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, 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.
