Ok so im 15 years old and I have hair that about to my shoulders. Its so big and unruly and it get matts in it even if i brush it well, but i can RARELY brush it. Im white (very pale haha) and my hair is 3a probly. But I really need some help... people make fun of me at school, even my friends :/ I just want it to stop, and I refuse to straighten my hair. Any products, cuts, tips for me? And the attachment is of me

but my hair was up so its not as curly.
