The Toppik Coloured Hair Thickener (£19)is a tinted hair spray that can help solve a variety of hair woes, whether that's concealing your roots when you can't make it to the salon right away, adding some volume to limp strands, or concealing areas of thinning hair if that's something you wish to conceal. The spray comes in four shades (Light Brown, Medium Brown, Dark Brown, and Black) and is not only water resistant (so you don't need to worry about getting caught in the rain), but it also promises to not rub off on your clothes or bed sheets.
