adthomas, i totally agree with you about 'mixed' hair (or all hair for that matter) being different. all of our friends are in interacial marriages and the kids are all mixed (african/australian). the range of hairtypes with these kids is very interesting!!
i guess i say 'mixed' hair when talking about my daughter because she is 'mixed' (african/australian). i think i probably need to stop saying it in terms of hair type though, that's why i always TRY to say 4a hair in most posts relating to her hair!
i have seen that lady on YT, amazing! i braide/plait/wash/moisturise/style my daughters hair really well (IMO)!! some of our friends who have migrated from africa have even asked me to do their hair for them! hahaha!!! their hairtype is very different to my daughters though, i guess it would be more 4c?? it's alot coarser, less defined curl.
