GENERAL ADVICE. Hair colours can cause allergic reactions that may be severe in some rare cases. In any case, a skin sensitivity test must be carried out 48 hours before each application of this colour, even if you have previously applied this product or another colour to your client, as allergies can develop suddenly.

SKIN SENSITIVITY TEST: remove any earrings. Using a cotton swab soaked in the colouring product (not mixed with the oxidising agent), apply it behind the ear or on the inside of the elbow, covering an area the size of a penny (1-2 cm²). Let it dry and apply again. Carefully close the colouring product packaging. Wait 48 hours without washing, covering or touching the patch. If you or your client experience abnormal reactions such as itching, redness or swelling in or around the area being tested during this time, do not use the hair colour.

A hi-tech formula for healthy hair: Free is the permanent oxidative colour developed by the K-time laboratories to offer unprecedented professional performance without the use of resorcinol or ammonia, protecting the natural structure of the hair.

Free from ammonia, resorcinol, PPD (paraphenylenediamine) and parabens, Free hair dye is exceptionally gentle. During the oxidation phase, the pigments penetrate into the deepest layer of the hair structure without damaging the fibres, fragmenting to ensure greater adherence to the hair: the result is an explosion of vibrant and intense colour combined with healthy hair.

The formula of the Free permanent oxidative hair colour is enriched with hyaluronic acid and argan oil, which perform restorative and nourishing actions: known for its cosmetic properties, hyaluronic acid keeps the hair hydrated, bringing new softness and elasticity.

Argan oil, on the other hand, strengthens the intercellular cement to revitalise, protect and deeply nourish the hair fibres. Thanks to its gentle and nourishing formula, the Free permanent oxidative dye offers vibrant and long-lasting colour, without sacrificing glamour: a variety of shades to achieve the pinnacle of colour and beauty.
