The surge in demand for restorative haircare helped boost L'Oreal's second quarter sales by 6 per cent. Its boss, Nicolas Hieronimus, said customers suffering hair loss from 'fat jabs' are seeking to boost volume and promote regrowth. There were double-digit rises in hair brands such as Dove, Sunsilk and K18, too. K18 now offers FutureIQ Biomimetic Hair Longevity Serum, which addresses premature hair ageing. But Unilever is also betting on more affordable items to pull ahead in the hair skin-ification game.
