About K89

K89 is a Spanish professional haircare brand founded in 2010 and part of the Vitafrán group. It began by responding to demand for specialist keratin treatments and care for damaged hair. The K in its name refers to keratin, while 89 marks the start of the Vitafrán family business in 1989.

Hairdressers and salon work are central to the brand. Its portfolio combines technical colouring and treatment products with everyday care and finishing products. Professional training supports the range, helping hairdressers choose an approach suited to the condition of the hair.

What is K89 known for?

K89 focuses on damaged hair, hydration, smoothness and frizz control. Different ranges address intensive care, curl definition, shine and colouring. This makes it possible to select products around a specific concern and hair type rather than build every routine around the same formula.

K89 products

Shampoos, conditioners and masks

Shampoos, conditioners and hair masks form the basis of regular care. Consider dryness, the extent of damage, hair texture and the desired finish when choosing a product. Follow cleansing with a suitable rinse-out or leave-in treatment.

Intensive Care

Intensive Care brings together treatments and maintenance care. The brand describes Wizard System as an intensive hair-fibre treatment with collagen, amino acids and vitamin E. The range also includes a preparatory shampoo, finishing serum, maintenance shampoos and a mask designed to complement the treatments.

Professional Curly Hair

Professional Curly Hair is designed for wavy and curly hair, following the principles of the Curly Method. Its priorities are hydration, defined and elastic curls, and reduced frizz. K89 emphasises the role of a hairdresser in selecting products and routines for the individual hair type.

Global Glow and hair colour

Global Glow targets shine, hydration and frizz control, with cotton, rosehip and argan extracts highlighted in its formulas. Permanent hair colour is another part of the professional portfolio. K89 describes 4D COLOR EXPERTS through four aspects: depth, shine, coverage and care.

Who are K89 products for?

K89 suits hairdressers and customers seeking targeted care for dry, damaged, coloured or curly hair. For home care, choose a product intended for your hair’s condition. Technical colour and salon treatment products should be used according to their professional protocols. Compare individual descriptions to build a routine around your needs.
