Want to do a fun color but I don’t know if my hair can handle it?

I am at a point in my life and having a ton of shit happening where im like fuck it i want to dye my hair something fun. The only problem is that my aunt says my hair probably couldn’t handle it and she’s a hairstylist but I don’t know what she means but she won’t. So I probably will do it on my own but I want to know if she’s right and I shouldnt. I has it highlighted a couple months ago because I was working at a salon and I really really liked how it made me feel. Should I and how should I?
