While there is no definitive age restriction for laser hair removal, there are some considerations to remember. For instance, teenagers undergoing significant hormone changes may also experience increased hair production. However, it is usually more effective to wait until after age 18 to get hair removal because the results are more consistent and long-lasting without the concern of hormonal influence. It is also important to remember that laser hair removal is ineffective on gray hair, so that may be another age consideration to remember.
