anagen, catagen and telogen. These phases have a significant influence on how
effective the light-based hair removal is.
Anagen is the hair growth phase, while catagen and telogen are both resting phases.
Anagen – growth
Although the duration of a complete hair growth cycle differs from person to person
phase
and depends on the area of the body the hair is gro-
wing on, the cycle generally lasts 18 to 24 months.
At any given time, the majority of the hair follicles on
an area of skin are in the resting phase. The beurer
SalonPro System can have no effect on these resting
hairs.
Catagen – resting
However, the hairs in the anagen growth phase res-
phase
pond to treatment using the beurer SalonPro System.
Please note that a complete hair growth cycle is required to achieve complete hair
removal using the beurer SalonPro System.
Telogen – resting
phase
The beurer SalonPro System is a light-based device for lasting hair removal for
private use. The hair removal process based on laser and light is a well known
and proven method. In 15 years of clinical applications around the world, it has
proven to be a safe and effective method for achieving lasting hair reduction.
How does the light remove the hair?
Light-based hair removal is founded on the principle of selective photothermoly-
sis, which uses optical energy to deactivate hair growth. To achieve such a ther-
mal effect, the hair shaft must selectively absorb the light energy and convert it
into heat.
This selectivity is achieved when the optical energy that is released into the tissue
is mainly absorbed by the pigment of the hair shaft, while the skin and the sur-
rounding tissue remains cool. Melanin is the pigment in the hair shaft that is res-
ponsible for absorbing the light and generates the heat that ultimately deactiva-
tes hair growth. Therefore, the more melanin present in the hair (i.e. the darker the
hair), the more light can be absorbed and the more effectively the light can work
for the hair removal.
What effect does the hair growth cycle have on light-based hair removal?
Every hair on our body goes through the three phases of the hair growth cycle:
