"How long should you wait between Laser Hair Removal treatments?"

Fundamentally, laser energy works to destroy hairs that are actively growing (in anagen growth phase). The growth phases vary for different regions of the body. Usually, I recommend treating the face every 4 to 5 weeks because hair growth phases cycle in and out more rapidly. For the underarms and bikini area, I usually recommend every 6 to 7 weeks, because growth cycles are slower. For best results, I also recommend that you try to have consecutive treatments at... more

Allow enough time between laser hair removal treatments for adequate hair re-growth

You need to space your treatments to allow enough time for ample re-growth.

Optimal long-term benefits depend on the area you wish to have treated, the hair density, and your hair’s growth cycle. ... more

How Much Time Is Allowed To Lapse Between Each Hair Laser Treatment?

The time between each treatment is chosen arbitrary. Since laser or IPL works on actively growing hair follicle, the next treatment is for the new growth whenever that happens.

Wait Time not a Problem

You will not jeopardize the results of your treatments by waiting longer between appointments. You should continue to shave between treatments and resume them when you get back.

Laser hair removal sessions can vary with different intervals between sessions

Many people are not able to commit to an every four or six week interval in between laser hair removal treatments. Trying to match the treatment with the growing phase of the hair cycle is possibly more academic than clinically required to obtain a satisfactory result in reduction of hair growth. If you have had several sessions and can not return for a few months, you can continue on your return.
