How can I dye my medium ash blonde hair to warm golden blonde?

Go buy some hair dye. You can buy a temporary so if you don’t like the color you can just wash it out. Look for neutral or warm tones.

“Dye” means you add color, and that necessarily means the color gets darker. Removing color is “bleach”, and that is somewhat unpredictable, sometimes giving green or grey or orange results. You want to go from one shade of blond to another shade of blond. I am pretty sure you will need professional help for that.

I have used Clairol Natural Instincts ” Sunflower” shade for years and it is exactly what you want. A warm, medium, golden blonde. I have not colored my hair the last 2 years now, letting it grow out again, and my naturally blonde hair is a little ashey now too but still has a lot of natural highlights. I will probably go back to this product eventually.

It is a semi-permanent color that gradually fades after about 24 shampoos, or 8 weeks in my experience. No bleach, no harsh ingredients and looks very natural. That would be my suggestion. Good luck!

I think you should go to a professional also. You probably should do highlights using bleach to highlight strands of your hair to make it look natural and “sun kissed”.

@Coloma Hey, Yes that color is gorgeous I like it I might buy it and apply, I do have shoulder past length hair but I dont have much hair just normal ammout, I might need 2 bottles right?

@cecilia09 No, one bottle should be plenty.
My hair is a little longer than shoulder length but, I used one bottle forever when it was quite a bit longer, like back of your bra length. Just apply it well all over your head then massage it in really thoroughly, then squish your hair up into a ball on the top of your head and put a plastic bag over it for the time. I also left it on for about 30 minutes but follow the directions the fist time.

You really can’t over process it like you could with bleach, the activation time fizzles out anyway after about 25–30 minutes.
It’s a really nice color, I think you’ll like it and it is not harsh on your hair at all. You can also add a few highlights after if you want.
Report back when/if you do it.

Have it weaved by a professional
