Howdoyou make your hair lighter using a rinse if you have a dark colored hair?

You can't. For hair of any color to be lightened, pigment has to be removed, and a rinse won't do that, it only deposits pigment temporarily. A de-colorizer, lightener, bleach, or high-lift tint must be used to lighten hair more than a couple of shades, but I wouldn't recommend doing this on your own. EVERYTIME I have a client that attempts home-lightening, the results aren't just bad...they're expensive and bad. It takes a pro to get even coverage and protect the integrity of your hair. Its way more complicated that just spreading some goop through your hair! Seeing a pro can be expensive, but keep in mind that its always cheaper than seeing a pro for a correction!!! PS There's also no temporary way to lighten hair, once the pigment is gone, its gone, and coloring over can be tricky...don't DIY.
