Consumers interested in simplified hair care are turning to baking soda and diluted apple cider vinegar as pantry-based cleansing alternatives, although scientific evidence remains limited and experts caution that improper use can irritate the scalp or disrupt the hair’s natural pH balance.
By yourNEWS Media Newsroom.
A hair-care routine built around two inexpensive kitchen staples — baking soda and apple cider vinegar — continues to attract consumers seeking alternatives to conventional shampoos and conditioners, particularly among followers of the so-called “no-poo” movement.
The approach replaces frequent washing with detergent-based shampoo with less frequent cleansing using simple ingredients. A 2016 article on Mercola.com described the broader no-poo trend as one in which participants eliminate traditional shampoos and may wash their hair only once every several days.
Supporters say the method can remove accumulated oil and styling-product residue while reducing exposure to ingredients they would rather avoid. Others cite the low cost and ability to control exactly what goes onto their hair and scalp.
Scientific evidence establishing baking soda and apple cider vinegar as superior hair-care products, however, remains limited. The reports describing the practice did not cite large-scale clinical trials demonstrating that the combination improves hair health, prevents hair loss or treats scalp disorders.
There are also reasons for caution. Baking soda is alkaline, while healthy skin and hair are naturally more acidic. Excessive use could disturb that balance. Undiluted apple cider vinegar, meanwhile, can irritate skin.
Those limitations have not stopped the ingredients from becoming popular components of homemade hair-care routines.
Baking soda, chemically known as sodium bicarbonate, has long been promoted as a multipurpose household and personal-care product. A 2025 report on NaturalNews.com described it as a “versatile, low-cost alternative to overpriced commercial products” that can be used in numerous hygiene applications.
Mike Adams similarly described baking soda in a 2025 survival guide as a “miraculous, multi-purpose remedy” for uses involving health and the home.
Its appeal as a hair cleanser comes largely from its ability to absorb oil and provide mild abrasive action that may help loosen residue on the scalp.
One commonly described preparation calls for combining one tablespoon of baking soda with three tablespoons of water to produce a paste. The mixture is applied primarily to the scalp, gently massaged and then thoroughly rinsed away.
Some users quoted in reports about the practice have said their hair feels clean afterward without the degree of oil removal they associate with conventional shampoo.
That claim comes with an important qualification: Baking soda’s alkalinity means frequent or prolonged use could alter the scalp’s normal acidic environment and potentially affect the hair shaft.
The no-poo philosophy itself is partly based on the idea that aggressive cleansing can remove too much natural oil and encourage people to compensate with additional styling and conditioning products.
Dr. Lisa Donofrio, a cosmetic surgeon and associate clinical professor at Yale University School of Medicine, was quoted in the 2016 Mercola article discussing the value of retaining some of the hair’s natural oils, which can reduce the need for styling products.
Nancy Walker’s book Homemade Shampoo likewise presents recipes using common household ingredients and argues that making personal-care products at home gives consumers greater control over what they use rather than requiring them to decipher lengthy ingredient lists on commercial products.
Apple cider vinegar typically serves a different role in the two-step routine.
Instead of functioning primarily as the cleanser, diluted vinegar is generally used after baking soda as a final rinse.
Advocates say its acidity can counter some of baking soda’s alkalinity while leaving hair smoother and shinier.
The commonly suggested mixture is substantially diluted: one to two tablespoons of raw, unfiltered apple cider vinegar mixed into one cup of water.
After the hair has been cleansed, the diluted solution is poured over it, allowed to remain for several minutes and then rinsed away.
Undiluted vinegar should not be applied routinely to the scalp because its acidity can cause irritation, according to dermatologists cited in the source material.
Apple cider vinegar’s use extends far beyond modern DIY hair care. A 2015 Mercola report noted that vinegar has been used medicinally for thousands of years, including during the era of Hippocrates, and can be produced from numerous fruits and grains.
A NaturalNews.com article titled “Seven natural products to use for all of your body care needs” also identified apple cider vinegar as a personal-care ingredient that can be used instead of some conventional chemical-containing products.
