Really lovely product to use. No hash smells, only lovely, relaxing smells.
Colour is fantastic. I am a brunette, and this dye gives copper colours to all my sun lightened and grey bits and the ends.
I even had someone ask if I had 'streaks' put in my hair from a salon. (I haven't been to a salon in about 2yrs.)
Colour lasts about the same amount of time on greys as Henna does.
I choose to use this product because of the smell & time factors, even though it costs more.
