"Hi, I'm Kelly. I'm a aesthetician and makeup artist at Ulta Salon and Cosmetics and I'm going to talk to you a little bit about what causes razor bumps. There's a few things. Basically a razor bump is an infection of the hair follicle that sometimes you can get like ingrown hairs. Now basically that can be caused from either dead skin dirt or debris being trapped within the follicle and then when the razor goes over it, it irritates, opens that follicle and you get a bacterial infection in there and that can cause either a razor bump or an ingrown hair and usually that's followed up by kind of puss like a pimple. Another thing that can cause shaving irritation is a dull razor that can cause either razor burn or irritation razor bumps. One of the easiest things to do to prevent that type of irritation is to exfoliate before you shave. This is going to help to remove any dead skin, dirt and debris, prevent it from going in to the follicle and prevent it from causing an infection, especially if you're prone to having that type of irritation and that type of infection, you want to make sure that you definitely do that first. And you can always follow up with a post-wax or post-shave treatment such as this one's a spray it helps to basically kill any bacteria and prevent it from infecting the follicle and prevent irritation. It also has a lot of calming and soothing botanicals to help calm any razor burn or anything like that. So those are a few of the things that cause razor bumps."
