IPL – SHR

Hair grows from deep within hair follicles, which are thin cavities embedded in the dermis. Hair does not grow continuously, but grows in a three-phase cycle. The anagen, catagen, and telogen phase. Hair follicles that are in the anagen, or active growth phase, have the largest amount of melanin, or pigment, and can absorb light energy from the treatment head. Only 30% of the follikels are in the anagen or active growth fase. This is why you need more treadments to hit all of them in this phase.

The hair follicles that are in catagen or telogen growth phases are less pigmented. Therefore, these follicles do not absorb light energy as well and hair growth is not impaired.

The energy, or heat, from the treatment head damages the hair follicle, which impairs its ability to grow hair. With time, the hairs that were present in the damaged follicles will fall out, resulting in a smoother appearance and less hair growth.
