Why Do You Get Yellow Hair After Bleaching?
Most people can’t get platinum blonde hair just by bleaching or using high-lift dyes. This is because in order to reach platinum all pigments need to be removed from hair. Bleach removes pigments from hair, but at the same time it weakens it so reaching white from dark hair is often too risky. As the bleaching process goes, hair turns several degrees of orange and, after a while, yellow, pale yellow and almost white. If your hair is naturally brown or black, the red and dark pigments in the hair are almost impossible to eliminate just using bleach, and you will end up with brassy, yellow and gold tones in your hair, or with very damaged hair.
Depending on the porosity of your hair and the strength of the bleach used, this can be an overall yellowing or restricted to some areas of your head. It is important to be careful not to over-bleach your hair to try and get rid of the yellow because you may end up with a chemical haircut instead of glossy platinum locks. So it’s better to try alternatives to bleaching first, to see if you can fix the yellow without damaging your hair.
Even if you have your hair done at the hairdresser, yellow tones can appear after a few washes as the toner used to remove the unwanted yellow tones fades away.
What Is a Toner And What Does It Do?
A toner, also called a gloss, is a product designed to remove unwanted colours in your hair, fill in areas with excess porosity and give your hair a glossy finish. This of it as a topcoat for your hair. After bleach lifts the colour, a toner will fix unwanted brassy or red undertones and give you the perfect ashy or platinum colour you were after. This is known as Two-process colour. A toner can be a permanent or semi-permanent colour which has the right undertones to cancel the yellow tones in your hair. However, after bleach semi-permanent colours are preferable because they are less damaging to the hair.
Depending on which colours you want to cancel, you can use different toners and here is when it gets fun: to cancel reddish tones you would go for a green colour, whereas yellow tones require violet and brassy tones are cancelled by green and blue tones. However, be careful not to overdo it or you may end up with green hair! If you are trying to figure out how to fix orange hair, a greenish toner will be the solution.
A toner is not always necessary: if you have naturally blonde hair, a high-lift permanent hair colour in a platinum shade may be all that you need, without the use of bleach. However, if you have dark hair, bleach will pre-lighten the hair to a degree that applying permanent hair colour in a platinum / ashy shade will create the desired results. Semi-permanent toners generally wash out from hair after 2 to 8 weeks, depending on how often you wash your hair.
Can You Do At-Home Toning?
There are products sold in supermarkets and beauty stores that can work as a toner, as they deposit colour on your hair which cancels the yellow and brassy tones. You can also use a permanent or semi-permanent hair dye but they sometimes have unexpected results as the undertones aren’t clear and you can end up overcorrecting with unwanted blue or green tones in your hair. This can happen if you are learning how to fix orange hair, and you choose a toner that is too green for the amount of orange in your hair.
Hair that has been bleached is more porous than usual, which means even a semi-permanent hair colour (no ammonia hair colours) can take longer to wash out or even not wash out at all. For this reason, it is important to be aware of hair color levels and dye codes so you can pick a dye that fills the color in without adding unwanted overtones or making your hair too dark.
Colour Depositing Shampoos
A safer alternative to fix yellow tones after bleaching is using colour correcting shampoos and conditioners. For example, Redken Blonde Idol Custom Tone for Cool or Platinum Blondes deposits variable amounts of purple in your hair depending on how long it was since you coloured it, keeping brassiness away. Other “Silver” shampoos and conditioners are designed to be used once a week or even every day, but pay close attention to the usage instructions unless you want to end up with bright purple hair.
