Understanding the Anagen Phase and Laser Targeting > 자유게시판

The proliferative phase is the critical period during which a pilosebaceous unit is in its growth cycle. During this phase the follicle is securely rooted into the hair bulb, and remains linked the vascular network that fuels its growth.

Simultaneously when pigment concentration is highest the greatest amount of melanin, the natural pigment that determines its pigmentation. Laser-based depilation is fundamentally based on targeting this melanin.

The targeted light source emits a specific light spectrum energy that preferentially targets the melanin within the follicle structure. Upon uptake, the photonic energy transform into thermal energy, that induces controlled thermal destruction to the follicle, capable of stall or postpone future hair growth.

Because only hair shafts in the growth stage have sufficient chromophore and remain attached to the blood supply, these are the sole targets that can efficiently capture the photothermal effect. Therefore, in each treatment, the laser can only target a portion of the total hairs.

Hairs in the catagen or telogen phases are not connected to the blood supply and do not contain enough melanin, эпиляция ног выше колена rendering them undetectable by the energy.

This natural cycle accounts for why multiple sessions are essential to capture all the hairs as they cycle the target window.

Precision timing and consistency are non-negotiable to attain long-term, lasting results.

Grasping hair growth cycles enables both clinicians and clients to set realistic expectations and design protocols that align with biological timing.
