Red hair has a lot more red pigment than ashier, colder tones. And so, when bleached it tends to turn an unflattering shade of orange rather than yellow. Damage should be your number 1 concern when going from red to blonde hair at home.
What happens when you put bleach on red?
The chlorine element in a classic chlorine-based bleach oxidizes the iron from the porcelain. Oxidized iron is rust, hence the rusty red color. Make sure your bathroom is well-ventilated; you don’t want to breathe in too much chlorine gas!
How do I go from dyed red hair to blonde?
If you want to take your hair from red to blonde at home, you’ll need to strip out any dye still in your hair and then bleach it. Once it’s bleached – which might take several rounds of bleaching – use a toner to elevate your hair from brassy to blonde!
How can I darken my bright red hair?
When dyeing your hair darker, you can dye over the existing color using an at-home dyeing kit. Dye your hair a dark shade of brown or black so the red hues do not show through the hair color. Shampoo your hair in warm water to remove as much of the original bright red color as possible.
