A maximum strength formula that removes yellow tones from blonde, bleached, grey and highlighted hair in minutes. Or, leave for longer to allow over-toning to take place for lilac and purple hues to appear. This hydrating formula leaves hair more manageable, prevents fading and adds shine. For perfect blonde haircare maintenance! HOW TO USE Apply to wet hair, lather and massage into the hair. Leave for 1 to 5 minutes. Rinse thoroughly and repeat if necessary. Ultra Blonde takes very quickly to pre-coloured or bleached hair. In this case, mix with MUVO Totally Naked Shampoo for the desired tone. Follow with MUVO Ultra Blonde Conditioner. Use once or twice weekly or as required to control brassiness.
