L’Oréal Serie Expert Volumetry is design for fine, limp hair. Serie Expert Volumetry line is enriched with Intra-Cylane molecule capable of penetrating the core of hair fiber from the inside out. In the result hair looks dramatically thicker with exceptionally light and pleasant scent. The great part about Intra-Cylane is that it doesn't completely wash out, so more often you use L’Oréal Volumetry products, the thicker your hair will look.
