The choice is yours but it is not recommended. Your hair will become over processed from the chemicals and you can cause severe breakage.
As many as you want. However you are just ruining your hair. Unless you are using a non- damaging color.
One method would be to use pet waste cleaner.
Only if you use really crappy and cheap hair color. I get mine done at a salon and it doesnt fade at all. The only color that won't wash out is a permanent color. Every other one will, especially temporary color, and that is what it sounds like you have because of it being on the towel. Temporary color only lasts one wash and is meant to come out then. You will need to rinse your hair better so that there is no color on the towel. Also if you want to have the color last longer in your hair get a semi permanent color; it lasts 6-8 washes.
The permanent color should cover the semi permanent one, if dark enough. But, yes, eventually the semi permanent color will fade away.
One can find a hair color chart online from the Hair Color Code website. One can also find a hair color chart from Clairol or Garnier's websites, as well.
It won't remove it - the semi will need to wash out or fade over time. It will cover over it, but the end result may not be the one on the box as you will not be dying natural hair.
Yes, you can get spray on hair color that will come out after one wash.
Scandinavian Blonde Is One of My Favorite Hair Colors, And Irish Red Is One of My Sister, Tabitha's Favorite Hair Colors.
Use a color protection shampoo and conditioner as well as a Moisture Balance shampoo and conditioner. USE CONDITIONER. (Twice a week try to use a deep moisturixing leave in treatment to keep your hair in good shape.) You will want to alternate between the two to keep the color and keep your hair healthy.
I think it is, or was...one week he came on with short hair then the next week he had the dreadlocks back
A rinse generally lasts for a few washes, depending on the type of rinse used and the hair's porosity. It may start to fade with each wash, especially if using a temporary or semi-permanent rinse. For more lasting results, consider using a permanent hair color.
