How long does it take for demi permanent hair color to wash out?

I was thinking of using RAW Deep Purple Demi-permanent hair color to dye my hair without having the commitment of permanent hair dye. However, I heard that it stains the hair. If I change my mind and want to go back to my natural hair color, how long will it take to go back or how should I go about to get the natural color back? Also, if you have any suggestions on other purple demi-permanent hair colors that don't stain as badly please tell!How long does it take for demi permanent hair color to wash out?
What colour is your hair now? If it's dark, then you will just get subtle purple tones which will gradually wash out over a month or so. If your hair is blonde, then it might last longer, but will still fade to probably a lilac kind of colour.


Semi-permanent dyes only penetrate the hair shaft by a small amount. So they wash out gradually and don't leave visible roots. If you wanted to remove the dye quicker, you could just use another semi permanent dye close to your natural shade, or shampoo your hair with a cheap shampoo which will tend to strip the colour out (use a heavy duty conditioner afterwards if you do that)How long does it take for demi permanent hair color to wash out?
I am a stylist. If you are a blonde, or light brunette tones of the purple will stay indefinitely. If your hair is dark brown demi will last 5 to 8 weeks depending on the porosity of your hair. If you are a lighter hair color and want to eventually go back to your natural color you could be looking at a big expense. Corrective color would be necessary to fix your hair. There are some other options. You could do streaks or even extensions of the purple. If you have them put in by a stylist this could be affordable. I would suggest doing a peek-a-boo effect with the purple, big chunky sections that peek out underneath or on one side of you hair. That is very hot right now, good luck!
I had a wash out dye of dark blue for my hair..and it felt like it was in my hair forever. After the tenth or eleventh wash I got my hair color back...So it all depends on how often you wash it with in a 1-2 month period.
I think you mean semi-permanent and it depends on how much you're particular hair strand cuticle absorbs the color. Don't think I would mess with it. See a proffesional colorist and ask.
it stands on the package, honey. read it there.
It takes a few weeks... about 6-8.
