The hairdresser has been highlighting blonde my naturally dark brown hair for ages. I have tried going back dark on a few occassions and never been happy so i've always gone back to highlighted. My highlights are now dull and i'm fed up with hair never being shiny and roots showing through. I really want the lovely glossy, healthy brown hair others seem to have. I cannot afford to go to the hairdressers so I've bought a Loreal Casting Creme gloss in shade Chocolate. It says on the box it's ideal for covering highlights. It's a semi lasts about 28 washes) but in my experience they never seem to wash out. The shade has some warmth in it by the looks of the box. Shall I do it???? I start a new job on monday and don't want a huge disaster but it seems quite safe according to what it says on the box. Has anyone got any experience of doing this, or this shade?? thanks!
