I just used Tweek on 2nd day hair and it turned out pretty good. I woke up late, so I just spritzed my hair with some water to get it a little damp, put some Curl Keeper
on top then quickly diffuser-dried it (didn't take long since it was only damp). After that I rubbed some Tweek between my hands and scrunched it in at the roots. Turned out pretty good. Not as good as if I had washed it, but pretty good.
