As someone in pursuit of longer, stronger locks, I’m willing to try nearly anything. Scalp care has become a top priority for me in my hair growth journey—after all, healthy hair starts at the root. That’s why a recent trend caught my attention: kombucha for hair.
But can fermented formulas—such as scalp treatments containing kombucha and other probiotic-rich ingredients—really transform hair health, or is this just another fleeting beauty fad? I delved into the science, checked out what experts have to say about it and even tried it myself to find out.
WHAT IS KOMBUCHA?
Kombucha is a fermented tea made from green or black tea, sugar, yeast, and bacteria. Originating in China around 2,000 years ago, it is created by fermenting sweetened tea with a SCOBY (symbiotic colony of bacteria and yeast) for one to two weeks. The result is a lightly sparkling, tangy drink with minimal alcohol, rich in probiotics, amino acids, polyphenols, and essential vitamins like B1, B3, B12, C, and magnesium.
Known for its gut-health benefits, kombucha promotes digestion and immune function by supporting beneficial bacteria. Recently, kombucha has also gained attention in the beauty industry for its potential benefits in nourishing the scalp and hair.
the kombucha trend
Many enthusiasts have started incorporating kombucha into their daily routines, not only for its internal health benefits but also for its external applications. In the realm of beauty, kombucha is praised for its ability to help balance the skin’s pH levels, potentially leading to a clearer, more radiant complexion. Its antioxidant properties may also protect the skin from environmental stressors, contributing to a youthful appearance. Additionally, the versatility of kombucha has inspired a plethora of flavours and variations, from classic options like ginger and lemon to more exotic blends featuring hibiscus or elderflower. Home brewers enjoy experimenting with their own unique combinations, creating a personalized experience that extends beyond taste to a holistic lifestyle choice.
As the kombucha trend continues to grow, so does the research into its myriad of benefits. Whether sipped as a refreshing beverage, used as a skincare ingredient, or explored as a culinary ingredient, kombucha proves to be a fascinating and multifaceted addition to modern wellness practices. And now, even hair.
HOW DOES KOMBUCHA BENEFIT HAIR?
Just as gut health impacts skin health, experts now acknowledge the importance of a balanced scalp microbiome for optimal hair growth. Here’s how kombucha can benefit scalp and hair health:
Balancing the Scalp Microbiome
The scalp is home to a varied ecosystem of microorganisms, and maintaining this balance is crucial for preventing dandruff, itchiness, and inflammation. Kombucha, which is rich in probiotics, may help regulate the scalp microbiome by reducing harmful bacteria and creating a nurturing environment for hair follicles to flourish.
Exfoliation and Detoxification
Kombucha contains organic acids like acetic acid and gluconic acid, known for their mild exfoliating properties. These acids can effectively dissolve excess oil, product buildup, and dead skin cells, resulting in a refreshed and balanced scalp.
Strengthening Hair and Minimising Breakage
Packed with antioxidants and amino acids, kombucha may protect hair from oxidative stress and reinforce the strands. The polyphenols and B vitamins present in kombucha aid in keratin production, which can help reduce breakage and promote overall hair health.
Stimulating Hair Growth
Recent studies indicate that fermented ingredients like those in kombucha might encourage the anagen (active growth) phase of the hair cycle. Kombucha’s active compounds could enhance blood circulation to hair follicles, potentially leading to healthier, faster hair growth.
Regulating pH for a Healthier Scalp
Maintaining a balanced scalp pH is essential for preventing dryness, irritation, and excessive oiliness. The slightly acidic nature of kombucha (usually around pH 3-3.5) can help regulate the scalp’s pH, making it less conducive to fungi and bacteria that cause dandruff and other scalp issues.
The Rise of Fermented Ingredients in Haircare
Fermentation has become a popular concept in skincare and haircare, extending beyond just kombucha. This process enhances the bioavailability of natural ingredients, making nutrients and active compounds smaller and easier for the skin and hair to absorb.
In haircare, fermented ingredients can break down proteins into amino acids, strengthening the hair structure. They also increase antioxidant potency to protect against environmental damage and improve scalp hydration and barrier function. As a result, many brands are incorporating kombucha and other fermented botanicals into their products, claiming to provide deeper nourishment compared to traditional ingredients alone.
WHAT ARE THE POSSIBLE RISKS?
While kombucha seems to offer several benefits for scalp and hair health, there are important factors to keep in mind.
Acidic Nature
Kombucha is naturally acidic, and excessive use might interfere with the scalp’s natural protective barrier. To prevent this, it is advisable to dilute kombucha or opt for specially formulated haircare products that incorporate kombucha safely.
Possible Sensitivities
Some individuals may have sensitivities to fermented ingredients, which can lead to mild irritation or discomfort. To avoid adverse reactions, conducting a patch test before using kombucha-infused products is recommended.
Limited Research
Although preliminary studies show potential, the body of research on kombucha’s effectiveness in haircare is still growing. More comprehensive clinical trials are necessary to confirm its benefits and ensure safe usage.
When incorporating kombucha into your haircare routine, it’s essential you proceed cautiously and stay informed about the latest research findings. Although this is a natural product, it might still have some negative effects on you. My go-to way to trial products? Patch testing.
HOW TO IMPLEMENT KOMBUCHA INTO YOUR HAIR ROUTINE
If you’re curious about incorporating kombucha into your hair care routine, like me, you can either do a DIY Kombucha Rinse by combining equal parts kombucha and water, then pouring it over your scalp after shampooing. Allow it to sit for 5-10 minutes before rinsing with cool water. This technique helps clarify the scalp and restore pH balance. Alternatively, many hair care brands are now offering shampoos, conditioners, and scalp treatments enriched with kombucha. These products are designed for safe and effective use, often featuring additional ingredients like botanical extracts and probiotics.
BRand recommendations
As usual, I’ve put together a list of what I think are the best kombucha based products out there (quality to price).

As well as Kombucha, fermented rice water is another beneficial ingredient that has been used for centuries in Asian beauty rituals, prized for its ability to strengthen hair, promote growth, and enhance shine. Rich in amino acids, vitamins, and antioxidants, the fermentation process boosts its potency—making nutrients more bioavailable and easier for the hair and scalp to absorb.
Today, this ancient remedy is being reimagined in modern formulations, offering a natural, science-backed solution for healthier hair.
