FDA does not allow for the marketing of technologies and services that state permanent hair removal. This is because technologies like laser hair removal provide a permanent reduction of hair growth up to 90%, give or take 10%. This means that you shouldn’t expect to permanently remove every single hair from the targeted area; however, you can expect to remove the vast majority of it. Hence, the FDA’s use of the term “permanent hair reduction” rather than permanent hair removal.

For most cases, the hair that grows in is usually lighter and finer. When you compare that 10% fine hair against waxing or tweezing, the reduction in hair is well accepted.

Why few sessions needed?

Did you know that your hair grows in stages? Laser treatments take so long to achieve permanent results because hair grows at different stages. Hair needs to be at the optimal growth stage in order to be effected by the lasers light. If the hair is in resting, shedding, or invisible stage, it will not be affected by the laser’s light and in turn will not be permanent

How Many Treatment Will I Need?
Due to the way laser hair removal works, few patients will see desired results after a single session. The only hairs that can be removed by this method are those that are in the active growth phase at the time of treatment. Hair enters that growth phase at different times, so multiple sessions will be required to finally address all the hair follicles in the treated area. For most patients, the average number of laser hair removal sessions is three to six, scheduled approximately four to six weeks apart. However, this number can vary based on certain patient factors.

Hair Color
Dark hair typically responds best to laser hair removal, especially hair with coarser texture.

Skin Type
Fair-skinned individuals typically require fewer laser hair removal sessions, while those with darker skin tones may need more.

Hormones
Hormones and other factors can have a direct impact on how quickly hair grows. When a patient has faster or slower hair growth than average, she may require a different number of sessions to achieve desired results sessions.
