COSMETIC CRAVING

WHEN beauty enthusiasts fell in love with hyaluronic acid as a facial hydrator, bright sparks started applying it to their hair, too.

However, waxes and oils are also required for this wonder ingredient to coat the hair cortex, otherwise it pulls water from the environment, creating frizz. L’Oreal Elvive’s bestseller, Hydra Hyaluronic Moisture Plump Serum (£12.99, boots.com) cracks this — and at a supercompetitive price. It’s often on special offer, too.

With a few nourishing spritzes, it feeds brittle, dehydrated locks, plumping and smoothing the cuticle, and instilling immediate volume, shape and bounce. It is suitable for all textures, and can be used on wet or dry hair, and pre-styling, post-styling or instead of styling. Get some.
