Parents / step parents please comb/ brush the child’s hair

I just had to get some other options on this topic. I have a 6 year old daughter. Her dad and I are not together. He’s remarried. But I’m the full time custodial parent. Everyone that knows me know that I always comb my daughter’s hair whether we’re going somewhere or not! She’s a reflection of me/ him and I ! When my daughter go to stay with her dad. They don’t comb her hair for a day or two. Sometimes three days. Then when they do comb her hair it still doesn’t look as if it’s been combed. My daughter has naturally curly hair but I still use products in her hair like.. mixed kids curly gel.. or long aide curl activator gel.. Her stepmom has allergies and doesn’t like or use anything with fragrance because it bothers her. Therefore her stepmom and my daughter’s dad doesn’t use the items I’ve sent for my daughter’s hair or for her bath. Her dad stated in his opinion I use to much fragrance on her. I’ve asked them to use the items that I send but her stepmom says she’ll use what she (stepmom) already have she (stepmom ) stated she use natural products. I’m already annoyed because they don’t use the products that I send for her hair! I understand and get the part of the stepmom having allergies. But they don’t comb her hair for days even with the natural products. Her dad says they’re just lounging around and aren’t going anywhere therefore she doesn’t need her hair combed. But every time my daughter FaceTime me or they take pictures of her ..my daughter always looks as if her hair hasn’t been combed for days! Don’t get me wrong because her dad and stepmom are great parents. They’re loving, caring, good providers, and very active in my daughter’s life. I guess the question that I’m wanting to know is.. Am I over reacting about my daughter’s hair not being combed?
