The Biolage ColorLast Deep Treatment Pack is a hair mask that provides intensive care for coloured hair. The mask helps to care for coloured hair and at the same time protects against colour fading. The mask cares for your hair by restoring the natural moisture balance and strengthening the hair follicles, making hair feel soft and stronger. This is partly due to the added apricot seed extract, which contains many vitamins that improve the elasticity and strength of the hair. The colour intensity is protected by the addition of Orchid. This plant has intense colours that are protected from UV radiation and discolouration by powerful flavonoids. This also works well for the colour intensity of your hair. Because the entire hair is well taken care of, your hair will be softer, stronger and its breakage will be reduced.
