Regarding hair cycles, which statement is accurate?

The effectiveness of laser hair removal is significantly influenced by the hair growth cycles, which include phases such as anagen (growth), catagen (transitional), and telogen (resting). During the anagen phase, hair is most actively growing and is in the most suitable stage for laser treatments because the hair follicle is fully intact and responsive to the energy delivered by the laser.

Treatments aim to target hair in the anagen phase, which means that for optimal results, multiple sessions are necessary to catch all hair in this phase since not all hair follicles grow at the same time. Consequently, understanding the hair growth cycles allows for more strategic planning of treatment sessions, maximizing the likelihood of effective hair reduction.

This principle highlights why statement C accurately reflects how hair growth cycles affect the overall effectiveness of laser hair removal treatments. Other statements either misunderstand the process of hair growth or misrepresent the methodology required for effective treatment.
