I feel like NC is so forward in its approach to highlight curly hair...yet kind of undoes everything with this hair type stuff in every corner. It makes me cringe that product suggestions are given based on hair type. It also renders the reviews useless because it doesn't ask the reviewer their hair thickness. People write their hair type and jump straight to the review...yet I'm still wondering if it'll work for me.

You're 100% right, hair thickness is overlooked here and along with porosity it's the most important hair property. This mistake should be corrected.
