A great alternative to drugstore hair colour kits! This hair colour is effective at covering greys, without the use of all the harsh chemicals and terrible smell of other brands. Before discovering this brand, I was hesitant about colouring my hair too regularly to cover up grays, but now am absolutely more willing to do it. Also, the colour match is perfect! I purchase a 5N brown and it is almost identical to my natural colour - as the colour disappears, it is incredibly difficult to determine what was my natural colour vs. the dye.
