This depends heavily on the individual program you attend. A barbering program will likely take a bit of time as it’s a trade program similar to cosmetology. However, the specifics of the length of time will depend on the program you attend. It will also depend on whether you go full-time or part-time; as you might expect, a part-time program will take longer than a full-time program but will require less of your time while you go through it, making it ideal for those who need to continue to work while in barbering school.
