How do I handle this situation?

I go walking everyday to a gas station by my house for exercise. I have been going there for like 2-3 years now and haven't really had any problems until lately. I have always been about having my hair and nails done. I like to braid my hair (add bundles), wear wigs, and do quick weaves bc my natural hair is about shoulder length and is taking forever to grow. There is this lady who is a cashier at the gas station and me and her never really talked but when I wore my natural hair for a while she all of a sudden was all talkative and friendly. I didn't really put to much thought into why that is , I just enjoyed having someone to converse with. As I am a stay at home mom and most of the day I just am home with my toddler. I dyed my hair red like a week ago and she completely stopped talking to me. I didn't really understand why. Now I put a wig on bc the color was kinda patchy and I didn't want to damage my hair any further. Now she is downright making fun of me and condescendingly asked me oh is that a wig. I feel a mix of emotions bc I genuinely enjoyed our conversation and the drastic changes confused me and hurt me tbh. She hasn't really said anything after that comment but it just rubs me the wrong way that she said that to me. I want to do or say something to guarantee she never does that crap again. But also don't want to be banned from the gas station bc other than her I like the gas station.
