Making refills look as good as they are for the environment, L’Occitane‘s value duo contains a 500ml refill with the 250ml Verbena Shower Gel. We also love it for the crisp citrus scent, combining the essential oils of verbena, orange, geranium and lemon tree.

Aveda‘s sustainability credentials are impressive, and one example of where they’re winning is with the extensive range of supersized versions of the brand’s range of shampoos and conditioners. Available in one litre bottles, they cost 20 per cent less per ounce and use up to 28 per cent less plastic. The silicone-free Shampure version contains 95 per cent naturally derived ingredients and suits all hair types.

While we love the blush coloured metal tube packaging of the smaller sized Aesop hand balms, this 500ml version made of sustainable plastic is just as #shelfie-worthy. The aromatic moisturiser blends natural oils and extracts that are as good for your skin as they smell.

It’s the cult classic that everyone from beauty editors to Hollywood’s finest swears by for hair repair – so it’s no wonder the Philip Kingsley Elasticizer is available in a supersize package. Enriched with castor and olive oils, it locks in moisture for softer, silkier hair as well as preserving the life of your colour.

Here’s another classic. We’re yet to meet a make-up artist without this in their kit, and like them we’d do well to stock up on the cost effective 500ml version, with its convenient reverse pump dispenser.
