Long hair is a challenge, say the experts from Kérastase. While roots can be oily, lengths suffer from damage. That’s why Kérastase has created Cristalliste, a collection designed to preserve the hair’s lipid film, keeping it supple and strong from root to tip. There are two **Luminous Perfecting Shampoos, $39 each (1),
one for thick hair, one for fine, a Conditioner $47 (2) and a leave-in Perfecting Essence $40 (3). My tester loved the new range, which left her very long, fine hair amazingly soft and silky. If Cristalliste** is beyond your budget, apply your regular conditioner only from the mid-lengths to the tips and use a dry shampoo to deal to any grease in the roots the next day.
