How Much Hair Should Fall Out After Session of Laser Hair Removal (Bikini)?

The amount of hair that falls out at each session of laser hair removal can vary. Hairs grow in 3 different phases, and laser hair removal is effective against hairs in the growing phase. If the hairs are in the correct phase, they should be permanently reduced. Some hairs can be ejected from the follicle immediately, while some can continue to grow and fall out over the next few weeks. We usually recommend neck and face treatments to be done every 4 weeks and any body area below the neck every 6 weeks so that the hairs will hopefully be in the correct phase for laser hair reduction. Some treatments will yield a lot of hair removal while others will result in very little hair removal. It just depends on the phase of growth.

The amount of improvement will vary. I typically have patients do every 4 weeks for the first 3 times and then every 4-6 weeks for 3 times after. It will take a series of treatments and some people need treatments to maintain. See an expert in laser hair removal for best results. Best, Dr. Emer

The industry standard recommends 6 treatments performed over 1 1/2 to 2 years. However with each treatment the hairs will fall out within 2 to 4 weeks and you will be hair free until the inactive hair growth comes in. Eventually most of the hair will develope into Anagen hair cycle for a permanent hair reduction.

Ideally, every hair in the growth phase will fall out or shed after a laser hair treatment.  Since not all hair is in the growth phase, only a portion of the hair can be removed during each session.  Each treatment should either have less hair or finer hair from previous treatments.  

You should see at least 20% of the hair fall out after each session. If you only had a few hairs and your session was short I’m assuming that your treatment wasn’t done properly or the laser wasn’t set at the right parameters. The hair on the bikini area is usually dark and thick so it should work faster and better. You still need to do at least six sessions for the best results, but you should notice a big improvement after each treatment.
