In short: richer colour, better condition, and a noticeable boost in shine, all in the time it takes to have a cup of tea.

REF Colour Boost Masque Ash Brown is a clever little upgrade for tired, flat brunette tones. More than just a conditioning hair mask, it works as a toning treatment that reinvigorates your colour in just 10 minutes, ideal when your brown starts looking a bit dull or brassy.

Designed to refresh both natural and colour-treated hair, this masque delivers a subtle, cool enhancement that brings back that rich, ashy depth brunettes are best known for. Your brown hair looks deeper, softer, and far more intentional, like you’ve just stepped out of the salon.

Formulated with quinoa protein and natural pigments, it doesn’t just sit on the surface. It helps strengthen the hair fibre, improve overall condition, and boost pigmentation where it’s needed most. At the same time, it provides essential hydration, smoothing the hair and leaving it silky to the touch.

It’s particularly good at keeping brassiness in check, no unwanted warm tones creeping in, while enhancing shine for that natural, healthy gloss. After just one use, your hair feels softer, looks more vibrant, and carries that polished, salon-standard finish.
