IMO, a Hot Sock is only slightly better than no diffuser at all. I only use mine in a pinch when traveling - never if I have any other sort of diffuser available . . . .
Also, IMO, soaking wet hair, regardless of how I achieved it (right out of the shower or adding some back in from the faucet or by spraying), has always
worked best for me, especially on first day. If I do it on first
day, I can usually get good enough succeeding days without
having to wet it so much - which saves me a lot of time on those days.
