Laser Hair Removal & Covid-19 Pandemic

In light of the current situation (COVID-19) and following the guidelines imposed by the authorities, cosmetic clinics were obliged to close and many of the planned treatments were interrupted. The following information is presented to answer some entailed questions regarding the interrupted laser treatments.
In order to know how Laser hair removal works, we need to understand how hair grows. Hair grows from deep within hair follicles, which are thin cavities embedded in the inner part of the skin (Dermis). Hair does not grow continuously but grows in a three-phase cycle.

Each growth cycle includes an Anagen, Catagen, and Telogen phase. During the Anagen phase, the hair grows actively from the follicle. The next phase of the growth cycle is the Catagen phase. This is a short transitional
period in which the hair stops growing and the hair follicle shrinks in size. The follicle breaks away from the dermal papilla, which supplies nutrients to the hair follicle. The last phase of the growth cycle is the Telogen,
or resting phase. During the Telogen phase, the hair follicle attaches to the dermal papilla, at which point the follicle re-enters the Anagen phase. As a new hair begins to grow, the old hair is pushed out of the follicle.

Now let us see how the laser works in the process of hair removal?
During the procedure, the specialist will guide the laser over the treatment area. As the laser pulses have emitted, it delivers light energy, which travels through the skin and is absorbed by the hair follicles. Those hair follicles that absorb energy, or heat, from the laser, will be damaged. Hair follicles that are in the Anagen, or active growth phase, absorb and respond the best to the laser treatments. As not all hairs are actively growing at the same time, a single procedure will not treat all of the hair follicles in the area. As the follicles in the transitional and resting periods return to the active growth phase, you may notice some hair regrowth but not as thick as it was before the treatment. This regrowth will become thinner and lighter with each subsequent treatment until there is little, to no hair at all. This is the reason it typically takes multiple treatments to achieve the best results.
