Brassy hair – that unwanted orange or yellow tinge that can plague blonde, highlighted, or light brown hair – is a common concern. Many turn to DIY solutions in a desperate attempt to restore their desired color, and baking soda frequently surfaces as a potential remedy. But does baking soda truly remove brassy tones, or is it just another internet myth? Let’s delve into the science, the claims, the potential risks, and explore effective alternatives to achieve your perfect hair color.
Understanding Brassiness: The Root of the Problem
Before we explore baking soda’s potential, it’s crucial to understand why brassiness occurs in the first place. Brassiness is a direct result of the oxidation process, primarily affecting those with lighter hair shades.
When hair is lightened, whether through bleaching or highlighting, the natural pigments are lifted, exposing underlying warm tones. These warm tones, typically red, orange, and yellow, are always present in hair; they are simply more visible when darker pigments are removed.
Exposure to various environmental factors accelerates oxidation, causing these warm tones to become more prominent. These factors include:
- Sun exposure: UV rays damage the hair cuticle and speed up oxidation.
- Hard water: Minerals like calcium and magnesium can deposit on the hair shaft, creating a yellowish or orange cast.
- Chlorine: Swimming pools treated with chlorine can strip away hair’s natural oils and lead to color fading and brassiness.
- Styling products: Some products contain ingredients that can contribute to color buildup and brassiness.
- Heat styling: Frequent use of heat tools like straighteners and curling irons can damage the hair and exacerbate oxidation.
Knowing the culprits behind brassiness is the first step in preventing and treating it effectively.
Baking Soda: The Claimed Brassy Hair Remedy
Baking soda, also known as sodium bicarbonate, is a versatile household staple with various uses, from baking to cleaning. Its alkaline nature is often cited as the reason it’s believed to neutralize brassy tones.
The theory is that baking soda’s high pH (around 9) can help to lift the unwanted yellow or orange pigments from the hair shaft. Supporters of this method suggest creating a paste of baking soda and water, applying it to the hair, and leaving it on for a short period before rinsing.
However, the reality is more complex. While baking soda can have a lightening effect on hair, its ability to specifically target and neutralize brassy tones is debatable and heavily reliant on a range of variables.
The Science Behind Baking Soda and Hair
Baking soda’s alkaline pH does interact with the hair cuticle, causing it to open up. This allows for some level of cleansing and potentially, the removal of some surface buildup or discoloration. However, this opening of the cuticle can also make the hair more porous and vulnerable to damage.
The key question is whether this process effectively removes the warm pigments responsible for brassiness without causing undue harm to the hair.
The Potential Risks of Using Baking Soda on Hair
While some individuals report positive results with baking soda, it’s essential to consider the potential risks before trying this DIY remedy.
- Damage to the Hair Cuticle: Baking soda’s high pH can be harsh on the hair cuticle, leading to dryness, brittleness, and breakage. Overuse can strip the hair of its natural oils, leaving it feeling rough and damaged.
- Scalp Irritation: The alkaline nature of baking soda can also irritate the scalp, especially for those with sensitive skin. It can disrupt the natural pH balance of the scalp, leading to dryness, itching, and flakiness.
- Color Fading: While baking soda might lighten hair slightly, it can also cause overall color fading, especially in color-treated hair. This means that while it might diminish some brassiness, it could also strip away your desired hair color.
- Unpredictable Results: The effectiveness of baking soda for removing brassiness can vary significantly depending on hair type, color, and the severity of the brassiness. Results are often unpredictable and may not be satisfactory.
- Uneven Lightening: It is possible for baking soda to lighten the hair unevenly, resulting in blotchy or patchy color. This is particularly concerning for those seeking consistent and uniform results.
Safer and More Effective Alternatives for Banishing Brassiness
Given the potential risks associated with baking soda, it’s advisable to explore safer and more effective alternatives for neutralizing brassy tones. Several products and techniques are specifically designed to address brassiness without causing significant damage to the hair.
Purple Shampoo and Conditioners: Your Go-To Solution
Purple shampoo and conditioners are formulated with violet pigments that counteract yellow tones in the hair. According to color theory, purple is the opposite of yellow on the color wheel, meaning it can effectively neutralize and cancel out unwanted yellow brassiness.
These products are generally safe for regular use, although it’s essential to follow the instructions carefully to avoid over-toning, which can result in a lavender hue. Look for sulfate-free formulas to minimize dryness.
