What texture is my daughter’s hair?

Now I have texture 4 hair. Some places are 4a but the majority is 4b/4c. I think my daughter’s hair is 3b/3c but I think I’m wrong. I’m not really used to her hair texture. While mine is very dry and needs much attention, hers is very soft and fine. I feel that the products I use may be too much for her hair. I don’t put many products in her hair. I use a brand called trepadora but it is becoming expensive to repurchase. I sometimes just wet, comb and put Haitian black castor oil. I would like some cheap alternatives if possible. I’m not too fond of Cantu brand and shea moisture is so overwhelming with the different lines they have. Thank you in advance!
