What you should know about Baking Soda on hair
Baking soda, known chemically as sodium bicarbonate, is a common household item with various uses in beauty and hair care. It is an alkaline substance that can effectively cleanse by breaking down dirt and oil.
In hair care, baking soda is often used for its ability to remove product buildup and clarify the scalp. But, its high pH can disrupt the natural balance of the scalp and hair, potentially leading to dryness and damage.

The Common Side Effects of applying baking soda on hair
Dryness
Baking soda’s high alkalinity strips the natural oils from the hair and scalp, which are essential for keeping hair moisturized. Without these oils, hair can become excessively dry and lose its natural shine and softness.
Brittleness
Along with dryness, the lack of natural oils makes the hair more prone to brittleness. Brittle hair is more rigid and less flexible, making it more susceptible to breakage under stress.
Increased hair breakage
The weakening of the hair shaft due to baking soda’s harshness can lead to increased hair breakage. As the hair becomes more fragile, it breaks more easily, especially during brushing or styling.
Split ends
Baking soda can cause the ends of the hair to split because it depletes the hair of moisture and weakens its structure. Split ends can make hair look frizzy and damaged, requiring frequent trims to manage.
Scalp irritation
The high pH level of baking soda can disrupt the natural acidity of the scalp, leading to irritation. This can manifest as a burning or tingling sensation, which is uncomfortable and can worsen with continued use.
Redness
Irritation from baking soda can cause the scalp to become red and inflamed. This redness is a sign of the scalp’s distress and its reaction to the alkaline nature of baking soda.
Itching
As the scalp becomes dry and irritated, itching is a common side effect. Persistent itching can lead to scratching, which may further damage the scalp and hair follicles.
Flakiness
The disruption of the scalp’s natural balance can cause flakiness or dandruff. Baking soda can lead to dry, flaky patches on the scalp, which can be unsightly and uncomfortable.
Fading of hair color
For those with dyed hair, baking soda can strip away the color more quickly. Its abrasive properties can cause the dye to wash out faster, leading to a duller appearance.
Damage to chemically treated hair
Chemically treated hair, such as permed or relaxed hair, is already weakened by the treatments. Baking soda can exacerbate this damage, leading to increased breakage and loss of the desired effect of the treatments.
Weakened hair shaft
Regular use of baking soda can weaken the hair shaft, making it more prone to damage from environmental factors and styling. This weakening can result in hair that looks and feels less healthy.
Altered hair texture
Baking soda can change the natural texture of the hair, making it feel rough and coarse. This alteration can make hair harder to manage and style, often requiring additional products to restore its smoothness.
Factors Influencing Side Effects of applying baking soda on hair
1. Hair Type
The natural texture and thickness of your hair play a significant role in how it reacts to baking soda. Fine or thin hair is more likely to experience severe dryness and breakage, while coarser hair may be more resilient but still suffer damage over time.
2. Duration of Application
Leaving baking soda on your hair for extended periods can increase the likelihood of adverse reactions. Shorter application times may reduce the risk of severe dryness and irritation.
3. Hair Treatments
Hair that has been chemically treated, such as colored, permed, or relaxed, is more vulnerable to the damaging effects of baking soda. These treatments already weaken the hair, and baking soda can intensify the damage.
4. Environmental Factors
Exposure to environmental stressors like sun, wind, and pollution can compound the damaging effects of baking soda. Hair that is already stressed by these factors may react more negatively to baking soda treatments.
5. Follow-Up Care
The way you care for your hair after using baking soda can influence the severity of side effects. Using moisturizing conditioners and avoiding heat styling can mitigate some of the damage caused by baking soda.

Natural Ingredients with Similar Benefits but Fewer Risks
Instead of using baking soda, there are several natural ingredients that offer similar benefits without the potential risks:
- Honey: Honey is a natural humectant, meaning it helps to attract and retain moisture in the hair. It also has antibacterial properties that can help to cleanse the scalp without disrupting its natural pH balance.
- Aloe Vera: Aloe vera is known for its soothing and hydrating properties. It can help to moisturize the hair and scalp, reduce inflammation, and promote healthy hair growth.
- Coconut Oil: Coconut oil is rich in fatty acids that can penetrate the hair shaft to moisturize and strengthen the hair. It helps to prevent protein loss from the hair, making it less prone to damage and breakage.
Proper Hair Care Routines and Gentle Products
In addition to using natural ingredients, adopting a proper hair care routine and using gentle products can help to maintain hair health:
- Use a Mild Shampoo: Opt for sulfate-free and pH-balanced shampoos that are gentle on the hair and scalp. Look for products that are specifically formulated for your hair type and concerns.
- Condition Regularly: Use a conditioner after every wash to replenish moisture and improve manageability. Choose a conditioner that matches your hair type and addresses specific needs, such as hydration, repair, or volume.
- Limit Heat Styling: Reduce the use of heat styling tools such as blow dryers, straighteners, and curling irons, as excessive heat can damage the hair and cause breakage. When using heat styling tools, always use a heat protectant spray to minimize damage.
- Protect Your Hair from the Sun: UV rays can damage the hair cuticle and cause dryness and color fading. Wear a hat or use hair products with UV protection when spending time outdoors.
- Avoid Overwashing: Washing your hair too frequently can strip away its natural oils and lead to dryness and irritation. Aim to wash your hair no more than two to three times a week, or as needed based on your hair type and lifestyle.
Personal Testimonies and Case Studies
- Alyssa’s Color Fading Nightmare “As someone who loves coloring my hair vibrant shades, I tried baking soda to help remove some product buildup. Unfortunately, it stripped my hair color far more than I anticipated. My bright red hair turned into a washed-out pink after just one application. I was devastated. I stopped using baking soda and began using color-safe products to preserve my hair color. It was an expensive lesson to learn.” – Alyssa, 25
- Mark’s Experience with Weakened Hair Shaft “I used baking soda as a shampoo alternative for about a month. Initially, it felt like my hair was cleaner, but then it started feeling weak and straw-like. It lost its natural shine and became really rough to touch. I stopped using baking soda and started using a protein treatment once a week to help strengthen my hair again. It took a while, but my hair eventually regained its strength and softness.” – Mark, 27
Dermatological Insights
- Dr. Alan Bauman, Hair Restoration Physician “While baking soda has its uses in other areas, it’s not suitable for hair care. Its high pH level can cause significant damage to the hair’s structure and the scalp’s health. Modern hair care products are formulated to balance cleansing with maintaining hair health, something baking soda simply cannot achieve. For anyone looking to improve their hair care routine, I’d advise sticking to products that are specifically designed for that purpose.”
- Dr. Jennifer Trent, Dermatologist “Baking soda can act as an abrasive, which is why it might seem effective for cleansing at first. However, this abrasiveness can damage the cuticle, the outer protective layer of the hair. Over time, this can lead to increased hair breakage, split ends, and a general weakening of the hair shaft. It’s important to use products that maintain the integrity of the hair cuticle rather than compromise it.”
In conclusion,
Using baking soda on hair can have harmful effects. It can make the hair dry, brittle, and more likely to break. Baking soda may also irritate the scalp, leading to redness, itching, and flakiness. For those with colored or chemically treated hair, baking soda can cause the color to fade faster. To keep hair healthy, it’s best to avoid using baking soda and instead opt for gentler hair care products.
