How to style/maintain bi-racial hair?

Hello :D I am Black & Mexican, and even now at age 20 I still don’t know how to style my hair, or even take care of it properly :(

For context, my mom’s hair is straight & she is the one who raised me, so that’s probably why I’ve struggled so much…

I’ve mostly worn my hair in ponytails. I’ve never gotten my hair braided. & I usually wash/shampoo my hair every other day!

also, I was recently diagnosed with seborrheic dermatitis :( & i’ve lost hair, but it’s growing back rn & my symptoms are improving!!
