Who doesn't love a hair mask to give their hair a fresh, shiny boost? We certainly do, and there's a newbie we'll be adding to our stash this year. The L'Oréal Paris Elvive Full Resist Power Mask (£13) is intended as a weekly treatment mask, containing a cocktail of ingredients such as biotin, vitamin B5, and arginine, which promises to help strengthen weakened hair due to shedding and breakage. Eve more reason to add this to your haircare regimen: In September, the brand announced that all of the Elvive bottles would be made from 100% recycled plastic from here on out, saving approximately 900 tonnes of new plastic in the UK annually.
