It varies wildly depending on what hair dye you are talking about. Temporary washes out very quick, semi-permanent lasts several weeks, and permanent should be more or less, well, permanent. It will fade and may wash out some and you can remove it with certain products. Permanent dye should not normally wash out fully. It also depends on the brand, some are better than others.

Semi permanent colour will wash out in 6-8 weeks.
Do you mean pastel hair dye? It depends on if you use a permanent dye or a semi-permanent. Semi-permanent hair dyes will wash out and fade over time; permanent hair dyes will stay in the hair until you cut it or dye it another color.
To remove semi-permanent brown dye, you can try using a clarifying shampoo or a color remover specifically designed for semi-permanent dyes. You may also consider seeking professional help from a hair colorist to safely and effectively remove the dye from your hair.
yes, semi-permanent does not have harmful chemicals like permanent dye, I do it all the time.
Not if you use a permanent dye. If you do your hair will grow out and you will see the original colour. Use semi permanent dyes if you want it to wash out.
It can if you have not washed the excess dye out fully, or if your hair is very porous and has trouble retaining color.
Yes
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.
Yes :)
