If you're already a fan of Kérastase shampoos and conditioners, you'll be excited about the line's forthcoming styling product. Ciment Thermique, debuting in October, is a heat-activated "reconstructor" styling product. Meant for weak, fine and aging hair, it promises to leave hair shiny, smooth and stronger.

According to Kevin Scerbo [1], national training director for Kérastase, Ciment Thermique is designed to last up to five shampoos. It's more effective if you apply heat in the form of a hot iron or blast of blow-dryer. Priced at $34, it'll be rolling out to stylists and salons over the next month—a move intended to build buzz and get clients excited about the treatment.
