Hairdressing is an entirely unregulated profession in the UK, which means that anyone can set up shop as a hairdresser. Unfortunately, since hairstyling can involve the use of complex chemicals, especially when coloring, straightening, or perming hair, this can be a recipe for disaster, some hairdressers are voluntarily registered as “state registered hairdressers,” which means that they subscribe to a code of conduct. Choosing one of these salons would be a safe choice.
