Davines Heart of Glass 3pcs set Sheer Glaze contains a new natural active ingredient — patented at the Davines Labs — that is sourced from the Scandinavian fir tree. This "botanical shield” comes from fibers taken from trees grown in sustainably-managed forests. It strengthens, hydrates and gives elasticity to the hair, shielding it from the heat and helping to prolong the life of your style. 1 × Davines Heart Of Glass Silkening Shampoo 8.45 fl.oz 1 × Davines Heart Of Glass Rich Conditioner 8.76 oz 1 × Davines Heart Of Glass Sheer Glaze 5.07 fl.oz
