I've had a colour cleanse, but being impatient, I wanted a quick fix to get a lighter, brighter barnet. Here is where L'Oreal Casting Sunkiss Jelly steps in. You might have seen the adverts on TV plastered between every show, with this little tube promising to give you that gorgeous holiday sun-bleached hair packed with natural highlights.
