rich color, lasts long
I have used this, and other Naturtint colors, for several years. Right after coloring the color seems a bit heavy and dark, but within a few washes it livens up, with a faint honey highlight effect (I guess, due to several gray strands), which is rich a beautiful. Color lasts over two months. I take care to protect from sun light (wearing a hat when outdoors), and swimming pool chlorine (saturating with hair conditioner before entering the pool).
BTW- my hair is short, and one package has enough products for two coloring sessions.
