How do y’all deal with a overbearing MIL when it comes to your kids?

Long story short, she’s so overbearing and gets mad when she can’t have her way with my kids. There’s a language barrier so we don’t talk.

She keeps putting my daughters (1) hair in rubber bands and the grease that makes her hair too greasy. I told my husband to tell her not to do it because 1) it makes her hair greasy and 2) she rips the rubber bands out and damages her hair

Of course husband gets mad because his mom doesn’t do anything wrong. I’ve told him numerous times and my daughter still has rubber bands and greasy hair when she gets back home

I’m tired of her acting like she’s my kids’ mom. She even baby wears my 1 year old when I’m not around and kisses them
