Either are great but make sure you let it sit for at least half an hour and use water as hot as you can bear it as that opens your cuticles :)
Yes, unless Head & Shoulders makes a sulfate-free shampoo or a color-safe shampoo, it will most definitely strip hair color.
There is permanent hair color and semi-permanent hair color. _____________ Demi permanent and temporary are also known as non permanent hair color.
Yes, it's fine to apply permanent color over semi permanent.
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.

Yes, you can apply permanent hair color on top of semi-permanent hair color. Make sure that you do a deep conditioning treatment or hair masque before and after you color your hair.
Of course you can. Semi permanent dye simply adds color to your hair. A permanent will actually cause your natural color to change. But remember this... color doesn't lift color. Therefore if your semi permanent hair color is darker than the permanent color you are going for---- it isn't going to work. You need to use a color remover before hand. And color removers are REALLY damaging to hair.
If the scalp is in good condition and was not irritated by the semi permanent color, it's OK to apply permanent color within 24 hours after initial color service.
Yes, demi permanent hair color can be applied over any type of color. It will refresh the original color very nicely.
