The product information specifies it suits 'coloured lengths that need a gentler cleansing touch'. This indicates the formula is designed to cleanse without being overly harsh, which can help maintain colour vibrancy. The sea-buckthorn's smoothing effect can also help coloured hair, which is often more porous and prone to feeling rough and looking dull.
For coloured hair, it's advisable to wash with cool or lukewarm water, as hot water can open the hair cuticle and accelerate colour fading. While this shampoo may help hair 'feel softer from root to tip' and improve 'fuller appearance', protecting colour longevity also depends on minimising heat styling and sun exposure. If your colour-treated hair is extremely dry or damaged, pairing this with a conditioner or mask formulated for colour care is recommended for optimal manageability and shine.
