The Moroccanoil Colour Depositing Mask Mini ($7) nurtures hair while also enhancing its colour. There are hydrating amino acids alongside softening argan and apricot oils in all varieties of this deep conditioner, but there are several colours to choose, from champagne (for lighter colours) to bordeaux (for deeper browns). Each one can extend the look of colour-treated hair or play up that colour with a different undertone like blue-toned aquamarine or pinky hibiscus.
