Small sticks are easy, if not fun to use! We wet them a little, then we color the troublesome strands. We let dry and voila! The chalk will stay in place until the next shampoo! Even more express than the previous solution. By applying the spray method, the colored spray is focused, long lasting and extremely easy to use. After coloring the roots, spray on your favorite hairspray to anchor the temporary color and ensure that it resists friction.
