Some things are better in slow motion — and laser hair removal is definitely one of those things.

A video from Veritasium shows what it looks like when hair is exposed to a laser.

Dark hair contains melanin, a pigment that protects us from ultraviolet light. Bursts of a high-energy laser are absorbed by the hairs more than the skin, and the hairs increase in temperature as they are exposed to the laser.

What that  means is it makes the hair explode like popcorn.

That happens when moisture evaporates from inside the hair follicle (scroll to 2:01 for the best example).

Eventually, the follicle is damaged to the point where cellular bonds break down during “denaturation.” When enough damage is caused, the hair will not grow back.

Lasers can remove hair permanently or for several months, as the results differ for each person.

And what that means is we’ll keep getting these videos.
