Laser hair removal can be applied to individuals under the age of 18, but it usually requires long sessions and a more careful approach. Although there are no direct harms of laser hair removal in this age group, the procedure process may differ due to some factors:

1. Hormonal Changes
Hormonal changes during puberty can affect the structure and density of the hair. Laser hair removal is effective according to the thickness and growth cycle of the hair, but these hormonal changes may cause the laser to show its effect later or require more sessions.

2. Long-Lasting Sessions
The structure and density of hair in young people may be different than in adults. This may lead to longer laser hair removal sessions and more sessions. In other words, individuals under the age of 18 may spend more time to get the same result. More time may be required for the hair growth cycle to recover.

3. Skin Development
Since skin development continues, laser hair removal should be done more carefully in young people. However, this usually does not cause any harm during the procedure, only the process may be prolonged due to the change in skin structure.

In conclusion:
Although laser epilation does not cause harm in individuals under the age of 18, longer sessions and more procedures may be required. Therefore, it is important to get expert advice and correctly determine the expectations regarding the process before laser epilation is applied to young individuals.
