Is laser hair removal safe? Here’s all you need to know

According to certified dermatologist Hadley King, MD, laser hair removal treatments emit light of a wavelength that is absorbed by melanin and the hairline. “This light energy is converted into heat, which permanently damages and destroys hair follicles,” she says.

Winnie Moses, MD, a certified doctor of medical aesthetics and founder of Parfaire Medical Aesthetics in Los Angeles, says laser hair removal targets hairs that are in their actively growing phase. Once the treatment is finished, these hair follicles are destroyed and will not grow back in the next cycle. But because hair grows in three phases, anagen, catagen, and telogen, not all follicles are at the same stage at the same time. You will therefore need several laser treatments to optimize the results. “That’s why the hair removal process is usually done in five to six sessions, one month apart,” says Moses.

We should also note that this professional hair removal service can be quite expensive (and not to mention time consuming) – so it’s not a realistic option for everyone. Many people find it useful, but it is by no means the only way to get rid of unwanted hair; we will offer you some alternative hair removal methods below.
