OSiS+ Mighty Matte

OSiS+ Mighty Matte by Schwarzkopf is catalogued as 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. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
