At first glance, it looks like another ‘blue shampoo’, but it’s more sophisticated than most. Instead of relying on harsh synthetic dyes, it uses a natural blue extract from jagua fruit to gently balance out warmth and brassiness in blonde, silver, and grey hair.
The pigment is subtle enough for daily use (no risk of over-toning or dulling), yet effective enough to keep grey hair looking luminous and clean. But tone is only half the story. What really makes Heart of Glass shine is its care-first approach. Grey hair can feel coarse, wiry, or brittle, and this shampoo is formulated with Baobab extract, known as a natural alternative to silicones.
It softens and smooths the cuticle without heaviness, leaving hair supple rather than coated. There’s also Fortifying Botanical Shield technology, which helps protect strands from environmental stressors and heat damage – particularly important for hair that already lacks the natural melanin protection it once had. The texture is lightweight and gel-like, producing a creamy lather that rinses clean without stripping. After just a few washes, grey hair looks brighter, feels softer, and gains that healthy, reflective sheen that’s so essential for silver tones.
