Which of the following statements about laser hair removal is TRUE?

Laser hair removal typically requires multiple sessions for optimal results due to the hair growth cycle. Hair exists in three phases: anagen (growth), catagen (transitional), and telogen (resting). Lasers primarily target hairs in the anagen phase, and since not all hair follicles are in this phase at the same time, multiple treatments are necessary to ensure that the laser can effectively target as many hairs as possible during this growth phase.

The other statements do not accurately reflect the facts about laser hair removal. It does not guarantee 100% hair removal, as individual responses to treatment can vary widely. Consultation is a crucial step to assess skin type, hair type, and to determine the most appropriate treatment plan; therefore, it should not be bypassed. Lastly, while laser hair removal can be effective for many skin types, it is not universally effective for all, particularly for those with lighter hair or darker skin tones, where caution is necessary to avoid skin damage.
