What is Laser Hair Removal and How Does It Work?
Laser hair removal is a procedure based on the principle of selective photothermolysis, where intensive light energy at specific wavelengths is absorbed by the melanin pigment in the hair root and converted into heat in a controlled manner. The aim is to weaken the growth capacity of the hair follicle without harming the surrounding tissue and to achieve a long-term reduction in hair density.
Scientific Mechanism and Growth Phases
Hairs exist in the body in three different phases: Anagen (active growth), Catagen (regression), and Telogen (resting). Laser energy shows the highest effect on hairs in the active growth (anagen) phase, which is rich in melanin. Since not all hairs in the body are in this phase at the same time, laser hair removal cannot be completed in a single session; sessions are repeated at specific intervals in accordance with the hair growth cycle.
Factors Evaluated in the Pre-Assessment
- Skin Phototype: Energy and wavelength parameters are determined according to the skin tone.
- Hair Color and Thickness: Dark and thick hairs absorb light better thanks to melanin density; the effect of the laser is limited on fine, blonde, or white hairs.
- Hormonal Status: Underlying conditions must be taken into account in areas with high hormonal sensitivity such as the face, chin, neck, and abdomen.
- Medications and Skin Sensitivity: Medications that cause sensitivity to light (photosensitivity) or active skin conditions are evaluated.
Pre- and Post-Procedure Care
Procedures that pull hairs out from the root, such as waxing, tweezing, or epilators, should not be done prior to the application; hairs should only be shortened with a razor or trimmer as recommended by the practitioner. Laser is not applied to tanned or sunburnt skin.
For the first 24 hours after the procedure, hot water, saunas, intense exercise, and irritating peeling products should be avoided. The skin must be protected from UV rays using sunscreen creams recommended by the practitioner.
