2c with 2a &b mixed in, normal fine, normal thin, porousIf you can't seem to achieve 2nd day hair, consider trying one these. It does help keep hair from frizzing and tangling overnight.
In the dead of winter, I have a less-expensive silk pillowcase to use instead of the more easily-washable satin one I use the rest of the year. When the air is very dry, the satin makes my hair static-y, even with a humidifier in the bedroom. Silk does not cause the same static and so I can sleep without my hair tickling my face and waking me up.
