It depends on the color of your own hair. I have light brown hair that turns almost blond in the summer. Once I tried black color shampoo in wash out color. It took close to three months washing it everyday.How long does it take for a black hair color rinse to rinse out.?
usually it should take up to 3 to 6 weeks but thats if your heair is a naturally dark colour. If you have a blonde hair colour its unlikly that its going to fully wash out to your old colour and thats the same with reddish hair.
