Some pictures would really help, but you're definitely a 2-something. Brushing your hair when it's dry is a no-no for curl definition – that's why it's poofing! I'd suggest you ditch the brush and only detangle your hair the days you shower. Smooth/scrunch some leave-in into your hair to refresh it, but don't brush it through.
Also, more important than your curl type are your hair's properties (texture, porosity, etc). Check out Live Curly Live Free - Curly Hair Basics – it'll help you determine what your hair will thrive on. Hope that helps!
