Only one observational study compared wet and
dry shaving. The comparisons also included
electrical clipping the evening prior to, or the day
of surgery. The results of this study favoured the
use of electrical clipping the evening before
surgery, or electrical clipping the evening before
reduction in hair growth, as the laser will only damage the follicles in the growth phase. It is difficult
to predict individual responses as many factors are involved: the thickness of hairs, different sites
on the body, hormonal differences, darkness of hairs and how strong laser light can be tolerated.
However, in general the hair-free intervals gradually lengthen and the regrowth becomes sparser
and finer.
What are the risks and benefits of having laser treatment?
Laser treatment may make the underlying skin colour darker or lighter. Any darkening (due to
formation of brown pigment) usually fades over 6-12 months. If the skin is made paler, this may be
permanent. The risk of pigmentation is greater with darker skin tones and tanned skin, which is
why we can only offer laser hair removal to lighter skin types with no tan.
Blistering and crusting of skin sometimes occurs. If this happens, you must not pick or scratch the
area to avoid permanent scarring.
The laser beam will damage eyes if viewed directly without protection.
Is there any preparation I need to know about?
You must avoid bleaching, plucking or waxing the hair for 4-6 weeks before treatment. The
melanin containing hair must be present in the follicle as it is the "��target"�� for the laser light. We
know this may be difficult for you, but it is important for good results. If you shave, it is best to
shave 2 days before treatment.
Avoid the sun for 4-6 weeks before and after treatment, and during any treatment courses. You
may develop hypopigmentation (white spots) after treatment if skin is tanned. The use of selftanning
products must be discontinued one week before treatment.
If you wear make up on the treatment area, please bring along the lotions to remove it. Treated
skin must be clean and dry.
What happens before treatment?
When you arrive you will meet the member of staff treating you. This may be a nurse or a doctor.
They will explain the treatment for you, and obtain a written consent from you unless this already
has been done on previous clinic visits.
Photographs may be taken of the area to be treated so that progress can be monitored. These will
be kept in your hospital notes.
