Does Baking Soda Remove Hair Color? A Deep Dive
Baking soda can help to fade hair color, but it’s not a guaranteed or predictable color remover on its own. The effectiveness depends on the hair color type, hair porosity, and other ingredients used in conjunction with it.
The Science Behind Baking Soda and Hair Color
Baking soda, also known as sodium bicarbonate, is a mildly alkaline substance with abrasive properties. This alkalinity is what allows it to potentially lift color molecules from the hair shaft. Hair dyes, both permanent and semi-permanent, work by depositing color into the hair’s cuticle or cortex. Baking soda, due to its alkalinity, can slightly swell the hair shaft and disrupt these color molecules, causing them to release and wash away. However, the effect is typically much milder than professional color removers or bleaches.
Factors Influencing Baking Soda’s Effectiveness
Several factors influence whether baking soda will successfully fade hair color. Understanding these variables is crucial before attempting this method.
Hair Porosity: High porosity hair, meaning hair with more open cuticles, tends to release color faster. Baking soda will likely be more effective on highly porous hair compared to hair with tightly closed cuticles (low porosity).
Type of Hair Dye: Semi-permanent and demi-permanent dyes are more easily lifted than permanent dyes. Permanent dyes penetrate deeper into the hair shaft and are therefore more resistant to fading with baking soda. Direct dyes (vibrant colors like pink or blue) can sometimes be removed more easily, but results vary greatly.
Color Depth: Darker colors like black or dark brown require more significant lifting to show a noticeable difference. Baking soda may only cause a slight shift in tone rather than complete removal.
Frequency of Use: Multiple applications of baking soda mixtures may be needed to achieve desired results, but frequent use can also lead to dryness and damage.
Baking Soda Mixtures for Hair Color Removal
Baking soda is typically mixed with other ingredients to enhance its color-fading capabilities. Common combinations include:
- Baking Soda and Shampoo: A simple mixture of equal parts baking soda and clarifying shampoo can create a mild stripping effect.
- Baking Soda and Hydrogen Peroxide: This is a stronger combination, and caution is advised. Hydrogen peroxide is a bleaching agent, so this mixture can lighten the natural hair color as well. Use with extreme care and strand test first.
- Baking Soda and Dish Soap: While effective, dish soap is very harsh and drying. It’s not recommended due to the potential for significant damage.
- Baking Soda and Anti-Dandruff Shampoo: Some anti-dandruff shampoos contain ingredients that help to lift color, making this a slightly more effective combination than baking soda and regular shampoo.
The Process: A Step-by-Step Guide
If you choose to try baking soda to remove hair color, follow these steps:
- Perform a Strand Test: Before applying the mixture to your entire head, test it on a small, inconspicuous section of hair to assess its effectiveness and potential for damage.
- Mix the Ingredients: Combine baking soda with your chosen ingredient (shampoo, hydrogen peroxide, etc.) in a non-metallic bowl.
- Apply the Mixture: Apply the mixture evenly to damp hair, focusing on the areas where you want to remove the color.
- Process the Hair: Cover your hair with a shower cap and allow the mixture to sit for 15-30 minutes, checking periodically.
- Rinse Thoroughly: Rinse the hair thoroughly with lukewarm water until all traces of the mixture are gone.
- Deep Condition: Baking soda can be drying, so follow with a deep conditioning treatment to replenish moisture.
Potential Risks and Side Effects
While baking soda is generally considered a safe household item, it can cause adverse effects when used on hair:
- Dryness: Baking soda can strip the hair of its natural oils, leading to dryness, brittleness, and frizz.
- Damage: Overuse or improper application can damage the hair cuticle, making it prone to breakage and split ends.
- Scalp Irritation: Some individuals may experience scalp irritation or sensitivity to baking soda.
- Uneven Results: Color removal may not be uniform, resulting in patchy or uneven tones.
Alternatives to Baking Soda
If you’re concerned about the potential risks of using baking soda, consider these alternative methods for removing hair color:
- Color Remover Products: These products are specifically formulated to remove artificial hair color without causing as much damage as bleach.
- Professional Hair Color Correction: A trained hairstylist can assess your hair and use professional techniques to safely and effectively remove the unwanted color.
- Color Fading Shampoos: Certain shampoos are designed to gradually fade hair color with each wash. These are gentler than baking soda but also less effective for dramatic color changes.
Common Mistakes to Avoid
Avoid these common mistakes when using baking soda to remove hair color:
- Using Too Much Baking Soda: Using an excessive amount of baking soda can increase the risk of dryness and damage.
- Leaving the Mixture on Too Long: Over-processing the hair can lead to breakage and split ends.
- Using Hot Water: Hot water can further dry out the hair, exacerbating the drying effects of baking soda.
- Skipping the Deep Conditioner: Failing to deep condition after using baking soda can leave the hair dry, brittle, and prone to damage.

Frequently Asked Questions (FAQs)
Will baking soda remove black hair dye?
Baking soda is unlikely to completely remove black hair dye. It may help to fade the color slightly, but professional color removal is usually necessary to achieve significant lightening.
Can I use baking soda on bleached hair?
It’s not recommended to use baking soda on bleached hair. Bleached hair is already damaged and porous, and baking soda can further dry it out and cause breakage.
How often can I use baking soda to remove hair color?
It’s best to limit baking soda treatments to once or twice a month at most, to minimize the risk of dryness and damage. Always deep condition afterward.
Will baking soda remove red hair dye?
Red hair dye is notorious for being difficult to remove. Baking soda might help to fade the color slightly, but results are unpredictable.
Does baking soda lighten natural hair color?
Baking soda itself is unlikely to lighten natural hair color significantly. However, when combined with hydrogen peroxide, it can have a slight lightening effect, similar to a weak bleach.
Can I use baking soda to remove toner?
Baking soda can be effective at removing toner, especially if the toner is freshly applied. The alkalinity of baking soda can help to lift the toner pigments from the hair.
What is the best baking soda mixture for removing hair color?
There is no single “best” mixture. A common and relatively gentle option is equal parts baking soda and clarifying shampoo. For more stubborn colors, a mixture of baking soda and a small amount of hydrogen peroxide might be considered, but with extreme caution.
How long should I leave baking soda on my hair to remove color?
Generally, 15-30 minutes is a safe processing time. Continuously monitor your hair during the processing time and rinse immediately if you notice any signs of damage or irritation.
Does baking soda damage hair?
Baking soda can damage hair if used improperly or too frequently. It can cause dryness, brittleness, and breakage. Proper hydration through deep conditioning is essential after using baking soda.
Can baking soda remove semi-permanent hair dye?
Baking soda is more likely to be effective at removing semi-permanent hair dye compared to permanent dye, as semi-permanent dyes don’t penetrate the hair shaft as deeply.
What should I do if baking soda dries out my hair?
If baking soda dries out your hair, immediately apply a deep conditioning treatment. Look for products containing moisturizing ingredients like shea butter, coconut oil, or argan oil. You can also try a hair mask or hot oil treatment to replenish moisture.
Is it better to use baking soda or a color remover?
A color remover is generally a better option than baking soda for removing hair color, as it’s specifically formulated for this purpose and typically causes less damage. Baking soda is a gentler, but often less effective, alternative.
