Love your hair it's so pretty
I haven't used Eco Styler (not a fan of gels at all) but thought about giving the Krystal brand a try.
From looking at your pictures, your hair looks a lot like mine when its wet and some people say I'm 4b and a lot say I'm 4a. Hair typing is so confusing I only go by the standard straight, wavy, curly, kinky. No need to add any extra categories.
PS: From what I hear its best to type hair when its naked (no product in it at all)
