Purify Plus Lite

What you are looking at is Purify Plus Lite by Keracolor, 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. A discounted listing is only a saving if it is the same size and edition as the one beside it. A clarifying wash every few weeks clears build-up and lets the rest of the routine work again. The cheapest listing is not automatically the best deal: delivery and any code applied at checkout decide that.
