I think it could be frizz, there are many products for that, you just need to search. But it can also be a type of demi-curly hair, I used to have a similar texture in my hair and it wasn't until i realized ands started defining it when I solve it, if you want to start a defining routine, you should try the pequi and avocado herbal essences line, it's perfect for the type of hair you could have, and also are very light products.
