Finding a hair treatment that keeps colour-treated tresses bright and brass-free while leaving hair silky smooth is no easy task.

Over 30,000 beauty fans on Amazon have given the Bold Uniq Purple Hair Mask a perfect rating

Over 30,000 beauty fans have awarded the mask a perfect rating praising it for keeping colour-treated hair looking fresh, brighter and blonder for longer, knocking brassy tones out of blonde, bleached and highlighted strands quickly and effectively.

Packed with dark violet pigment, the Bold Uniq Purple Hair Mask helps ‘reverse any yellowing’, bringing out cool, bright tones in just one application.

The brand description reads: ‘This purple hair mask helps neutralise brassy tones, keeping your blonde ice cool, while reducing breakages and split ends.’

Formulated with vitamin B5, soy protein and ‘super’ oils, the vegan treatment protects hair against colour fade and leaves locks’ super soft’, ‘conditioned’ and ‘healthy’, according to shoppers. Plus, it’s also sulphate- and paraben-free.

In fact, reviewers say the Bold Uniq Purple Hair Mask is the ‘best toner’ and ‘better than the purple toner used in my hairdressers’. Others have advised only using the mask once every two weeks in order to avoid ruining the colour.

‘UNBELIEVABLE!!’ one user raved. ‘My hair is literally like yellow straw since I’ve been bleaching it, and feels like the ends are burnt/singed, and as soon as I dry and straighten it I put it in a bun on the top of my head its that bad!

‘Brought this cos it was cheap and thought, why not another hair treatment that will probably go in the hair box, but WOW…. it’s soft, a lot lighter and ends look and feel smooth, and by the look of it will last at least 6 months.’

They added: ‘Cannot wait to use a second time if the first is this amazing and finally be able to wear my hair down.’

‘My hair is balayaged and the ends looked really yellow and rather dry,’ a second shopper explained. ‘One application has totally transformed my hair! It’s now a much nicer colour and really soft!’

A third user wrote: ‘I am completely in love with the smell of this; it’s divine. SO hydrating it will force smoothness and softness into the driest hair.’
