Is there a way to save my hair or should I just wait?

You could try first washing your hair, and then getting a color that looks dark enough to cover up your copper blonde. Maybe something like medium auburn would look nice. If you’re afraid that it might make your hair look worse, then you should just stick to waiting and using shampoos especially for blondes.

Most likely the reason your hair took the coppery color is because aside from looking at the actualy color you are coloring your hair, you have to look at the base color. Violet, blue, orange, gold, green..your hair will suck up the base and therefore you have to mix and match properly.

My advice for this, is that you go to a hairstylist to fix it. You’ve now crossed the line into the need for a professional.

Please..unless you are coloring your hair jet black or dark brown (which is basically idiot proof), ALWAYS see a professional. It’s worth it and you save your hair a ton of damage.
