Laser hair removal may or may not be permanent. Most of the unwanted
body hair is reduced, but since there are thousands of hair follicles on the
skin, some hair may grow back in a few months or even years after treatment.
How long the results last depends on a person's skin and hair type.
Most people will see at least an 80% reduction in density. The hair
re-growth is also usually thinner, finer and lighter in color compared
to how it was at the start of the treatments.
Why Does Hair Regrow after Laser Treatment
Not all hair strands are in the same growth stage at the same time.
Multiple laser treatments are necessary to burn the hair follicles since
the treatments only work when they're in their mature stage. Due to the
high number of follicles needing to be 'zapped', more than a single session
is required to deaden as many as possible.
In addition, the body is constantly rejuvenating itself and some follicles
that were only marginally affected could start regrowing as a thinner hair fiber
a few months later. Talk to your clinician about follow-up treatments that
may be necessary since this obviously adds to the overall cost.
How Long Can I Go Between Subsequent Treatments
Every valid candidate for laser hair removal will see a hair reduction
after a few sessions. However, some may require a touch-up appointment a few
months later while others may not need follow-up treatments for years. Those
people who use
the Tria at-home laser
will also have to do periodic treatments to see the best results.
The good news is that in the interim, it will not be necessary to
constantly shave, pluck or chemically rid yourself of unwanted hair.
Go to a reputable laser hair treatment clinic or salon and ask an
experienced clinician, "How long does laser hair removal last?" They will
be able to determine how effective the
laser for hair removal will be for your skin and hair type.
