Brassy hair can be a frustrating and unwanted hair issue that many people experience. It can change the overall look of your hair color and make it seem dull or less vibrant. To understand this problem better, we turned to experts in the field of hair coloring and hair care to learn about the causes of brassy hair and the most effective ways to fix it.

What is Brassy Hair?

Brassy hair refers to a hair color that has an unwanted warm, orange – or yellow – toned appearance. This is especially noticeable in hair that has been colored, particularly in blondes and lighter shades of brunette. The brassiness can make the hair look unnatural, as if the color has gone awry. It occurs when certain pigments become more prominent than desired in the hair shaft.

Causes of Brassy Hair

Hair Coloring and Chemical Processes

• One of the primary causes of brassy hair is the result of hair coloring. When you bleach your hair, the process removes the natural melanin pigments. However, if the bleaching process isn’t controlled properly, it can leave behind unwanted warm – toned pigments. These warm pigments are often more resistant to the bleaching agents and can become dominant in the hair color. For example, in the process of going from a darker hair color to a lighter blonde, if the bleach doesn’t fully lift all the pigments evenly, the remaining yellow or orange undertones can cause brassy hair.
• Additionally, some hair dyes, especially those that are not formulated well or are of lower quality, can contribute to brassy tones. They may contain ingredients that interact with the hair’s natural or existing pigments in a way that enhances the warm tones. Chemical treatments like perms or relaxers can also affect the hair’s color and potentially lead to brassiness, as they can alter the hair’s structure and how it holds color.

Sun Exposure

• The sun’s ultraviolet (UV) rays can have a significant impact on hair color. Just like how the sun can fade and change the color of fabrics, it can also affect the pigments in our hair. UV rays can break down the hair’s color molecules, causing them to shift in tone. In the case of lighter hair colors, this often results in the appearance of brassiness. The sun can cause the hair to oxidize, which brings out the warmer undertones that were previously less noticeable. People who spend a lot of time outdoors without protecting their hair are more likely to experience this issue.

Hard Water

• Hard water contains high levels of minerals such as calcium, magnesium, and iron. When you wash your hair with hard water, these minerals can build up on the hair shaft. Over time, this build – up can interact with the hair’s color and cause it to take on a brassy appearance. The minerals can affect the way light reflects off the hair, emphasizing the warm tones. This is particularly common in areas with hard water supplies, and it can be a persistent problem if not addressed.

Product Buildup

• Using a large number of hair products that contain certain ingredients can also lead to brassy hair. Products like some shampoos, conditioners, and styling products may leave behind residues on the hair. These residues can combine with the hair’s natural oils and pigments, altering the color. Some products may also have ingredients that react with the hair’s color molecules over time, contributing to the development of brassiness.

How to Fix Brassy Hair

Purple or Blue Shampoo

• Purple and blue shampoos are highly effective in combating brassy hair. These shampoos work based on the color – correcting principle of the color wheel. Purple is opposite yellow on the color wheel, and blue is opposite orange. Therefore, purple shampoo is ideal for blonde hair with yellow undertones, while blue shampoo is better for hair with orange undertones. When you use these shampoos, the purple or blue pigments in them counteract the warm tones in the hair. You should use them once or twice a week, depending on the severity of the brassy tones. Leave the shampoo on the hair for a few minutes to allow the pigments to work before rinsing thoroughly.

Toners

• Toners are another great option for fixing brassy hair. They are usually applied after bleaching or coloring the hair to neutralize any unwanted warm tones. Professional hair salons often use toners, but there are also at – home toning kits available. Toners contain pigments that are specifically formulated to correct the hair’s color. They can be customized based on the type of brassy tone you have. For example, a toner with a violet base can be used to tone down yellow brassiness in blonde hair. The application process may vary depending on the product, but generally, you apply the toner evenly to the hair and leave it on for a specified amount of time before rinsing.

DIY Natural Remedies

• There are some natural remedies that can help reduce brassy tones. For instance, a mixture of apple cider vinegar and water can be used as a final rinse after shampooing. The acetic acid in apple cider vinegar can help remove product build – up and some of the minerals from hard water, which may be contributing to the brassiness. Another option is using a chamomile tea rinse for blonde hair. Chamomile has natural lightening and toning properties that can help brighten the hair and reduce yellow undertones. Brew a strong chamomile tea, let it cool, and then pour it over your hair as a rinse after shampooing.

Protecting Your Hair from the Sun

• To prevent further sun – induced brassy hair, it’s important to protect your hair when you’re outdoors. You can wear a hat or use hair products that contain UV filters. There are leave – in conditioners and hair sprays specifically designed to protect the hair from the sun’s rays. These products create a barrier that helps prevent the UV – induced oxidation of the hair’s color pigments. Additionally, avoiding prolonged sun exposure during peak hours can also help keep your hair color looking fresh.

Dealing with Hard Water

• If hard water is an issue, you can install a water softener in your home. This will reduce the mineral content of the water you use for washing your hair. Alternatively, you can use a chelating shampoo once a week. Chelating shampoos are designed to bind to the minerals in hard water and remove them from the hair shaft. They can be very effective in preventing the build – up that leads to brassy hair.

In conclusion, understanding the causes of brassy hair is the first step in effectively fixing and preventing it. By using the right products and taking preventive measures, you can maintain the desired hair color and keep your locks looking vibrant and free from unwanted warm tones. Whether you choose professional – grade solutions or prefer to try some natural remedies at home, there are plenty of options available to combat brassy hair.
