Key Ingredients, Explained

• Ashitaba extract: Known in Japan as "the tomorrow leaf," this ancestral plant is sourced from Hachijō-jima island and is rich in antioxidants, vitamins and minerals for smoother, shinier, healthier-looking hair.
• Ferulic acid: A powerful skincare antioxidant, found in rice and coffee seeds, that helps protect the hair fibre and preserve its vitality, strength and shine.
• Panthenol: Binds to the hair fibre to leave a weightless, protective veil, so hair feels smoother, softer and more manageable.
• Biotin and caffeine: Complete the formula for a revitalized scalp feel and fuller, healthier-looking hair.

How to Use

Curious Stylist Tip

Squeeze excess water out of your hair first. A mask works better on damp hair than on soaking-wet hair.
