a finite life-span, around 250 cycles, so
follow the manufacturer's recommendation to get the best possible usage from the device.
How many treatments for laser hair removal depend on the type skin and hair.
It is the responsibility of the clinician or doctor to determine the best technology
to use which will maximize results and minimize the number of treatments (and cost).
But above all else, patients should spend the time and make the effort to find
well-trained individuals before undergoing treatment - treatment will be more
effective, and more affordable, too!
