Apple Cider Vinegar for Hair: Your Complete Guide to Healthier, Shinier Strands
Apple cider vinegar (ACV) has rapidly become one of the most discussed natural remedies in the world of hair care. Touted for its potential to improve scalp health, boost shine, fight dandruff, and restore softness, this humble kitchen staple has made its way from salad dressings into bathroom cabinets everywhere. But does ACV really deliver on all these promises—and are there risks to be aware of? This comprehensive guide explores everything you need to know about apple cider vinegar for hair, backed by dermatologists and real-world results.
What Is Apple Cider Vinegar and Why Is It Used for Hair?
Apple cider vinegar is a type of vinegar made from fermented apple juice. It’s widely known for its natural antibacterial and antifungal properties, primarily due to its high acetic acid content. In hair care, ACV is used to help cleanse, balance, and clarify both the scalp and the hair itself.
While it has a long-standing reputation as a home remedy for everything from sore throats to sunburns, its application for hair health is receiving scientific attention for several reasons:
- Restores pH balance: ACV is acidic, and many hair and scalp issues stem from a disrupted pH level, often caused by frequent shampooing and product build-up.
- Combats microbes: Its ability to combat bacteria and yeast helps prevent dandruff and scalp irritation.
- Natural exfoliation: ACV contains alpha hydroxy acids, especially malic acid, which gently remove dead skin cells and product residue.
Is Apple Cider Vinegar Good for Hair?
The short answer is: yes, for many people, apple cider vinegar offers a range of potential hair benefits. Dr. Mona Gohara, a board-certified dermatologist, explains that ACV’s antimicrobial properties make it effective in reducing dandruff and soothing irritated scalps. “Apple cider vinegar has natural antibacterial and antifungal properties, which makes it pretty effective in killing and preventing dandruff-causing yeast on the scalp.”
These benefits are especially significant for those struggling with flaky or itchy scalps, irritation, or tedious product build-up that leaves hair looking dull and lifeless.
- Reduces dandruff: Fights yeast overgrowth linked to dandruff and flaky scalp concerns.
- Calms irritation: Its anti-inflammatory properties can reduce itchiness and redness on contact.
- Clarifies the scalp and strands: Natural malic acid clarifies without stripping essential oils, removing residue from styling products.
- Boosts shine and smoothness: By sealing the cuticle and balancing pH, ACV leaves hair looking sleeker and feeling softer.
Important: Never apply undiluted apple cider vinegar directly to the scalp or hair—it’s too acidic and may cause irritation or damage. Always dilute before use, typically mixing one part ACV with four or five parts water.
How Does Apple Cider Vinegar Work in Hair Care?
To understand ACV’s effectiveness, it helps to know a little about the science of hair and scalp pH. The ideal pH for both the scalp and hair is around 5.5, which supports the acid mantle—a protective layer that wards off harmful microbes and environmental stress. Most shampoos and water have a higher, more alkaline pH. When we wash our hair, these products raise the pH, potentially leaving hair feeling rough, weak, or frizzy.
What others are reading
ACV’s pH ranges from 2 to 3, which helps bring hair and scalp back to their optimal acidity after shampooing. Here’s how ACV works in hair care:
- Balances scalp and hair pH: Restores acidity, closing the hair cuticle and making hair smoother and less prone to tangling or breakage.
- Seals the cuticle: Lowering the cuticle’s pH makes it lay flat, boosting shine and reducing frizz.
- Improves manageability: Smoother cuticles mean hair is easier to detangle and style.
- Clarifies: Removes excess oil, sweat, and product build-up without stripping natural oils.
Key Benefits of Apple Cider Vinegar for Hair and Scalp
- Combats Dandruff: ACV’s acidity creates an environment less favorable to the yeast that causes dandruff, reducing flakiness and irritation.
- Soothes Irritated Scalps: Natural anti-inflammatory properties calm itchiness and redness.
- Exfoliates Gently: Alpha hydroxy acids help slough off dead skin and unclog follicles, promoting a healthier scalp.
- Clarifies Hair: Breaks down product residue and excess oils, leaving hair fresher and cleaner.
- Boosts Shine: Seals the cuticle for sleeker, shinier, and less frizzy hair.
- Improves Manageability: Smoother hair is easier to brush, detangle, and style.
- May Prolong Color: By reducing the need for frequent washing and sealing the cuticle, ACV can help dyed hair keep its vibrancy.
- Provides Nutrient Support: While it doesn’t provide significant vitamins, ACV does contain trace minerals like potassium and calcium, which support hair health.

Who Should Use Apple Cider Vinegar for Hair?
