Have you recently dyed your hair only to end up with a new warmer tone in the weeks following your visit to the salon? This issue is known as brassy hair and it can occur with many color transformations, but is most common when going from dark hair to a lighter shade such as platinum or blonde. When brassiness occurs, you’ll notice cool tones turning into warmer hues such as yellow, orange, or red.  

Whether you want to prevent brassy hair or get rid of it, we’re here to help. Find out everything you need to know about brassy hair including what it is, what causes it, and how to prevent it from ruining your look.

What is brassy hair?

Brassy hair is the appearance of unwanted warm tones in color-treated hair. It’s most common in dark hair that’s been dyed to a brighter shade like blonde, silver, or gray. Brassiness usually starts at the roots, and appears as warm yellow, orange, and red tones. 

Why is brassy hair bad?

Many people see brassy hair as a problem because it causes undesired tones that change the look of your hair. This occurs because your natural hair undertones return and mix with the dye. For example, someone who is originally brunette but has gone platinum may find that their hair will turn orange. Even in the early stages of brassy hair, having uneven tones at the roots can affect the look of the hair.

What causes brassy hair?

Did you know each strand of hair has three layers? That’s right. he cuticle, the cortex, and the medulla. Your natural hair color comes from pigments in the middle layer (the cortex) and these can become more visible through long-term sun exposure or chemically lightening them.

Lightening your hair through a dyeing process strips the middle layer of your natural color pigments, wiping the slate clean to make room for new pigments deposited from the dye you’re using.

When the lightening process doesn’t get rid of all the underlying pigments you may end up with brassy hair that appears orange, yellow or a warmer color than intended. This may be noticeable immediately after dyeing, but in some cases the results may appear in the coming weeks as your natural undertones return and mix with the dye.

How to prevent brassy hair

Rather than trying to fix or get rid of brassy hair after dyeing, check out these tips to prevent it:

Use Purple Shampoo and Purple Mask

For anyone with lightened hair, purple products are a must. Products like our Purple Shampoo and Purple Mask help prevent brassiness by counteracting warm tones before they ruin your look. They work based on the science of color theory, which states that colors on opposite spectrums of the color wheel will cancel each other out. On the color wheel, violet is opposite of warm colors like yellow, orange, and red — meaning violet shades will neutralize warm colors. These products are formulated with violet pigment and deposit a small amount into your hair to counteract brassy tones. As an added bonus, they also help restore moisture to nourish strands so they can stay soft and shiny.

Use a color neutralizing toner

During the bleaching or lifting process, use a color-neutralizing toner to remove any remaining natural hair pigment that can lead to discoloration or brassiness. As an added bonus, a toner also helps to lock in the new color and reduce fading.. Use a toner every six to eight weeks to help keep your colored hair fresh and brass-free.

Minimize washes with dry shampoo

Try to minimize washing to slow the color-fading process/ . Instead, use a purple-hued dry shampoo such as our Dry Shampoo Light to brighten blondes and counteract brassy hues while cleansing hair.

Wash hair with cool water

When your hair is due for a wash, keep the water temperature low. Hot water opens the hair’s cuticle which can result in color fading and brassiness. Instead, try washing your hair with cool water which seals the cuticle, allowing it to retain moisture for added smoothness and shine. To ensure colored hair gets enough moisture, use our Hydrating Shampoo and Hydrating Conditioner to gently cleanse and nourish hair then follow up with our elasticity-enhancing Leave-In Mist before styling.

Avoid excessive sun exposure

Long term exposure to direct sunlight can dry hair out and speed up the fading process. In addition to damaging UV rays, being outside for long stretches of time exacerbates the oxidation of your hair which damages the outer layer of the hair shaft and can lead to brassiness. To prevent this, wear a hat when you go outdoors or use UV-protectant hair products.

Remove product build-up and repair hair before lightening

Before your next color treatment, make sure your hair is in good condition to go through the lightening process. After all, you don’t want product build-up and existing damage to interfere with your color transformation. To give your hair a clean slate, start by using a purifying shampoo such as the Reset Clarifying Shampoo. Follow this by using our Reset Repairing Mask to nourish hair from the inside out, then use the Reset Sealing Mist to complete your Reset routine.
