Hair Concept - Permanent Hair Color

What you are looking at is Hair Concept - Permanent Hair Color by Truss, a haircare product. Build-up is the usual reason a product that worked for months appears to stop working. Use less than you think and add more if you need it; excess product is the quickest route to a flat, greasy finish. Whether it is discounted this week says more about the shop's stock than about the product. A clarifying wash every few weeks clears build-up and lets the rest of the routine work again. The best deal and the cheapest sticker price are not always the same listing once delivery is counted.
