Laser Hair Removal has no age requirement therefore it can be done at 13. Usually we have patients younger than 18 see their regular doctor to make sure that there are no medical or hormonal issues. Although you are allowed to have the procedure done, you must be accompanied by a legal guardian for each appointment because you are a minor. Usually we advise patients to start with a small test area to ensure you are comfortable with the procedure and that the results are good.
