Long-term Hair Reduction-Hair growth cycle
Two factors play an important role in optimal long-term hair
reduction:
•
Hair growth cycle involves three phases: Anagen, Catagen, and
Telogen. Anagen is the growth phase, while Catagen and Telogen are
the resting phases. Permanent hair reduction can only occur during
the Anagen phase.
•
Skin types (according to the Fitzpatrick scale) are illustrated on the
diagram below: Darker skin contains more melanin, which competes
with the targeted hair for energy light absorbed into the skin, there is
a greater risk of adverse effects, and the epidermis may be damaged.
