I'm a big fan of Kérastase products, although I'm not a fan of the price tags. Except once you try the products you have to admit that they are worth the cost. The newest product is no exception, Kérastase Elixir Ultime is by the far the best smelling hair serum I've ever used. It's really like a perfume for your hair! Formulated with a combination of four oils (Maize, Argan, Camellia, and Pracaxi Oil) it's surprising that it's so incredibly light even on fine hair. Even when you use it before cleansing, after conditioning but before blow drying, and as an added shine enhancer it STILL won't weight down your hair. In a battle between Shu Uemura Essence Absolue this wins hands down so save yourself the $15.00 and just pick up Kérastase Elixir Ultime.
