L'Oreal Elvive Nutrigloss shampoo. I may as well not have washed my hair as it was heavy, dull and limp after washing with this crap. I don't want to think about what it would have been like if I'd used the conditioner as well.
Maybelline Dream Matt Mousse foundation. It's HEAVY and shows up every single imperfection rather than disguising it and also dried my skin.
Fructis hair gel. Ok, so it was strong hold as I wanted to make sure that the style was going to stay in place - or at least not drop too much - for several hours at an event, but even though I only used a cautious dab it set like concrete. I had a shitty time getting a comb through it in an attempt to soften it up a little and ended up having to re-wash my hair and restyle it with some cheapo no-brand mousse that did the job perfectly.
