Laser Hair Removal: Benefits and Procedures
As a concept, permanent hair removal refers to the permanent elimination of hair. But the more
accurate definition in this case would be permanent waxing. Firstly, genetic and familial factors, as
well as individual factors, influence whether hair on the body increases or not. Every human being has
a certain number of hair roots scattered throughout the body, but only some are active, others remain
dormant and do not produce hair. These passive hair follicles, which fail to produce them, can be
activated both for physiological reasons (involving the use of certain medicines such as cortisone)
and even pathologically, especially those of endocrine origin. So there are parts of the body like the
armpits or the pubic area, which are controlled by individual hormonal secretions. It is precisely for
these reasons that it is almost impossible to permanently remove hair from the body unless some
medicines are taken simultaneously that neutralize this hormonal influence. Therefore, the correct
determinant is not correct, but it must be permanent, so the result is permanent over time compared to
the treated active roots. After a correct treatment cycle, in some subjects, the results can last for
more than a year. However, to consolidate these results, cyclic maintenance sessions are necessary,
every 2-5 months.
1) WAXING OR EPILATION: What's the Difference?
The term waxing refers to hair removal on the skin. For example, men remove their beard and this method
is called waxing. While epilation consists of completely removing the hair, also removing its root.
Tweezers and pliers are the most commonly used tools for epilation. Laser pulses and pulses, although
they do not mechanically remove hair from the skin, emit a pulse of light, which penetrates the skin,
regenerating its root through heat, and this process is called epilation or root scrubbing, not waxing.
2) LASER OR PULSED LIGHT: Ways to Remove Hair
The laser system and the pulsed laser system are characterized by two different physical mechanisms that
emit pulses of light and respond to the specific area of the skin where the hair roots are located. It
is not possible to decide in advance whether it is better to use a laser or a pulsed light to treat
excess hair. Some scientific papers have been published in the literature showing similar performances
between lasers and pulsed lights. The assessment of the person's phototype and the typology of the
treated hair (color diameter, density, etc.) and a correct use of the tools are indispensable elements
for permanent and optimal hair removal. Not all pulsed light systems and not all lasers are the same.
Therefore, different and personalized settings are necessary based on the technical characteristics of
each device. Today there are some small buttons for home use, but the results cannot be compared to
professional devices. Moreover, if used improperly at home, the tools may risk burning. Laser and pulsed
lights can be used both by the doctor and by the beautician, provided that the latter has ensured that
appropriate theoretical and practical education is recognized by the competent state institutions to
operate subsequently with this method.
