Polite way to follow-up Wedding Hair

So I need options on how to phrase a follow-up message to my FOH sons girlfriend who offered to do my hair and make-up for the wedding. We did the trial and I didn't like the make-up so I sent her a message stating that I was gifted my make-up from a former classmate (esthetic school). I stated in the message I would still love for her to do my hair and help me cover one of my tattoos. Well she never responded. Now the wedding is 41 days away and I don't know what to think. She wasn't going to charge me or anything as she isn't a true hair professional (went to cosmology school only). I just need help with how to phrase the follow-up message without sounding rude but also want to give her an easy out. However, I also need to know now if she is going to do it so I can find someone else. Any advice on how to phrase it is appreciated!
