Sorry about the delay. The primary thing that they want to see is significant ties to the UK or to Poland. They want to make sure that you will go back. Not that you will decide to stay in the U.S. and hope for a better life. If you were married and your spouse was staying behind or your spouse had a great life in the UK that he would not easily abandon, then all of those things would go in your favor. If you had your own successful business (not just a start-up with not much money invested as you do now), and that business needed you in the UK to continue to be successful, then that would be something else in your favor. If you were close to finishing your degree, you probably would want to finish in the UK so you wouldn't stay in the U.S. But starting at a beauty school, something that you might easily be able to pick up in the U.S., that wouldn't be very convincing as a tie, I'm afraid. You can apply again if you like, but they usually like to see 6 or more months between applications (maybe why they didn't want to see anything that you had). If you cannot wait that long, and they still don't want to review what you have with you, you can ask to speak to a supervisor and hopefully they will be more amenable to reviewing your full file. But I have to tell you that it will not be easy. B-2 visas are not easy to get for young people that do not have many strong ties outside of the U.S.
I will provide you with two links that may be helpful. The first is to an article that will explain what they look for when issuing a non-immigrant visa like the B-2. The second is a list of things that can be presented to prove non-immigrant intent and the strong ties to the home country:
Hopefully these things will be helpful. You should try to wait awhile before applying again and try to develop more things that would convince them that you will go home when the time comes.
