In the weeks leading up to your laser hair removal procedure, you will be advised to adhere to certain guidelines. To begin, you’ll want to avoid tweezing and waxing your hair for at least six weeks prior to your procedure. For the treatment to be effective, the roots of the hair need to be intact so the laser can effectively target and destroy them. In addition, you’ll want to avoid excessive sun exposure six weeks before and after your treatment to ensure an optimal result.
