Alterna Caviar Anti-ageing Red Shampoo is a enzyme based care product designed to revive and restore dull, dry red hair. It targets the signs of ageing for healthier more youthful looking hair, whilst protecting your red tones and keeping unwanted secondary hues from surfacing. Neutralising blue/purple tint offers progressive tonality without using colour deposits that change the shade of your hair colour, to leave your locks with multidimensional shine and vibrancy.
