Why do you believe females make up for 85% of self-injurers?

Sky (She/they) 💖 • ❤ Intersectional Feminist ❤ Queer ❤ Genderfluid

Inspired by intro to sociology class and textbook, what do you think contributes to this? In my textbook, it says that feminist researchers believe the reason behind it is because females are pushed by society to attend to their bodies by hair removal, skin treatments, and depigmentation. Do you believe this or do you have another theory?
