The effectiveness of laser hair removal treatments can be significantly influenced by variability in hair growth cycles among individuals. Hair undergoes different phases of growth: anagen (active growth), catagen (transitional), and telogen (resting). Laser hair removal is most effective during the anagen phase because the hair is actively growing and more susceptible to being targeted by the laser. If a treatment is administered when the hair is in the catagen or telogen phase, the results may be less effective, as these hair follicles are not in the optimal phase for laser targeting.

Individual differences in hair growth cycles mean that treatment plans must be tailored to each patient, often requiring multiple sessions to effectively treat all hair in the desired area. This variability plays a crucial role in the overall success of the laser hair removal process, making it a key factor in treatment effectiveness.

While the choice of skincare products, shaving before the appointment, and even the type of clothing worn can have their own impacts on the treatment process, they do not directly affect the biological factor of hair growth cycles, which is fundamentally tied to the success of the treatment.
