The commonly used hair color bottle is a two-part bottle that squirts color using gravity. This requires shaking color down towards the nozzle, much as we do with a ketchup bottle. Color comes out in uneven and uncontrolled spurts. In order for the common bottle to work, the head and body must be positioned underneath the bottle which has to stay upside-down. This position limits visibility which is important when applying dye. The Hummingbird was designed by a hairdresser and is all about precision, results and experience. Composed of precisely engineered parts, most importantly, a double-valved system that allows color to be applied in an upright position so you can see what you're doing, while providing ultimate control of the flow of color. The beak takes precise partings and spreads the color. Precisely applied hair color means healthier hair, superior results and a less messy, premium experience. The Hummingbird is a patented 3 in 1 tool that can be used again and again!
