Napiers Herbstrong Hair Conditioning Mask is a deeply nourishing treatment for the hair and scalp, inspired by an original 1860 herbal recipe from Duncan Napier. Formulated with rosemary extract and a powerful blend of 12 additional botanicals, including green tea, ginger, mulberry and fleece flower, this intensive mask helps to strengthen, smooth and rejuvenate the hair.

Free from artificial fragrance, parabens, sulphates and phthalates, it reduces tangles, enhances shine and supports a healthy scalp, leaving hair soft, strong and full of vitality.
