How to reduce red hair colour with ash

Updated February 21, 2017

Permanent and semi-permanent hair colour comes in literally thousands of different shades. Warmly toned hair dye, which includes auburn, golden and red, makes up just a fraction of the shades available. Reddish tones are best for people with warm skin tones, who sometimes have naturally reddish or golden hair. To reduce these red tones, you need something to counteract the warm shade and neutralise it. Another tone available is ash, which is a cool-toned shade. Use ash tone hair colour to get rid of red tones in your hair, whether it be natural or dyed.

Choose a semi-permanent ash hair colour that is a similar tone to your natural or pre-dyed hair colour. You can also select an ash colour that is darker or slightly lighter than your hair.

Mix the hair colour ingredients together according to the manufacturer's directions.

Apply the hair colour all over your hair, which should be unwashed and free of styling product, starting at the ends and working towards the roots. Make sure all of your strands are completely saturated.

Pile your hair on top of your head. If necessary, clip it loosely into place with a large hair clip. Allow the dye to process for the recommended amount of time.

Rinse the colour out of your hair with cool water until the water runs clear. Squeeze the excess water out of your hair and apply colour-safe conditioner from root to tip. Let the conditioner sit for about two minutes.

Rinse the conditioner out of your hair with cool water. Towel-dry your hair gently; then style as usual.


Semi-permanent colour generally washes out within 28 shampoos and typically contains no ammonia, which is damaging to hair. The dye fades naturally, without leaving grown-out roots. Use an ash light-blond colour after bleaching your hair blond. Bleach often leaves hair looking brassy or yellowish. The ash tones in the hair colour will neutralise these brassy tones.
