REF Colour Boost Masque Ash Brown

Colour Boost Masque Ash Brown 4.1 by REF.

An easy upgrade to your colour routine, richer colour, better condition, and noticeably smoother, shinier hair in just 10 minutes.

REF Colour Boost Masque Ash Brown is a smart fix for brunettes when colour starts to lose its edge. Acting as both a nourishing masque and a toning treatment, it reinvigorates your shade in just 10 minutes, bringing tired brown tones back to life with minimal effort. 

Suitable for all hair types and lengths, REF Colour Boost Masque refreshes both natural and colour-treated hair with a subtle, natural-looking enhancement. It adds that sought-after ashy depth, giving brown hair a cleaner, more refined look without overdoing it.

Enriched with quinoa protein and natural pigments, it works beyond the surface to strengthen the hair fibre, improve overall condition, and increase pigmentation where it matters. It also delivers a boost of hydration, helping to smooth the hair and leave it feeling silky and soft.

Designed to prevent brassiness, REF Colour Boost Masque Ash Brown keeps unwanted warm tones at bay while enhancing shine for a natural, healthy-looking finish. The result is hair that feels stronger, looks more vibrant, and carries that salon-standard shine.
