"I was turned on to these hair food masks by women in the UK who're following the curly girl method. The Garnier Ultimate Blends Hair Food Papaya 3-in-1 Damaged Hair Mask Treatment (£3.50, originally £7) is formulated without silicones or sulphates, which can help to keep your natural curl or wave intact, but they're also just really great does-it-all hair conditioners for most hair types (there are a few different 'flavours' but this fruity one is my favourite). You can use the product as a mask, a regular conditioner, or even as a leave-in treatment. The pots are huge and last ages even if you use loads like I do, and as a bonus, they always seem to be on offer: I don't think I've ever paid full price."
