Is my hair 2a or 2b?
I can't really tell. I'll get random spiral curls through out sometimes. Thanks in advance!
I think I'd go with 2a.
They are loose here but they are more like small bends not large ones. Since you said that you get spirals sometimes, it makes me think that they are 2b with potential to be more under the right circumstances! The Curly Girl Method is what you need. My hair was so similar and has really sprung to life since I cut silicones and sulfates and started following CG a few months back! Try it -- often times it can be less expensive than what you might already be doing!
