HELP- rec letters and purple hair?!

Hi y'all!

So, I'm new on this website, but I plan on attending UF in the fall as a freshman and want to rush, however I'm a first generation college student and really know nothing about the process. After doing some research, I've discovered that letters of recommendation seem to be fairly important, especially here in the south. My problem is that I don't know ANYONE who has been in a sorority, and therefore won't have even one. So basically, do you think that this will completely kill my chances during recruitment?

Also, I had planned on dying my hair lavender in about a month (I've had this kind of hair before, but it's completely faded and I'm back to blonde), should I refrain from doing this? Will the sororities look down on me for it?

Thank you guys so much!!
