Day 17 in Debenhams is a Ouai leave in conditioner, which is my number 1 for holidays and summer when the sun frazzles my hair!
I'hve seen this everywhere, so i am glad to have a bottle to try out!
The Book of Beauty from Marks& Spencer day 17 is a Balance Me eye cream, which i MAY use after the heavy nights of the festive season, but it isn't something I love really. Sorry! Its a pretty great size though, so i may just pass it on to a friend!
