I think it was announced that the hot towels have returned for F and J with effect from 12 September, and for S and Y sometime at the end of this year.
On a separate note, I would love for the mouth wash to be returned to the onboard lavatories. Let's however count our blessings as at the very least, SQ still has got body lotion, face mist, and cologne in their lavatories in F and J, where CX has pretty much only got a fancy hand wash, hand sanitiser and body lotion now in J.
