demi-permanent colors last about 30 washes...so I guess if you didn't like it you could just take a really long shower.
Sure - theatrical companies use huge amounts of it. A supplier of theatrical supplies will have it - you may need to do a search.
i think so
yer, its called a rinse
6-20 washes
It depends on the dye you used: if it was temporary when you shampoo your hair the dye will wash out straight away. If it is semi permanent it was last 6-8 washes, if it is a quasi permanent you get 12-24 washes and if it is permanent it won't fade. So depending on how long your dye will last you can wash your hair when you like.
Well its not permanent, so it should wash out in a few washes. Or what ever it says on the hair dye box.
Any dye that does not say PERMANENT will wash out after a certain number of washings.
Yes, you can use Jello mix as temporary hair dye. It will last 7-10 washes.
Powered Kool aid works well and washes out easy. The only default with that is it stains hands and towels easily. Another possibility can be Halloween hair dye typically at your Halloween stores like spirit or party city. They sell color in a can that easily washes out.
Semi permanent colour will wash out in 6-8 weeks.
Try Kool-Aid. It washes out after one use so you can use many different colors.
Semi permenant hair dye lasts up to 24 washes/shampoos :}
from my experience, it wouldn't it would have the colour left over even after the washes, ive done this numerous of times and my blonde went back crappy, so if you want your blonde hair to come back, i wouldn't recommend it.
