There are so many reasons why you should incorporate Sisley’s Hair Rituel Revitalizing Volumizing Shampoo with Camellia Oil into your haircare routine. The first clue is in the name; camellia oil combines with shea and hazelnut oil to soften, smooth and improve the shine of every strand, and the second is in its fine texture that transforms into a rich foam, rebuilding the hair’s protein and lipid structure for fuller, bouncier tresses.
