In the picture it looks 2b, from the way you describe it (you get ringlets also) I'd say 2b-c. It's exactly like my hair.

I don't know why on the main site they take hair width into consideration. Makes no sense to me.
fine - low/normal porosity - medium density - normal elasticity.

Currently using:
Cowash: Cure Care diluted with water 1:1
RO: Cure Care, V05 Kiwi Lime
Styler: UFD CM (old formula), FSG + CNPF
PT: IAgirl's gelatine

Experimenting with: no guar hydroxypropyltrimonium chloride, gelatin gel

Recent findings: my hair likes Cure Care diluted with water as a cowash; does NOT like guar h.c.!