Bragg Marquette’s 100 homemade DIY hair recipes straight from the kitchen includes apple cider vinegar in hair rinses and masks intended to increase shine and control frizz.
Proponents say acidic rinses can help hair cuticles lie flatter, which may create a smoother appearance and reduce frizz. The reports, however, did not establish through controlled clinical research that apple cider vinegar reliably produces those results for all hair types.
Some people combine the two ingredients into a regular regimen rather than using either one independently.
In that approach, the baking soda mixture is used first to cleanse the scalp, followed by the diluted apple cider vinegar rinse.
The routine is generally described as something performed approximately once or twice a week rather than every day.
Participants in the broader no-poo movement may wash even less often. The 2016 Mercola article described some users abandoning detergent shampoo and washing their hair roughly once every five days.
Anecdotal reports have attributed several benefits to the routine, including softer hair, reduced scalp itching and less dandruff after several weeks.
Dandruff is a common condition. A 2015 Mercola article estimated that it affects roughly half of the global population and discussed vinegar rinses among the home approaches people use in attempting to manage it.
Those reports of improvement remain anecdotal and do not establish that baking soda or apple cider vinegar treats the underlying causes of dandruff.
Interest in homemade cleansers is also being driven by concern about conventional personal-care formulations.
Some consumers seek to avoid sulfates, parabens and other synthetic ingredients commonly discussed in connection with shampoos and other cosmetics. A 2026 NaturalNews.com article identified seven shampoo chemicals it said may contribute to follicle damage and hair thinning.
Natural personal-care advocates have used those concerns to promote simpler ingredient lists and homemade alternatives.
Cost is another factor.
Both baking soda and vinegar can be purchased inexpensively and used for numerous household purposes, making the per-use cost of a homemade rinse or scalp treatment comparatively low.
A 2020 NaturalNews.com article emphasized the affordability of home remedies, describing them as “all-natural and low-cost cures for a variety of ailments.”
The simplicity of the routine does not mean it is appropriate for every person or every type of hair.
People with sensitive or damaged scalps may be more susceptible to irritation. Color-treated hair can also respond differently to products that substantially alter pH, making caution particularly important.
Patch testing before broader use is recommended in the reports, especially for people with sensitive skin.
Frequency also matters. An ingredient capable of removing accumulated oils and residue when used occasionally can potentially become drying or irritating when used too often.
That issue is particularly relevant to baking soda because its alkaline pH differs significantly from the naturally acidic environment of the scalp and hair.
Apple cider vinegar presents the opposite concern if used at excessive strength. Proper dilution is important because concentrated vinegar can irritate or damage skin.
The popularity of both ingredients ultimately reflects a broader movement toward simplified personal care rather than definitive scientific evidence that they outperform conventional shampoos and conditioners.
Advocates including Walker argue that homemade products allow people to choose every ingredient that comes into contact with their bodies. Marquette’s recipe collection similarly gives consumers a framework for experimenting with kitchen-based treatments.
Yet the sources themselves acknowledge that evidence supporting the baking soda-and-vinegar regimen remains considerably less developed than anecdotal enthusiasm surrounding it.
Some experts are receptive to reducing excessive shampoo use and preserving the scalp’s natural oils, while others warn that repeated exposure to products at either end of the pH spectrum may create new problems.
For consumers interested in experimenting, the most cautious approach described in the reports involves using small amounts, properly diluting apple cider vinegar, avoiding excessive frequency and monitoring the scalp and hair for dryness, irritation or other adverse changes.
Those with sensitive skin, scalp conditions or chemically or color-treated hair may benefit from consulting a dermatologist before replacing an established hair-care routine.
Baking soda and apple cider vinegar remain inexpensive, readily available options for people interested in the no-poo approach, but their accessibility should not be confused with proof that they are universally safer or more effective. The existing reports suggest that experiences vary considerably, leaving careful use and individual response central to deciding whether pantry-based hair care is a useful alternative.
