How many sessions are needed for laser hair removal treatment in case of leg done by ND - Yag laser?

Thank you for your
question in regards to a Yag laser. Laser hair removal is a hair reduction treatment. Six treatments are usually recommended to begin the process. Depending on the location and type of hair you have will determine the necessary amount of treatments needed, following touch up treatments as well. After a series of these treatments, you will begin to notice the hair in the treated areas doesn't grow back or is thinner, finer and much less dense. To be sure, see two
or more board-certified providers in your area for a complete evaluation to
make sure you are a good candidate and that it is safe for you to have
treatment. I hope this helps.

There are a few different lasers that can be used to reduce hair growth.  None of them can claim 100%, but can be extremely effective.  6-8 treatments is pretty standard practice, more may be needed depending on your rotating growth cycles.  In some cases, it is also normal to have semiannual maintenance treatments.  Different lasers are attracted to different targets such as the pigmentation of the hair.  Finer hair can be a smaller target, but can still respond to treatment
