Watercolors DD Intense Color - Blue Spruce

What you are looking at is Watercolors DD Intense Color - Blue Spruce by Tressa, a haircare product. Build-up is the usual reason a product that worked for months appears to stop working. Rinse thoroughly — residue left in the hair dulls it more than hard water does. Discounted listings come and go, and rarely at the same shop twice. Store it away from steam and direct sun; both shorten the life of the formula. Add delivery to the cheapest price and you will see whether it is genuinely the best deal.
