Advantages and Disadvantages

There are several disadvantages to many of these hair removal methods. Most are not permanent, can cause medical problems and permanent damage, or have very high costs. Some of these methods are still in the testing phase and their methods have not been clinically proven. One should seek the advice of a doctor-supervised facility when choosing these hair removal methods.

One issue, that can be considered an advantage or a disadvantage depending upon an individual's viewpoint, is that removing hair has the effect of removing information about the individual's hair growth patterns due to genetic predisposition, illness, androgen levels (such as from pubertal hormonal imbalances or drug side effects), and/or gender status.
