The PhytoMillesime Color-Locker is a pre-wash colour treatment that preserves the vibrancy of colour by locking pigments inside the hair fibre. The gel-oil formula gently coats the hair, creating a protective shield to prevent colour from fading. Ideal for colour treated and highlighted hair, this pre-shampoo wash helps to create a protective barrier, trapping pigments and preventing colour fade and leaving hair bright, vibrant and healthy.
