I few years ago I used to consistently dye my hair brown, since I have dark blonde (with bleached highlights) hair I found that brown would never really stay vibrant enough on my hair, especially on the parts which were previously bleached, these sections would definitely wash out a lot quicker. I used to use this product once every week or two to keep my hair a nice vibrant brown tone, it worked very well. Definitely helps extend the life of your colour & a lot better for your hair that constantly dying it

Not very effective. I have dark strawberry blonde hair, and used the Chocolate Kiss color. It barely made a difference in my hair, and i used alot. It did make my hair a little shinier, though. Rubs off on pillows overnight... It is inefficient, as it washes out, but according to the website, it is intended to cover gray hairs. If you are going to use it for that purpose, something that lasts more than a day would be better. Also extremely runny and messy, but doesn't stain hands.
