Have you ever been to a barber and noticed they didn't even attempt to clean the machines while you were sitting in their chair? This is the risk that you take when you consistently go-between different barbers every time that you need your hair cut. Barber-Hopping is common practice amongst clients but it's also dangerous and risky and you can be exposed to bacteria that can cause pseudofolliculitis. In its advance level, pseudofolliculitis causes the skin to form keloids in clusters on the back of your head or around the facial area. But you don't have to worry because this can be treated and permanently cured. I've always been an advocate of good hygiene which is why I wear and change gloves between every cut. You shouldn't be afraid to ask your barber to clean his equipment before cutting your hair. You're not insulting him/her, you're just looking out for your well-being. Another factor that plays into what separates good barbershop from a really good barbershop is the environment. A shop can look clean on the surface may not necessarily be as clean as you think. Barbercide; a primary cleaning agent for most stations isn't something that is always used or changed regularly. In a place where you're at risk of cross-contamination, hygiene shop be number 1 on any list. Unfortunately, this isn't the case and customers are finding themselves developing conditions that wasn't included in their service.
