If you want to look like the pics you posted, this is what will happen:
The stylist will pre lighten your hair, either with a high volumed developer and colour or bleach, depending on whether you have 'virgin' hair or coloured hair.
Then he will add foil highlights using bleach to achieve the really blond streaks.
He will most likely then have to tone the blond and overall colour. This means using a violet based colour to "cut" out the gold tones.
If after a couple of weeks of colouring, you use a purple based shampoo, that will help to keep the brassiness out of your hair.
Going back to a darker colour, does take a few steps, such as "filling" the light pieces first before putting the dark colour over them.
If you have a good stylist, then you should have no problems! You only live once, so go for it Ivy!
