This raises an affordable query: if the laser destroys the hair follicle, why does it take 4 to seven periods to do away with undesirable hair? The reply lies within the biology of how hair grows.
How Laser Hair Elimination Works
Laser hair removing targets the pigment (melanin) inside every hair follicle. When the laser’s vitality is absorbed by the melanin, it converts to warmth and damages the follicle’s capacity to provide new hair. Over time, the handled follicle can not maintain hair development.
Nonetheless, this course of solely works when the hair is actively linked to the follicle, which isn’t at all times the case. At any given second, the hairs in your physique are in several phases of their development cycle, and solely a few of them are in the appropriate lively section for laser therapy to be efficient.
The Three Phases of Hair Progress
Each hair in your physique cycles via three distinct phases: anagen, catagen, and telogen.
Anagen: The Lively Progress Part

The hair shaft comprises melanin and is linked to the blood provide that nourishes the follicle, so when the laser targets the hair, the warmth vitality travels down to wreck the follicle itself.
Solely about 20% to 30% of your hair is within the anagen section at any given time. The remainder of your hair follicles are taking a break.
Catagen: The Transition Part

Hair on this section is both loosely held in place or already falling out by itself. Laser therapy throughout telogen doesn’t successfully injury the follicle as a result of there is no such thing as a lively hair to conduct the vitality.
Why Timing and Consistency Matter
As a result of solely a fraction of your hair is within the anagen section throughout any single session, laser hair removing requires a number of therapies spaced strategically over time. Every session targets a brand new group of hairs which have entered their lively development section since your final appointment.
At Kalos Medical Spa, periods are sometimes scheduled 4 to 6 weeks aside, relying on the world handled. This timing is designed to catch as many follicles as potential throughout anagen whereas permitting your pores and skin to recuperate between therapies.
