HI. It appears you went to the wrong salon professional. You can opt to wait a bit longer so that you have some wiggle room when you go to get a cut. However, you're growing it out from a "crew cut" situation and so your hair will be round until you get it properly cut and shaped.
You probably should find a hairstylist who can help you style your hair using the right products and tools. You are most likely using the wrong brush, tools, and/or not using the right technique to style your hair.
Go to YouTube and look up how to style your hair. Many professional brands have how-to videos such as those to market the product of course, but they have great ways to show how to properly style the hair.
Also, when you decide to find a salon professional, do your research and go by quality, not by price.
Best of luck.
