Curly girls ??? Help a sis out

Let me first of all give u a backstory on my hair.

Im ethnically asian (full vietnamese) so practically almost all my family members have pinstraight hair, including my lil sis. I also used to have straight hair as a child.

I know hair can change overtime, and a few years ago my hair was a big POOF ball of frizz and just a hecka lot of volume, to the point where i would always wear it in a bun, for two years straight, even sleep with it. I also have a ridiculous amount of hair, its really thick. People used to make fun of my hair.

One year ago, i decided to get it permanently straightened (japanese straightening treatment). I was really happy with the result since it was the first time in a looong time i could wear my hair loose again.

However, right now it's growing out , so literally the bottom half of my hair is pinstraight, but the top of my hair is kinda curly / undefined. I have to straighten the curly part of my hair every week as it would look ridiculous to just wear it out like this, lmao

This summer i was considering getting it permed again, but because of money, since i have rly thick hair so they charged me more for that, and the fact that i was so uncomfortable sitting 4 hours straight in the barber shop (everyone there was asian, so i was the only one with frizzy big poof hair, and i got stared at for the entire treatment).

However, i came across youtube videos of girls on their curly hair journey, and the Curly Girl Method. I still cant really tell what curl type i have, so i inserted a few pics, please comment if u can help me out lol.

Right now im planning on growing my hair out, and taking proper care of it, and hopefully define the curls and maybe ill be able to wear it out without feeling uncomfortable.

If you guys have any idea what curl type i have, pls let me know. Also any tips or stories are verryyy appreciated ! Id also love to learn more about the curly girl method since im so new to it
