If you are pursuing a degree/career in cosmetology, I highly recommend that you take a business course as well. A business course will help you understand how to effectively operate and manage your company. There is more to cosmetology than just learning how to cut someone’s hair. It is critically important that you learn how to manage and invest your money wisely, so that you are not always working for your money. Having fundamental business skills will allow your money to work for you.
