If I shave between my Candela Gentle Yag laser treatment, will it be effective? Can my hair be long during treatment? (Photo)

Yesterday i had my 6 session of laser on my legs, I waited like 2 and a half months since session number 5 because i was constantly receiving sun and shaving my legs.. My hairs were long but i did it anyway, because I'm starting to think that everytime that i shave my legs, more hair grows and i dont know if i might be losing the treatment. Right now I have burned hairs (as usual) but I also see hairs that seem to be intact, and i know if the laser didn't get to them for the long they were.

Thank you for your question. It is okay to shave between laser hair removal treatments. However, shaving does not cause more hair growth with laser treatment. It is recommended to shave before laser hair removal to decrease the risk of burns and pigmentation. It is not recommend to wax or pluck the hair as this removes the hair follicle the laser targets. I recommend discussing your concerns with your treating physician. Best of Luck!

Laser hair removal and shaving

Shaving does not cause more hair growth with laser treatment (or any other time).  I require my patients to shave prior to their laser hair removal to decrease the risk of burn and pigmentation as cited in another answer in this thread.

You do need to avoid the sun when having laser hair removal.  You can safely shave the hair in between the laser treatments and just before treatment.

Laser Hair Removal and Shaving

For laser hair removal to be effective, hair needs to be intact in the follicle, but should be short and shaved for two reasons: First because if the hair is long, the long portion of the hair will absorb some of the laser's energy as opposed to all the energy being directed to the hair bulb itself, making the treatment less effective. Second, since some of the laser's energy will be directed to the hair laying on top of your skin, you risk receiving burns and unwanted pigmentation. In our office, we would not require you to shave your legs because we will shave them prior to treatment so that all of the energy can be focused on the bulb, the growth center of the hair so that the treatment is maximally effective.
