Wow, what a difference. I tried pineapple-ing and wrapping a scarf around my hair, unfortunately I couldn't sleep like that so I pineappled and plonked my sleep cap on and today ..... there is NO frizzyness. None whatsoever. And no dryness feeling. I guess that means my original sleep method was creating a lot of frizz and thus creating the illusion of dryness. I'm thrilled!
I'm also happy that I can continue trying to stretch my washes w/o worrying that my hair will dry out in the process
