Curated Colour - 3.0-3N Dark Natural Brown

What you are looking at is Curated Colour - 3.0-3N Dark Natural Brown by Colours By Gina, a haircare product. Build-up is the usual reason a product that worked for months appears to stop working. Work it through damp mid-lengths and ends, keeping oils and masks off the roots unless the label says otherwise. 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. The best deal and the cheapest sticker price are not always the same listing once delivery is counted.
