Syoss Permanent Cool Color 5-95 Cool Light Brown is a permanent hair colour with an anti-yellow effect and 100% grey coverage. This hair colouring, based on over 45 years of experience, is designed for professional results. The cool hair colour ensures that the colour looks vibrant and feels good for a longer period of time by using the neutralising power of colour pigments. The colour cream, enriched with cool colour refl e xions and keratin, penetrates deep into the hair fibre to neutralise unwanted yellow tones, unleashing cool colours with up to 100 days of professional colour intensity and complete grey coverage. In addition, this hair colour kit contains a deep blue mask with keratin that strengthens the hair from within, while its blue pigments eliminate brassy undertones and create icy highlights. This light brown hair colour is recommended for dark blonde to medium brown hair. To apply, ensure precise, drip-free results for professional colouring. Carry out an allergy test before colouring and follow the instructions carefully. The application process includes preparation, mixing, application, rinsing and aftercare. For short to medium-length hair, use one pack; for medium-length to long hair, use two packs. For optimal hair care, we recommend the Syoss Intense Keratin Shampoo and Deep Conditioner.
