Not all hairs grow at the same time – and only those in the active growth phase respond to the laser. Therefore, several sessions are necessary to permanently remove underarm hair.
However, the underarm area reacts particularly well: similar to laser treatment in the intimate area, 5 to 7 treatments are often enough for visible, long-lasting results. And this is due to the typical skin-hair structure: dark hair on light skin optimally absorbs the laser energy.
Depending on the hair structure, additional sessions may be required on other parts of the body, such as back hair removal or leg lasering. But even after the first few appointments, the hair growth will be finer and less. And the best thing is that you can shave as normal between treatments – unlike waxing or epilation, you don’t have to wait until the hair has grown back.
