Ooooh exciting! I think information about your hair type and properties, a slow 360 degree view of your hair so we can see the different curl patterns, a 'before' photo if you can edit one in, the bare bones of your routine. Not necessarily detail about products and techniques but that you follow Curly Girl or a modified version (if you do).
Obviously some of it would be stuff we on NC would know, but I'm thinking if newbies found your channel by searching YouTube they might be totally unaware of CG and hair properties. Maybe then just tell people what you are thinking of covering in future videos, be that tutorials or reviews or whatever?
