About the range
Shades within the Vero K-PAK Color palette can be intermixed to adjust depth and tone. Alongside standard shades, the range includes high-lift shades, toners and concentrated pigment additives. These serve different purposes: lightening natural hair, refining tone after bleaching or intensifying the base colour's tone.
Quadramine Complex is the range's protein complex for repairing and protecting the hair structure. Trans-Cuticle Delivery technology supports dye penetration into the hair. Toner and High Lift formulas also contain lecithin, which helps soften and condition hair.
Mix standard colours with Veroxide at a one-to-one ratio, and High Lift and Ultra High Lift shades at one-to-two. The specific service determines the developer strength and processing time. After rinsing out the colour, use K-PAK Cuticle Sealer and K-PAK Hydrator in the range's specified conditioning sequence.

About Joico
Joico is an American professional haircare brand with a history dating back to 1975. Its main specialities are haircare, restorative treatments, styling and professional hair colour. The portfolio includes products for salon services alongside everyday care for use at home.
Its collections address different needs, including dryness, breakage, colour fading and unwanted changes in tone. This makes it possible to build a routine around your hair's condition, thickness and previous chemical treatments.
What is Joico known for?
Joico is particularly associated with K-PAK and protein-based care for damaged hair. Selected formulas feature SmartRelease technology, a liposome system that gradually releases rosehip oil, arginine and keratin. It is designed to help strengthen hair and protect it against damage associated with daily styling.
Ingredients and priorities vary across the collections. K-PAK Color Therapy features argan and manketti oils, while Color Balance uses pigments to help correct unwanted warm tones. Check the individual product description to distinguish between moisturising care, restorative conditioning and tone maintenance.
