high school with curly hair

the constant comments on my hair is killing me. i can't go a day without someone asking me "did you even brush your hair this morning?" NO 😭 i get backhanded compliments "your hair would be really pretty if you took care of it!!" they say so much worst and i'm so done. my father who is literally bald won't stop with the comments either he tells me straight up it looks horrible, i have people asking me to straighten my hair constantly, the only thing i ever get for birthdays and christmas is hairbrushes and conditioner. its my biggest insecurity and im trying so hard to figure it out. i think curly hair is so beautiful and i really wish my hair would cooperate. no one in my family has even close to my hair type so ive been figuring it out myself my entire life. i'm on the verge of blowing my savings on Brazilian blowouts
