This natural-origin formula is perfect for targeted application and adapts to the natural base colour of your hair for a seamless finish. Achieve a Subtle & Elegant Look in Just 20 to 40 Minutes With a short-term fix that fades gracefully and evenly in 5 to 7 washes, there's no need to worry about a 'helmet' root effect. In just 20 to 40 minutes, this color gel will leave you with a subtle, elegant, and luminous result that enhances vibrancy. Nourishing Care for Sensitive Scalps Suitable for all hair types and sensitive scalps, Christophe Robin Temporary Color Gel is free from harmful chemicals like ammonia, peroxide, resorcinol, PPD, silicones, and SLS. However, if your hair is very porous, it's best to apply a nourishing care onto the lengths during the gel's leave-in time to avoid any unwanted results. Preserving & Brightening Formula Enriched with Inula Flower that preserves and brightens hair color, your hair will look shiny, soft, and vibrant. Oats' antioxidant virtues provide maximum tolerance, which protects the skin and scalp. Not Suitable for Bleached Hair or Highlights Please note that Christophe Robin Temporary Color Gel is not suitable for bleached hair or highlights more than two shades lighter than the base colour. Rest assured, this dermatologically-tested gel will give you a natural and seamless finish every time.
