The mixture between deep blue hues, silver strands and pastel blue blonde makes denim hair the coolest color combination there is. No pun intended but this cool, steely color palette is one to watch out for at the minute. Many brands are releasing deeper blues, steelier grays and colder silvers as everyone fights to achieve such striking looks! The denim shades of blue are perfect for a splash of statement yet subtle, quick color. Wether it be spray in color, hair chalk or hair dye, we dare you to try!  Check out my previous blog on Jerome Russel Denim Toner and have a go at trying this out for yourself!
