What is laser hair removal application?
Laser hair removal application is a hair removal operation with a device that emits ultraviolet rays. In fact, before learning more about laser hair removal, it is beneficial to learn about basic hair growth cycles. All hair on our body completes their growth in 4 stages which are pre-anagen, anagen, catagen and telogen. Pre-anagen phase is the period where hair roots start hair growth. Anagen phase is the most active development of this hair and hair grows under the skin. Anagen phase is the most suitable phase for laser hair removal. Catagen phase is when activity of live cells inside the root stop, root structure changes and transition to interlude. Telogen phase is when hair growth stops and hair are discarded from body.
Laser hair removal application that consists of multiple sessions is a medical process applied to end hair growth by damaging hair roots in anagen phase in controlled manner with ultraviolet rays. Main reason for multiple sessions in laser hair removal is because each hair root is in different anagen phase. Since each root has different anagen phase, it is not possible to stop root activities in one session.
Are laser hair removal results permanent?
Purpose of laser hair removal is to damage hair roots in controlled and permanent way without damaging surrounding tissues. If there are no hormonal problems, when a device that is suitable for hair and skin colour of the individual is used, hair growth can permanently be stopped. With current technology and new devices, laser hair removal can permanently end hair root activity. Hair in laser hair removal region can decrease up to 90%.

Since laser hair removal rays are effective on active hair roots, maximum results cannot be achieved in single session. Because not all the hair roots are active in the same period. While hair roots are active during application are impacted by laser hair removal, there will be no effect on roots in other phases. Since hair colour, structure and growth phases change for each individual, number of sessions depends on each individual. Generally, at least 8 sessions are recommended for successful results. Additionally, different number of sessions for different regions is another important parameter.
While interval between each session can be 6-8 weeks for body, this interval is 4-6 weeks for face. These intervals may be longer after couple of sessions. Ideal time for the next session is when hair grows back and hair is noticeable from skin. Such growth shows that hair roots are active and hair roots can be removes with session.
