Cute hair!! Awesome ringlets! Curl type isn't as important as porosity and texture, though, so I would focus on finding out what you're working with. I agree you're probably 3b-3c, but like most curlies we have a mix of curl types on our head including some straight pieces, at least for me, lol.
2C/ Coarse/ Normal porosity/ SW Florida/ Salt & Pepper
