Laser Hair Removal

The most common question we hear at Rani Beauty Clinic is: how many sessions will I need? The short answer is 6-8 sessions for most body areas, but several factors influence this number.

Hair grows in three phases: anagen (active growth), catagen (transition), and telogen (resting). Laser is only effective during the anagen phase when hair is connected to the follicle. Since only 20-30% of hairs are in anagen at any given time, multiple sessions are needed to catch all follicles during their active phase.

Treatment area matters significantly. Underarms and bikini areas often respond quickly, showing major reduction after 3-4 sessions. Legs, arms, and larger areas typically require the full 6-8 sessions due to longer growth cycles. Hormonal areas like the chin and upper lip may need additional maintenance due to ongoing hormonal stimulation.

At Rani Beauty Clinic, sessions are spaced 4-8 weeks apart depending on the body area and its hair growth cycle. We monitor your progress at each visit and adjust settings as hair becomes finer. Most patients achieve 70-90% permanent reduction by the end of their series.

Common Questions

Some patients see significant reduction after 3-4 sessions, especially on responsive areas like underarms. However, completing the full series ensures you target all follicles through their growth cycles for maximum permanent reduction.

Spacing allows different hair follicles to enter the active growth phase. The laser only works on growing hairs, so spreading sessions over several months catches more follicles in their vulnerable stage.

You will have some reduction from completed sessions, but results will be incomplete. Finishing the full series is important for targeting all follicle growth cycles and achieving lasting smooth skin.
