"They" say not to color your hair yourself twice - once it has been dyed, go to a professional.
Then again, "they" may be the professionals looking for your business... But it's tricky to play with hair dye too much. You could seriously damage your hair.
You'll never get it back to the natural color by dying it.. Natural literally means 'existing in or derived from nature; not made or caused by humankind'.The best thing to do is wait for the dyed color to fade away.
you're just going to have to wait for it to grow out. assuming that it's darker than your natural color, you could bleach it, then have it dyed back to your natural color, but the process will damage your hair.
Only dye your hair back to it's natural hair color if you're irritated of dying your roots every 3-4 weeks.
In order to go back to a natural color from blue, you will need to bleach and then tone your hair. You need to bleach and then use a color that has a neutral sandy tone to it.
You need to take that problem to a licensed cosmetician who can see what you've done and then fix it. The procedure will probably require bleaching then re-dying.
Grow it out.
Dye it back to your natural color
Being out in the sun all day is whats causing your hair to be lighter. so you could stay out of the sun. or wear a hat. otherwise just dying it will refresh it. but make sure u use a color stay shampoo and conditioner so the color stays next time. :))
No, firstly that would kill your hair, secondly, in order to make darer hair (something not white-blonde) a bright un-natural color, you would have to bleach it first. Then you dye it blue. Otherwise it will be a dark purple color.
If it is temporary hair dye, the color should wash out after awhile. If it is permanent, your natural hair color will come back as the roots grow out, which could take awhile.
Engage the services of a skilled hair colorist who can determine your natural hair color and then adjust your current color. As your natural color grows out, the line between the color and your natural hair won't be as noticeable.
grow out the dyed hair until you see your natural color. wait until it gets long enough, and then cut it.
