Keep your salon colour looking fresh from the very first wash. Biolage ColorLast Refill Shampoo 500ml is a colour-protecting shampoo made especially for colour-treated hair, gently cleansing while working to hold onto your shade. Its clever low pH formula cleanses without disrupting the hair, helping to maintain colour depth and tone wash after wash. And as a refill, it's the kind, cost-effective way to restock, cutting down on packaging waste while topping up your favourite shampoo.

The colour care comes from soybean oil, which protects and nourishes the hair while helping to preserve your colour and prevent fade for up to four weeks*. It's the gentle, everyday cleanser that lets you get more mileage out of every trip to the salon, keeping colour-treated hair looking vibrant and feeling cared for rather than stripped or dulled.

What it does for coloured hair

Colour-treated hair needs a gentler approach, because the wrong shampoo can lift and fade your shade every time you wash. A low pH formula like this one helps keep the cuticle smooth and closed, which is exactly what holds colour in and keeps it looking true. Used regularly, it slows down fade, maintains depth and tone, and keeps your colour looking salon-fresh for longer.

How to use it

Apply to wet hair and massage gently into the scalp and lengths, working up a lather. Rinse thoroughly and repeat if needed, then follow with the matching ColorLast conditioner for the full colour-care system, which is how you'll get the full up-to-four-weeks colour protection benefit*. You'll find the matching conditioner and more in our professional shampoo collection.

Who it's for

This one's for anyone with colour-treated hair who wants to keep their shade vibrant and true for as long as possible. It's suitable for all coloured hair, and like every Biolage formula it's vegan with no animal-derived ingredients and certified cruelty-free under the Leaping Bunny programme. We've been perfecting colour for clients in Codsall for years, so we know exactly how much difference the right aftercare makes, and a low pH colour shampoo like this is the perfect foundation for protecting your colour between salon visits.
