Husband family insulting me

I’ve been with my now husband for over 4 years and me and I’m his mother has always had a bad & rocky relationship. Well after we got married this year she started to change & I genuinely thought that she started to care about me. Well this morning, me and my husband goes to visit her & she made us breakfast which was very nice. After awhile she started to talk about why do I wear wigs and weaves and the that I need to not wear those and wear my natural hair. She said I don’t need to be wearing them next time I come over and that I’m too stuck on my appearance. Which is not true because I don’t even wear makeup. The truth is that I have alopecia and so I can’t grow out my natural hair as easy and everybody else can. I’ve felt subconscious about it for years but I’ve just learned to just accept it and wear wigs. Well she was sayin this while my husband was sitting at the table. And so I made a comment to my husband saying that he’ll love me regardless of how my hair is and he made a face and everybody (mom, sister & him) laughed at me. It made me feel so bad but I just laughed it off because I’m it good at all in awkward situations. So she kept going on and on about my hair then I got uncomfortable and my husband made a joke like “ok let’s leave before you snatch my wife wig off” I was annoyed of the comment but I just got up and walked towards the door and started to tell everybody good bye. As I was leaving. My husband was just standing there not saying anything and his mom said in the rude ant tone” if I see you with they wig on again. I’m going to snatch it right off your head” at this point I was UPSET & before I could say anything rude or vial. I left the house and my husband was STILL standing next to his mom and sister and I had to tell him, “let’s go!” In a stern voice. When we got to the car. I was upset and saying that his mom went too far with that comment and why didn’t he back me up or say anything. Instead of him understanding me being upset he stated to yell at me saying that he doesn’t know what I was talking about and that he thought everything was cool and ok because I was laughing most of the time (nervous laugh) he was mad at me and turned it around on me now idk how to feel anymore.. am I wrong for being upset?
