What Is Baking Soda?
Baking soda, also known as sodium bicarbonate, is a white, crystalline powder with a naturally high alkaline pH of 9. Originally derived from trona ore deposits formed millions of years ago, this versatile compound has been used for centuries in baking, cleaning, and even personal care routines. In the context of hair care, its alkaline nature can help break down oils and remove product buildup. However, because the natural pH of the scalp is around 5.5, using a product with a pH of 9 can disrupt your hair’s natural balance if not used sparingly.
Claimed Benefits of Using Baking Soda on Hair
Many enthusiasts advocate for hair clarifying with baking soda due to its reported benefits:
• Removes Product Buildup: Baking soda effectively dissolves residual styling products, oils, and pollutants that regular shampoos might not completely eliminate.
• Scalp Exfoliation: As a gentle abrasive, it helps scrub away dead skin cells from the scalp, which can lead to a fresher, cleaner surface.
• Oil Control: Its degreasing property can temporarily absorb excess oils, making it a favored remedy for those with oily hair.
• Detoxifying Hair Rinse: Some users claim it detoxifies hair by removing impurities and environmental pollutants.
Though these benefits sound promising, it’s important to understand that many of the claims are anecdotal and not always supported by robust scientific research.
Potential Risks and Drawbacks
While baking soda hair wash may offer a natural alternative to commercial products, potential risks include:
• Disruption of pH Balance: The scalp’s ideal pH is around 5.5, but baking soda’s alkaline nature (pH 9) may disrupt this balance. This can lead to dryness and may weaken the hair cuticle over time.
• Stripping Natural Oils: Frequent use can remove healthy natural oils, leading to scalp dryness, irritation, and possibly increased hair breakage.
• Scalp Irritation: Sensitive skin and color-treated hair may react adversely, with reports of redness, itching, or flaking after use.
• Hair Damage: Overuse or improper application methods might lead to cuticle damage and decreased tensile strength, making hair prone to breakage.
It’s essential to weigh these risks against the benefits and consider consulting a dermatologist or hair care professional before beginning any DIY hair treatment.
How to Use Baking Soda for Hair
Using baking soda safely for hair care involves following a clear process and limiting frequency to avoid potential damage. Here are three popular methods:
1. Baking Soda Rinse
A baking soda rinse helps to swiftly cleanse hair without foam or lather.
• Mix 2 tablespoons of baking soda with about one cup of warm water.
• Apply to thoroughly wet hair, focusing on the scalp before working the solution through to the hair ends.
• Gently massage the scalp to loosen buildup and allow the solution to penetrate.
• Rinse thoroughly with clean water.
Tip: Avoid leaving the solution on for too long to prevent over-drying.
2. Baking Soda Paste
This method is ideal for spot treatment or moderate buildup.
• Combine 1 teaspoon of baking soda with a small amount of water to form a paste.
• Evenly distribute the paste on your damp hair, concentrating on the scalp and areas with noticeable buildup.
• Let it sit for 15–20 minutes for a mild exfoliating effect.
• Rinse completely with water.
3. Baking Soda and Apple Cider Vinegar Combo
For those seeking to rebalance pH after using baking soda, follow up with an apple cider vinegar (ACV) rinse.
• Prepare a baking soda solution as described above and apply it to your hair.
• After rinsing, mix 1 tablespoon of apple cider vinegar into one cup of water.
• Pour the ACV rinse over your hair to help restore a more natural pH level while adding shine.
• Rinse once more with cool water.
Incorporating a method like this one may also benefit those curious about the no poo approach to hair care. For detailed DIY tips and additional natural treatments, see our guidance on How to Apply Coconut Oil to Hair: Steps and Tips.
Frequency of Use and Best Practices
Experts generally recommend using baking soda treatments only 2–3 times per month. Using it too frequently can strip your hair of its natural moisture and protective oils, leading to long-term damage. Monitor how your hair responds and adjust the frequency as necessary. If you experience dryness or scalp irritation, it’s wise to reduce usage or discontinue the treatment altogether.
Baking Soda and Scalp Health: Balancing Benefits with Risks
It’s important to emphasize that while many find success with baking soda for hair, the lack of extensive clinical research means that results may vary. The high pH can potentially compromise the hair’s protective cuticle layer. If you have a sensitive scalp, color-treated hair, or already vulnerable hair due to environmental stress, consider less disruptive alternatives or test on a small section first.
For instance, people dealing with dandruff might find benefit in using baking soda as an occasional treatment, but if irritation occurs, switching to a milder alternative like a clarifying shampoo could be the solution. In such cases, you might explore options discussed in Shampoo for Dandruff and Hair Loss: Finding Relief.
Alternatives to Baking Soda
If you’re concerned about the potential drawbacks of baking soda use, several other natural and commercial treatments may be worth considering:
• Clarifying Shampoos: Designed specifically to remove product buildup without disturbing the scalp’s pH balance, these shampoos are an excellent alternative for regular hair cleansing. For instance, many beauty experts recommend trying a clarifying shampoo over DIY methods for long-term use.
• Apple Cider Vinegar Rinses: As noted earlier, ACV rinses can restore pH balance and remove residue while adding shine.
• Natural Hair Masks: Ingredients like clay, honey, and aloe vera offer gentle cleansing and conditioning. These substances not only cleanse but also nourish the scalp and hair.

Considerations for Different Hair Types
When deciding whether baking soda is right for you, consider your unique hair characteristics:
• Oily Hair: Occasional baking soda treatments may help manage oil and buildup, but moderation is key to avoid drying out the scalp.
• Dry or Damaged Hair: If your hair is already prone to dryness or breakage, the alkaline nature of baking soda could exacerbate these issues.
• Color-Treated Hair: Baking soda’s potential to strip natural oils means it might also fade hair dye. If maintaining color is a priority, seek gentler cleansing alternatives.
Listening to your hair’s response is essential. Conducting a patch test before applying baking soda to your entire head can help determine its suitability for your hair type and scalp sensitivity.
Frequently Asked Questions
How often can I use baking soda on my hair?
Limit use to 2–3 times per month. Overuse can lead to dryness, scalp irritation, and weakened hair structure.
Is baking soda safe for colored or chemically treated hair?
Baking soda may strip both natural oils and hair dye from color-treated hair. It’s advisable to avoid or minimize its use if you want to protect your hair color.
Can baking soda help with scalp conditions such as dandruff?
Some users report that baking soda’s exfoliating properties help reduce dandruff, yet its high pH may also irritate sensitive scalps. Consider alternative remedies like gentle clarifying shampoos if irritation occurs.
How do I rinse my hair properly after using baking soda?
Ensure you rinse thoroughly with warm water, and when using an ACV rinse, follow with a cool water splash to seal the cuticles and restore shine.
Does baking soda promote hair growth?
While it can clean your scalp effectively, there is no scientific evidence to suggest that baking soda directly stimulates hair growth. Its primary function is clarifying, not nourishing the hair follicles.
Final Insights
Baking soda can be a useful natural remedy for removing product buildup and revitalizing an oily scalp when used sparingly and correctly. However, its potential risks—especially regarding pH disruption and hair damage—underscore the importance of moderation and proper application. Individuals with sensitive, dry, or chemically treated hair should consider alternative cleansing methods or incorporate additional treatments, such as an apple cider vinegar rinse, to restore balance.
For those navigating hair health challenges and considering various treatment options, exploring diverse methods is essential.
