I'm a cosmetologist!
I'll be licensed in a few months. It's one of the most rewarding careers out there.
You don't HAVE to have nice nails, hair, and makeup...But I'm going to be honest, your clientele will appreciate it. Would you go to someone to get your nails/hair/makeup done when they look like they don't even know how or what to do? You'll learn in school that your appearance attracts clients. If you look unprofessional, your clients will be unprofessional(meaning they will not take you seriously.) If you want money, you MUST be a successful cosmetologist...there are too many of us out there, you need to create an image for yourself.
If you need any help/advice, PM me and I'll be glad to give you help!
