The proliferative phase is the most vital stage during which the hair follicle is actively growing. At this stage the follicle is securely rooted into the hair bulb, and receives nourishment from the blood supply that sustains cellular activity.

Crucially when the hair contains the most concentrated pigment, the natural pigment responsible for hair color. Laser-based depilation relies entirely on absorbing the pigment.

The laser device releases a precise wavelength energy that preferentially targets the pigment granules in the hair shaft. Following energy capture, the photonic energy change into focused warmth, which induces controlled thermal destruction to the follicle, sufficient to inhibit or delay future hair growth.

As only hair shafts in the growth stage have sufficient chromophore and are vascularized by the dermal papilla, лазерная эпиляция на все тело they are the only ones that can effectively absorb the laser energy. As a result, at every appointment, the device can only deactivate a fraction all visible follicles.

Hairs in the catagen or telogen phases are disconnected from the dermal papilla and lack enough melanin, causing them to be invisible to the laser.

This natural cycle explains why multiple sessions are essential to capture each follicle as they transition through the anagen phase.

Strategic scheduling and long-term commitment are the cornerstone to attain sustained hair suppression.

Understanding the anagen phase equips both practitioners patients to establish clear goals and optimize protocols that respect the follicular cycle.