Blue Shampoo and Conditioners: Tackling Orange Tones

FAQ 1: What exactly is “brassy” hair, and why does it occur?
Brassiness in hair refers to the unwanted warm tones, usually orange or yellow, that appear in lightened or blonde hair. This occurs because the bleaching process lifts the natural pigment from the hair shaft, and often the warm undertones are the last to go. These underlying pigments, combined with environmental factors and mineral buildup from hard water, contribute to the brassy appearance.
The sun’s UV rays can also oxidize the pigments in your hair, leading to further brassiness. Additionally, using heat styling tools without proper protection, swimming in chlorinated water, and even some hair products can exacerbate the problem. Understanding the root cause of brassiness is key to finding the most effective way to combat it and maintain your desired hair color.
FAQ 2: Can baking soda genuinely remove brassiness from hair?
While some claim baking soda can remove brassiness, the evidence is largely anecdotal and not supported by scientific studies. Baking soda has a high pH level, which can lift the hair cuticle and potentially strip away some of the color and mineral buildup contributing to brassiness. However, this effect is often inconsistent and may not significantly neutralize the underlying orange or yellow tones.
Furthermore, using baking soda improperly or too frequently can be damaging to the hair. The high pH can disrupt the hair’s natural pH balance, leading to dryness, frizz, and even breakage. Therefore, relying solely on baking soda to remove brassiness is not recommended as a long-term or reliable solution.
FAQ 3: What are the potential risks of using baking soda on your hair?
The primary risk associated with using baking soda on hair is its high pH level. Human hair has a natural pH of around 4.5 to 5.5, and baking soda has a pH of around 9. This significant difference can disrupt the hair’s natural balance, causing the cuticle to open excessively.
This opening of the cuticle can lead to moisture loss, resulting in dry, brittle, and damaged hair. Repeated use of baking soda can also strip the hair of its natural oils, making it more prone to breakage and split ends. Therefore, it’s crucial to weigh the potential risks against the limited benefits before using baking soda on your hair.
FAQ 4: Are there gentler, more effective alternatives to baking soda for removing brassiness?
Yes, several gentler and more effective alternatives are available for removing brassiness. Purple shampoos and conditioners are specifically formulated with violet pigments to neutralize yellow tones in blonde and lightened hair. These products are designed to be less harsh than baking soda and are generally safer for regular use.
Toning glosses and professional color treatments are also excellent options for correcting brassiness. These treatments are formulated to deposit specific pigments into the hair, effectively neutralizing unwanted warm tones and restoring your desired color. Consulting with a professional colorist can provide personalized recommendations and ensure optimal results without damaging your hair.
FAQ 5: How often can I safely use purple shampoo to combat brassiness?
The frequency of using purple shampoo depends on your hair type, the severity of the brassiness, and the specific product instructions. Generally, it’s recommended to use purple shampoo once or twice a week, but some individuals may need to use it more or less frequently. Observing how your hair responds is crucial to determining the optimal usage schedule.
Overusing purple shampoo can lead to a purple or ashy tint, especially on very light or porous hair. If you notice a purple hue, reduce the frequency of use or alternate with a regular shampoo. Always follow the instructions on the product label and consider consulting with a hairstylist for personalized advice.
FAQ 6: What are some preventive measures to avoid brassiness in the first place?
Preventing brassiness is often easier than correcting it. Using a shampoo and conditioner specifically designed for color-treated hair can help protect your hair from fading and maintain its tone. These products are typically sulfate-free and contain ingredients that help seal the hair cuticle.
Protecting your hair from sun exposure is also crucial. Wearing a hat or using a UV protectant spray can minimize damage and prevent oxidation, which contributes to brassiness. Finally, installing a shower filter to remove minerals and chlorine from your water can significantly reduce mineral buildup and help maintain your hair’s color and health.
FAQ 7: Can baking soda be used as part of a clarifying hair treatment, and if so, how?
While baking soda is not recommended for removing brassiness, it can be used as part of a clarifying hair treatment, but with caution. A very diluted solution of baking soda (e.g., 1 tablespoon in a cup of water) can help remove product buildup and excess oil, but it should be used sparingly and not too frequently.
If you choose to use baking soda for clarifying, ensure you follow up with a deep conditioning treatment to restore moisture to your hair. Due to its potential to strip the hair, it’s crucial to use it infrequently (e.g., once a month at most) and only when necessary. Alternatives like clarifying shampoos are generally gentler and more suitable for regular use.
