Hello.
I have my hair colored to a light yellowish blonde with a bit of orange in it.
My natural hair color is dark blonde, the new hair color is to bright for me ,
How can I go to a darker blonde? Of course not by myself I'll leave it to the professional, what's the process? Does he need to fill my hair with red first? (my hair is not white blonde) and if so will the color turn out dark brown? Is it possible to get dark blonde after the filler?
And also do I need to wait few weeks after the filler or it is possible in one session?
Will the color look natural?
Thanks :)

First of all your hair shouldn't have any orange in it. Whoever did your color messed it up. It can be fixed but it may end up being a color correction which may take a couple sessions. Hard to say without seeing your hair. You probably have a lot of red tones to your hair and will need an ash tone to counteract the red tones. A color professional will have to see your hair in order to tell you what will need to be done.

No what I meant was that I have a warm tone of blonde not that it's orange not at all...
So about the going darker?

Then I would say they could probably do it in one session. If you are going darker it should be no problem.

Ask your stylist to use a demi permanent color to tone down and darken a little. She knows what she's doing , so don't try this yourself! You can accomplish this in one session and won't do any more damage than is already done with this color
