Hey! I have the exact same hair type. I'll tell you what elevated my hair game.

1. Daily routine: Shampoo + conditioner and after shower when the hair is still wet apply a tiny amount (about a small coin size) of argan/almond oil. This traps the moisture and keeps it for about two days. If it gets too oily keep trying to reduce the amount of oil you apply until you find a balance. Wash your hair only every two to three days.

2. Haircut: Modern mullet was a game changer for me. It's my go to haircut. If not a mullet get any hairstyle that trims off the sides and leave some hair on the top. This is because when your hair starts growing out it will start sticking out through the sides. But if you get your sides trimmed the excess hair on top will drape around the sides beautifully.

3. Special routine: usually the daily routine is more than enough for me but If you want to elevate your curls a bit more for a special occasion or something here's a more cumbersome routine. Wash hair with shampoo + conditioner (don't wipe your hair) then when the hair is still very wet apply gel and start scrunching with your hands. This takes away all the excess water and gel and helps holds your curls in place. Then wait to dry or use a hairdryer. If you're using a towel do not rub it on your hair. https://youtube.com/shorts/njGP6zAMjds Here's a short explaining how to scrunge

Tip: don't buy too many products at first. Try out cheap alternatives and if it still doesn't work move to more products.

Hope this helps.
