I'm a 3A. Straighter when cut short and much curlier the longer it gets. When it is really long (BS length), it looks 3B in pictures.
3a, BSL, color treated/highlighted, fine strands (but lots of them), high porosity
Modified CG, protein lover
I'm a curly-headed runner, triathlete and foodie! Sweat, chlorine, sun... my hair gets tortured by it for 8 to 10 hours each week. It somehow always manages to 'bounce' another day!
