Ask the Expert: How often can you do IPL/at home laser hair removal?
BY SAMANTHA WELCH, ESTHETICIAN
Treatment Plan & Frequency for At-Home Laser Hair Removal
There are always two phases to any laser hair removal treatment:
- Start-up Phase: Consists of weekly or bi-weekly treatments for the first 4-12 weeks, depending on your device. The goal is to disrupt the hair cycle by targeting your roots repeatedly during their anagen or growth phase. Once done, your hair will be thinner and sparser, and its growth indefinitely delayed.
It’s best to use the highest intensity you can for better results.
- Maintenance Phase: Once your normal hair growth has been stunted, your treatments can be monthly or as-needed. If hairs start to grow back, treating them will once again make them dormant.
Different Devices with Different Instructions
We've reviewed over 35 at-home laser hair removal devices over the years. The average recommendation for the start-up phase is on a weekly basis.
Doing treatments more than once a week won't expedite results, even with the best-rated IPL hair removal devices.
Your hair will still go through the hair cycle (see below) after your treatments and this takes 1-2 weeks minimum.
Weekly is also as fast as you can go on most devices with minimal risk and without wasting your flashes on already dead hair.
However, you should still defer to your device’s user manual for the ideal home IPL treatment schedule.
Exceptions to the Rule
There are one or two devices that are exceptions to this rule, depending on technology used.
One is the JOVS Venus Pro which recommends 3x a week treatments in the start-up phase.

On the opposite end, devices like Silk'n Infinity that specialize in dark skin recommends one session every two weeks as a jumping pad.
The Silk'n Infinity recommends sessions once every two weeks to start.
Whichever device you decide to get, it’s much more important to keep a consistent, strict schedule to be able to see results.
You want to gradually damage your roots until it’s no longer able to grow hair at a normal pace.
You can delay re-growth anywhere from weeks to months and years.
But you have to remember that hair is very resilient.
Front-loading your treatments and then falling behind schedule can allow your follicle to recover and revert back to growing healthy hair.
You need to consistent treatments until you see your hairs get finer and sparser, before moving on to monthly or as-needed maintenance.
What You Should Know:
The Hair Cycle & Permanent Hair Removal
- Hair growth comes in cycles and in different durations based on the body part. This cycle takes anywhere between several weeks to months.
- The goal of every laser hair removal session is to delay this cycle significantly for months to years by slowly damaging your roots.
- Laser hair removal treatments are only effective on hair that’s in the ANAGEN phase. Once you’ve treated a hair follicle in the ANAGEN phase, it will accelerate the hair cycle until the strand dies and falls off on its own.
- This process cannot be hurried by doing IPL more than once a week. Weekly sessions are the fastest that you should re-schedule treatments.
- Doing IPL every day, every other day, and even twice a week runs the risk of damaging your skin or your eyes. You’ll also be wasting your device’s limited flashes.
