Kérastase Blond Absolu Strengthening Conditioner This Kérastase Blond Absolu Strengthening Conditioner ($40) is not as rich as a mask, yet it still nourishes blond hair whether it's in a balayage, highlighted, or bleached style. After all, the mask offers the same benefits of hyaluronic acid (to strengthen hair fibres and leave hair silky), but in a more lightweight formula that can be used daily.
