To understand how laser hair removal works, you must understand the cycles of hair growth. Hair grows in stages — anagen, catagen, and telogen. Anagen is the growth phase when the hair is connected to the follicle, and telogen is the rating phase when the hair is pushed out of the shaft. Different hairs on the human body go through different stages at different times.
During laser hair removal, the laser device delivers laser energy into the unwanted hair follicles. The pigment in the hair absorbs the energy, and the associated follicle is destroyed. However, laser hair removal only works on the hair growth in the anagen stage. If the follicle is dormant, i.e., in the catagen or anagen stage, it won’t be affected by laser hair removal.
As such, each laser hair removal session only stops partial hair growth. Each session destroys the hair follicles currently in the anagen stage. That’s why you need multiple sessions of laser hair removal in Covington and Mandeville, spaced about four weeks apart to target all the unwanted hair follicles. Furthermore, you may also need occasional touch-ups after the final session if a follicle is left untouched.
