Our Super Nutrient Purple Shampoo is gentle, caring, and naturally effective! Specially crafted for blonde, silver, grey and lightened hair, it helps neutralise brassy tones while nourishing your hair and scalp so they look and feel their best. Pair it with our Super Nutrient Purple Conditioner for the complete ritual. We make it using 100% natural ingredients, including a high volume of organic seaweed, herbs, and plant-based pigments from Blue Seaweed, Alkanet Root and Cape Jasmine Fruit. These natural colours deliver a vibrant purple tone without synthetic dyes, helping to brighten light hair gently and naturally. It is suitable for all hair colours, types, and scalps — especially those looking to maintain blonde, silver or grey hair with a kinder, more natural purple shampoo. It’s free from silicones, SLS, parabens, artificial fragrances, colours, sulphates (including natural sulphates), is never tested on animals, and is vegan friendly. We include our in-house extracts made from organic Seaweed, Tuber Fleeceflower Root, Angelica Sinensis Root, Frankincense & Mint Leaf — along with gentle, plant-based cleansers and essential oils, carefully balanced to a scalp- and hair-friendly pH level.How to use: To neutralise yellow or brassy tones, use with every wash until your desired tone is reached. Then, use weekly or as needed to maintain brightness and balance, alternating with our regular Super Nutrient Shampoo & Conditioner. We’re sure you will love it as much as we do!
