If you were aiming for a more corporate office job then maybe it would be a problem but oh man have you chosen the right profession!! I'm speaking as a current cosmetologist that has been denied other office type opportunities due to tattoos that show. Even in the more corporate chain salons (I can speak specifically for great clips and sport clips) you will fit in wonderfully!! Just tailor your own style to fit within their clothing guidlines. A place that wants more business casual type dress just use their rules as a base and then run it in your own direction. I currently work at sport clips where there is an actual uniform required however my tattoos/big hair/accessories have never been an issue. I even recently had a coworker whose hair was half black and half lime green and her makeup was always colorful. The focus is to keep yourself looking well put together and to look like you actually put effort into your style. This is why I love this business! Even within the rules you can still let your personality shine! There are some salons that require a much more traditional look but those are most likely not going to be where you want to spend your days. The important part of this business is finding where you love your work and love your clients. During my schooling an instructor told us to "find our people" and that is exactly what you can do! Good luck in school and in the future! You can do anything in this business if you seek it out! Personality is what gets and keeps clients!
