Laser hair removal works by heating the hair follicles to stop new hairs from growing. This puts the hair follicles in a state of dormancy for a long period of time — much longer than with shaving and waxing. When the hairs do grow back, they’ll be lighter, finer, and fewer in number.
Although the procedure is often touted as a form of “permanent” hair removal, laser treatment only reduces the number of unwanted hairs in a given area. It doesn’t get rid of unwanted hairs completely.
The laser can react with hair on the skin’s surface which will cause some irritation and maybe dreaded burnt hair smell which I learned first hand, yay. Thankfully for me, I knew that whole ‘shaving = thicker darker hair’ was a really common beauty myth.
Hair follows a unique growth cycle that involves resting, shedding, and growing periods. Recently removed hair that is in a resting phase will not be visible to the technician or laser, so a person may need to wait until it regrows before removing it.
For most people, laser hair removal requires several treatments over the course of 2 to 3 months.
