Oligo Rio Rio Crystal Clear Semi-Permanent Hair Color 3.4oz/100ml Explore the wildly colorful world of RioRio, a semi-permanent hair color inspired by the Rio Carnival, and everything that is Brazil. Infused with vitamin E, a powerful antioxidant, RioRio provides ultimate conditioning for the shiniest-looking locks. Each shade is highly pigmented, allowing you to achieve unbelievably vivid results when applied directly on the hair, or more subtle effects when mixed with the CRYSTAL CLEAR. Plus, RioRio shades are inter-mixable, offering endless color options! In addition, RioRio features the Colour-Lock Technology which is a synergetic combination of ingredients (Behentrimonium chloride, Dimethicone, Hydroxyethylcellulose et tocopheryl acetate) that prevent excessive bleeding, staining, and fading of color. The specially selected compounds are attracted only by hair fibers and dyes, not by the skin. The Colour-Lock Technology surrounds dyes to deposit a maximum amount of them on the hair for longer-lasting results. This product is designed to be used and sold by trained professionals. Purchaser is completely liable for an outcome from the use of this product and will not hold the seller responsible for unwanted results or damage to hair, skin, nails, or health.