Most hair types can benefit from the occasional ACV rinse or treatment, especially those with:
- Dandruff or flaky scalps
- Flat, dull, or greasy hair prone to product build-up
- Frizzy strands or tangles
- Scalp irritation, itchiness, or redness
- Color-treated hair seeking longer-lasting vibrancy
However, individuals with very dry or brittle hair, or highly sensitive skin, should use ACV sparingly and patch-test before full application.
How to Safely Use Apple Cider Vinegar on Hair
Never pour ACV directly onto your head. Due to its high acidity, undiluted ACV can cause stinging, irritation, or hair shaft damage. Here’s how to apply it safely and effectively:
- Prepare the Rinse: Mix 1 part apple cider vinegar with 4 or 5 parts water. Use filtered or distilled water for best results.
- Apply to Scalp and Hair: After shampooing, slowly pour the ACV solution over hair, focusing on the scalp. Massage gently for 1–2 minutes.
- Let Sit: Allow it to sit for a few minutes (2–5 minutes is typical), then rinse thoroughly with cool water.
- Condition, If Desired: Apply your regular conditioner to the ends or skip if your hair already feels conditioned.
- Frequency: Most people benefit from using an ACV rinse once a week or once every other week. Overuse can lead to dryness, especially for fine or dry hair types.
ACV-Infused Shampoos and Conditioners
For those seeking the benefits of apple cider vinegar without the mixing or strong scent, look for shampoos and conditioners formulated with ACV. These products balance the acidic effects with other nourishing ingredients, making them particularly suitable for sensitive scalps or those new to ACV hair care.
- Convenience: No mixing or risk of improper dilution; easy to use like any regular shampoo.
- Balanced formulas: Typically include hydrating agents to counteract potential dryness.
- Scent-masking: Many mask the natural vinegar scent with essential oils or fragrances.

Are There Any Risks or Side Effects?
- Scalp Irritation: If used undiluted or too frequently, ACV may cause burning, stinging, or redness.
- Dryness or Brittleness: Overuse may leave hair parched, particularly for those with already dry or textured hair.
- Color Fading: Though ACV can help some with color retention, excessive use—especially if undiluted—may strip hair dye faster in some cases.
- Allergic Reactions: Rare, but always patch-test before full use if you’re new to ACV treatments.
If you develop significant irritation or discomfort, discontinue use and consult a dermatologist.
Expert Tips for Getting the Most From Apple Cider Vinegar Hair Care
- Always dilute apple cider vinegar—the classic starting ratio is 1 part ACV to 4 or 5 parts water.
- Apply the rinse after shampooing, not before, for optimal clarifying and pH-balancing results.
- Use cooler water for the final rinse to further help close the cuticle and add shine.
- If the vinegar scent lingers, rinse again or follow with a leave-in conditioner.
- For an added boost, combine your ACV rinse with a few drops of nourishing oils like argan or jojoba for dry ends.
- Monitor your scalp and strands; increase or decrease frequency as needed based on hair response.
Frequently Asked Questions (FAQs)
Is apple cider vinegar safe for color-treated hair?
Apple cider vinegar can help seal the hair cuticle, which may extend the life of hair dye for some people. However, if used too frequently or in high concentrations, it can potentially strip color faster. Always use a diluted rinse and limit use to once a week or less on colored hair.
Will apple cider vinegar make my hair smell?
The vinegar scent usually fades as hair dries. Rinsing thoroughly and optionally following with a scented conditioner or leave-in treatment will mask most of the odor.
Can ACV help with scalp psoriasis or eczema?
While ACV’s anti-inflammatory and antimicrobial properties may soothe mild irritation, it is not a substitute for medicated treatments. If you have chronic scalp conditions, consult your dermatologist before use.
How long should I leave an ACV rinse on my hair?
Generally, 2–5 minutes is sufficient to allow ACV to clarify and balance pH before rinsing out thoroughly with cool water.
What type of ACV is best for hair?
Choose raw, unfiltered apple cider vinegar, ideally “with the mother,” as it retains more of the beneficial bacteria and nutrients. Filtered versions are less potent but may have a milder scent.
The Bottom Line: Should You Try Apple Cider Vinegar for Your Hair?
For those seeking natural, affordable, and effective additions to their hair care routine, apple cider vinegar stands out as a versatile solution. Its ability to balance pH, clarify, fight dandruff, and enhance shine is supported by both anecdotal experience and modern dermatological research. Used correctly—with proper dilution and frequency—it’s a safe and effective option for most hair types.
However, individual results vary, and those with sensitive skin or severe scalp conditions should consult a skincare professional before adding anything new to their regimen. As with any beauty treatment, moderation and consistency are key.
