How are you using red gold corrector More? How many drops, and you can add it to shampoo or conditioner?
I'm dying my hair a normal promoter (20) and goes blonde. Normally, I see red when I use copper and gold dyes. I was given this at Supply beauty, but do not know how to use it and it does not come with directions.
10 drops per ounce of each color you use. Ex: If you use two ounces of colors you can use 20 drops of red gold corrector. I work at Sally Beauty Supply and I use on my hair. And yes you can add your shampoo, just use a few drops.
