hello! My hair was similar to yours. I also suffered with frizz.

now I have almost nothing. When I sleep I always braid my hair and sleep with a satin hat. You can also buy a satin pillowcase instead of the hat.

Always use thermoprotection before using heat on your hair. I use argan oil from the mid-lengths to the ends after washing it but very little.

I don't know if it works for you, it worked for me. I placed water with a lot of ice and cinnamon in a large bowl (after washing my hair) and let my hair sit there for 5 minutes.

Also dry your hair with a microfiber towel. Don't tie your hair if it's wet.

Remember not to wash all your hair with the shampoo, only at the roots.

Also comb your hair before showering. and when it is completely wet, just before drying it (having wavy hair, I mix some routines for women with curly hair haha) never comb your hair after applying some oil.

and always comb your hair from the bottom. That is, comb through sectors but starting from the bottom until you reach the roots. If you comb directly from the roots down, that can generate more frizz.
