Okay, so it's not <em>really</em> caviar in this new treatment from <a href="http://www.kerastase-usa.com/_en/_us/conso/home/home.aspx" target="_blank">Kérastase</a>, called <a href="http://www.kerastase-usa.com/_en/_us/conso/products/chronologiste/waitlist.aspx" target="_blank">Chronologiste</a>. It's something called "mimetic caviar," which I understand is a lab-derived equivalent. (Because really—who wants their hair to smell like fish eggs?)

Anyway, listen up, because this is probably the most decadent hair treatment I've ever come across.
