WHAT’S NOW & HOW TO DO IT...

DOUBLE MOUSSING

MOUSSE is back! Unlike the sticky products of the Eighties, which made hair stiff and crispy, the latest formulations feel nourishing and leave you with soft and shiny tresses.

To make the most of its effects, follow the trend for doublemoussing — a backstage catwalk trick where two layers of mousse are used to make hair look fuller and thicker. Comb it through wet hair, then add another layer when it’s 85 per cent dry, before finally drying it fully. L’Oreal Professionnel Tecni.Art Rebel PushUp ( left, £15, feel unique.com) gives volume without stickiness, while Umberto Giannini’s soft, creamy Mermaid Hair Volume Mousse (far left, £7, boots. com) contains coconut oil, which hydrates and smooths to boost shine.
