For reference my hair is professionally coloured a dark brown/black. I bought this on a rec from a sales person at Trades Secrets when I was looking for shampoo and conditioner that would prolong the vibrancy of my colour. She recommended Colorglow, but the darkest shade they have is either Brown Cool or Brown Warm and nothing for darker shades. I went with Brown Warm. I use this, and the shampoo, 2-3X a week. It smells wonderful. When I first applied this to my hair, I thought for sure it was crap. It's thinner than what I prefer in a conditioner and my hair felt tangled and gnarly as I was rinsing. The conditioner itself is a chocolate brown colour and is supposed to deposit colour on my hair, preventing colour wash out. Well, colour me surprised in the end; once dried, straightened and ironed, my hair looks wonderful and it feels fabulous.
