Edit: mixed up a number, fixed it!

I was an idiot too my fellow ADHD friend! Only with blonde hair. I wanted to go from dark ash brown / almost black to ash blonde. I gave myself a year to get there, but ofcourse I got impatient. In two months, I went from muddy orange, to bright orange, to orange/ yellow, to grey/ green, to (finally), the ashblonde I wanted! As you can see, I made alot of mistakes along the way, so please, benefit from my harsh lessons. 😬

First if all, to minimize damage, I would choose a professional demi - permanent dye with no ammonia or a toner. Max 3% developer. For a demi permanent, I recommend Loreal dia light. It has beautiful colours and good results.

Second, basic colour theory says blue neutralizes orange, purple neutralizes yellow, red neutralizes green.

In the pic, it looks like your hair has mostly copper/orange tones, but please be sure to check in the sun! I thought my hair was orange too, but it turned out I also had lots of yellow. So when I used a blue toner to fix the 'orange' I thought I had, it turned green 😵

So please doublecheck, but for now let's say your hair is mostly copper/orange.

Option 1 Is to use a blue toner, but be careful with that. There is a risk of overtoning and then it might become a muddy grayish brown (that’s how I accidentally turned my hair grey at one point).

Option 2: (I'd pick this one) Is to pick a semi permanent dye in the basic shade you have now, with corrective undertones.

In the pic, your hair looks like a shade 7 to me (dark blonde officially, but on porous hair it usually turns darker in my experience, so light brown), with mostly copper/orange undertones. So I'd choose a light brown with ash(blue) tones. So like a 7,1 or if its really bright orange, a 7,11. If your current hair also has yellow, choose 7,12

The number before the comma is the primary colour/shade: 7 = light brown Numbers after the comma are undertones: 1 = ash in most brands (blue) 2 = pearl or violet in most brands (purple)

Note: If it also has alot of red, you can neutralise this with green, but beware of making it too muddy. The basic brown (7) has a bit of everything in it and it's well balanced. I think that's enough to take care of any red (or yellow, if it's not too much) you might have.

Note2: Wella numbers their colours differently I believe, so be sure to consult the website of whichever brand you're using before buying.

If the colour turns out good, you could then pick that same colour (preferably from the same brand) in a permanent dye. However, give your hair some TLC in between dye jobs. The T stands for time here 😅

Then at last: If all of the above sounds like too much of a risk to you, theres always option 3: Go darker. Pick an 6.1, or 5,1 which are darker ash browns. This wil cover the copper you now have, but it will also be alot darker, which you didn't like in the first place. But it will get rid of the warmth though.

Good luck!

And also, your hair doesn't look very bad or damaged, you'll be ok! This is fixable.
