For instance, my mother cut all my hair off when I already had low self esteem. I looked like a ugly little boy, in my opinion. Her explanation was that I refused to sit still- unlike my sister. This is because her dragging a brush through my hair and hitting the tangles was EXCRUCIATING for me, while it was mildly uncomfortable for my sister..
Circe47, the same thing happened to me. I was a weird, overweight little kid, and my mom gave me a buzz cut, and said it was my own fault for crying when she brushed my hair. I felt like I looked like a monster. To this day, I get the willies anytime someone touches my hair. It's made things quite difficult in relationships and can be a full trigger sometimes depending on the situation.
