Spa Master Hair Colour Cream - Blue Black + Oxygen - 20 Vol

The **Spa Master Hair Colour Cream - Blue Black + Oxygen - 20 Vol** is a complete home hair coloring kit designed to deliver a deep, intense blue-black shade. This professional-grade cream color is mixed with the included 20-volume oxygen developer to ensure even, long-lasting coverage from root to tip. The formula not only covers gray hair effectively but also conditions your strands, leaving them soft and manageable after use. Ideal for those who want a bold, dark tone without visiting a salon, the cream applies smoothly and stays put without dripping. Typical usage involves mixing equal parts color cream and oxygen, applying to dry hair, processing for 30 to 40 minutes, then rinsing thoroughly. Because the 20-vol developer lifts natural pigments gently, it works well for dark bases while maintaining hair health. Whether you are refreshing your previous color or trying this dramatic shade for the first time, the **Spa Master Hair Colour Cream - Blue Black + Oxygen - 20 Vol** gives you reliable results at home. Always perform a patch test 48 hours before application to check for any sensitivity.
