Full product name: Anti-Brass Hair Mask
Hyaluronic Acid is the go-to skincare ingredient for moisturisation, with every molecule able to hold at least 1000 times its weight in water. This helps to reduce hair and scalp dryness – without feeling greasy or causing build-up – leaving hair shiny, soft and healthy with bounce, while also taming flyaways and frizz.
Moisturising the hair is even more important when it is bleached and dyed, as it can become dry, dull, faded, weak and prone to breakage.
Amino Acid
Made of amino acids which are the building blocks of healthy hair structure. These help protect hair from damage and dullness due to dehydration. They also help to revitalise and strengthen the hair, providing moisture-rich, resilient, and silky-smooth strands from the root.
