Apple cider vinegar for the scalp: benefits and uses
Apple cider vinegar for the scalp : applied as a diluted rinse, it rebalances the pH of the scalp, reduces dandruff and closes the hair cuticles for shinier, healthier hair.
A study published in the Journal of the American Academy of Dermatology () [1] confirms that theacetic acid present in apple cider vinegar has measurable antifungal properties, useful against Malassezia globosa, the fungus responsible for dandruff.
- Rebalances the scalp's natural acidic pH (ideally between 4.5 and 5.5)
- Reduces dandruff thanks to its antifungal properties
- It seals the hair fiber cuticles for added shine
- Regulates sebum production on oily scalps
- Soothes itching and skin irritation
Why is apple cider vinegar beneficial for the scalp?
Apple cider vinegar works primarily through its natural acidity. The pH of a healthy scalp is between 4.5 and 5.5. Most conventional shampoos have an alkaline pH (between 6 and 8), which disrupts this balance.
Apple cider vinegar, with a pH of approximately 2 to 3 before dilution, helps restore the scalp's natural acidity. This acidity creates an environment hostile to the bacteria and fungi responsible for dandruff and itching.
Many readers report that regular use of apple cider vinegar on the scalp has transformed their hair care routine in just a few weeks.
5 proven benefits of apple cider vinegar on the scalp
Apple cider vinegar for the scalp offers several benefits documented by scientific research.
1. Fighting dandruff
The acetic acid in apple cider vinegar inhibits the growth of Malassezia globosa [1], the fungus implicated in 80% of dandruff cases according to ANSES( 2022[2]. Bi-weekly application for 4 weeks shows a visible reduction in flakes.
2. Sebum regulation
Apple cider vinegar tightens scalp pores and regulates sebum production. Oily scalps particularly benefit from this natural astringent effect.
3. Itching relief
The anti-inflammatory properties of acetic acid reduce skin irritation. A study published in Skin Pharmacology and Physiology () [3] noted a significant decrease in pruritus within 3 weeks.
4. Shine and closure of the scales
Apple cider vinegar on the scalp closes the scales of the hair cuticle. Hair with closed scales reflects light better, appears smoother, and is easier to detangle.
5. Skin microbiome balance
The scalp has its own microbiome. Acetic acid promotes beneficial bacteria while inhibiting pathogens, according to a review published in Frontiers in Microbiology () [4].

Apple cider vinegar for the scalp: which product to choose?
Not all apple cider vinegars are created equal when it comes to hair care. The most effective apple cider vinegar for the scalp is the one that contains the "mother of vinegar".
- With the mother: unfiltered, unpasteurized, rich in enzymes and probiotics beneficial for the skin microbiome
- Organic is preferable: free from pesticide residues that could irritate the scalp
- Acetic acid titration: ideally between 4% and 6% for a balance of efficacy/tolerance
- Amber color: a sign of a minimally processed product
Apple cider vinegar and dandruff: what science says
Apple cider vinegar for the scalp is one of the best-documented natural remedies for dandruff. Its mechanism of action is based on three scientific pillars.
Antifungal action: Acetic acid disrupts the cell membrane of Malassezia. A concentration of 4% acetic acid is sufficient to inhibit their proliferation in vitro [1].
Keratolytic action: Apple cider vinegar on the scalp helps to loosen dead skin cells that accumulate on the scalp, thus reducing visible dandruff.
Acidifying action: By restoring an acidic pH, apple cider vinegar creates an environment unfavorable to microbial proliferation while strengthening the natural skin barrier.
The NCCIH () [5] recognizes the traditional use of apple cider vinegar in skin care, while stressing the need for further large-scale clinical studies.
Apple cider vinegar for the scalp: effects on hair growth
Apple cider vinegar on the scalp indirectly promotes hair growth by improving overall scalp health. A healthy scalp is the first prerequisite for optimal hair growth.
- Unclogs hair follicles blocked by sebum
- Improves microcirculation during application massage
- Reduces perifollicular inflammation that slows growth
- Removes styling product residue that suffocates the scalp
To date, there are no clinical studies demonstrating that apple cider vinegar directly stimulates hair growth on the scalp. However, improving the follicular environment is a well-established indirect factor.

Can apple cider vinegar be used on all hair types?
Apple cider vinegar for the scalp is suitable for most hair types, but some adjustments are necessary.
Curly and frizzy hair
Curly hair particularly benefits from apple cider vinegar on the scalp: it closes the cuticles, reduces frizz, and improves curl definition. Use a gentle dilution (1 part vinegar to 6 parts vinegar) to preserve natural moisture.
Colored hair
Apple cider vinegar on the scalp can help lock in color by sealing the hair cuticles after coloring. Use it highly diluted (1 part vinegar to 8 parts water) and avoid frequent applications, which could slightly alter the shade.
Dry and damaged hair
Opt for minimal dilution and combine apple cider vinegar with a nourishing vegetable oil. The goal is to benefit from its pH-balancing effect without further drying out the hair fiber.
Atopic or psoriatic scalp
Consult a dermatologist before using apple cider vinegar on your scalp if you have atopic dermatitis or scalp psoriasis. The acidity may worsen some open skin lesions.
