Help with hair!

Ok ladies. I'm in desperate need of help with my hair!! I'm having a very hard time with frizz issues. I'm assuming it's my job that's causing the issue because everywhere else it's fine. At work it looks like a rats nest lol. I usually never put anything in my hair. I never blow dry it. I just use shampoo every 3 days. Lately I've tried using leave in conditioner, oil, or anti frizz mouse. Nothing seems to be helping at all. I have long fine hair that's naturally straight. I just have no clue what to do lol. It's embarrassing because it seems like all of the other woman at work have no issues. It may be because I'm handling beanies all day. I work with embroidery machines. Please give me some ideas.
