The best way to neutralize your orange hair is by using toner, while you can also opt for at-home solutions. There are also a number of proven products in the market that can help you colour correct your brassy hair quite effectively.

What is Brassy Hair

Precisely, brassy is the salon term for the pesky warm tones that often show up after lightening or highlighting the naturally dark hair.

When you bleach your hair to light brown or colour it blonde or platinum, you oxidize its natural pigment in order to make room for the new ones. Doing this can lead to the over-abundance of warmth in the hair if no proper care is taken afterwards. Consequently, the ugly brassy strands become remarkably visible.

Brassiness is, indeed, the biggest enemy of any hair colour treatment. However, it is essential to differentiate this from the warm hues to colour correct your locks. Typically, the mid-section and the ends of your hair shafts get warmed up by the sunlight while the areas near the roots remain unaffected.

So, when the warmer tones are evident at the roots of the hair where cooler and lighter tones are expected, this means that it is brassy.

Why Does Hair Turn Brassy After Dying?

Natural hair gets its colour from its underlying pigment called melanin. The level of melanin determines how hard the bleach needs to work in order to dilute it, in the process, and remove the natural warmth of the hair. The deeper the melanin, the harder it is to lighten your hair colour. So, bleach is used to take the melanin off the brown-black hair in order to lighten it.

When lightening dark hair, some colour treatments may comprise bleaching as the mandatory initial step. Usually, a mixture of ammonia and peroxide is used as a bleaching agent.

The hair is soaked and left for it to oxidize the strands, this is so that the dark colour is lifted effectively and the bleached hair gets to the right shade. It then results in a colour imbalance in the hair, as the warm undertones do not get bleached out fully and, therefore, reveal themselves sooner or later. In turn, this can cause the hair to turn brassy.

Exploring the international colour chart will help you know more about the undertones of different types of natural hair and the shades that they are likely to end up as after getting dyed.

How to Prevent Your Dyed Hair from Getting Brassy

Bleached hair tends to get brassy with time. Nevertheless, it is much easier to take preventive measures rather than scrambling to figure out how to get rid of that brass. Furthermore, there are ways to get back to the cooler tones back into your hair.

So, here is what you can do to avoid it.

Choose the Right Shade

Skip warmer shades of lighter colours and go for ones that have a perfect balance of cooler tones. Due to the presence of larger molecules of pigment, they counteract brassiness and stay in place for long.

Apply Colour Strategically

Minimise the chances of turning yourself into an orange-head by being strategic with the application technique. Choosing highlights-lowlights (individual strands) is always better than all-over colouring (single process) for this purpose.

Use a Shower Filter

Do not let hard water turn your mane dry and brassy by depositing colour-tainting minerals (iron, chlorine, etc.) onto it. Make use of a shower filter to prevent such build-ups.

Steer Clear of Sunlight

When exposed to direct sunlight and air, freshly bleached hair can get warmed and oxidized naturally, thereby revealing the undertones. Hence, resisting the urge of soaking up sun rays as much as possible!

Tip: Ensure that your hair has reached the right level of lightness (light ginger colour) so that your toner gives you the best possible outcomes in terms of fixing the orange undertone.

Application of the Toner

Once you find the right toner for your hair, mix it with a volume of 10 or 20 developers (peroxide) in a plastic bowl.

Blend well and apply the concoction to the orange patches of your hair by using an applicator brush.

Leave it for 45 minutes and then, rinse with a sulphate-free toning shampoo.
