John Frieda Brilliant Brunette Luminous Glaze, Colour Enhancing Shine Glaze, Designed to Fill Damaged Areas for Smooth, Glossy Brown Hair Color, 6.5 fl oz

First of all this stains your hands immediately so I have started using gloves. That staining is inconvenient but is a testament to how well this adheres to your hair too. It covers grey! I have been blending my grey with a demi permanent (natural instincts) to avoid damage but that still uses some lift to deposit the color. This glaze just deposits. No lift. It basically stains your hair but it's a nice warm brown that really comes out well for me. I couldn't believe how well it doesn't far as grey coverage. I haven't had to dye my hair since I started using this and I'm probably 25% grey under it. I use it every other day. I mainly concentrate on my roots and then pull through my length and that works for me.
