Is It Safe To Use Apple Cider Vinegar For Hair?
Summary
Apple cider vinegar (ACV) can be safely used on hair and scalp when properly diluted, offering benefits such as improved shine, pH restoration, and residue removal. Applying it undiluted or too frequently can cause damage, so a specific protocol is recommended. Water quality is also highlighted as an important factor in scalp and hair health.
Key Takeaways
- Dilution is essential — never apply apple cider vinegar directly at full concentration, as it can damage hair
- The correct dilution is 1 tablespoon of ACV per 16 ounces of water
- Use ACV as a post-shampoo rinse, not a leave-in treatment
- Limit use to once or twice a week rather than daily application
- ACV can help restore scalp pH, which is naturally slightly acidic
- ACV rinses can remove product residue left behind by shampoos and conditioners
- Chlorine and fluoride in tap water are halogens that can damage hair and cause scalp issues — a shower filter is recommended

Benefits of Apple Cider Vinegar on Hair and Scalp
Apple cider vinegar is widely known for its internal benefits, including supporting digestion and blood sugar regulation. Applied topically, it can also benefit the scalp and hair due to the skin’s naturally slightly acidic nature. Specific benefits mentioned include:
- pH restoration of the scalp, which is naturally acidic
- Improved hair shine
- Removal of product buildup from shampoos and conditioners
How to Use ACV on Hair (Correct Protocol)
- Dilution ratio: 1 tablespoon of apple cider vinegar to 16 ounces of water
- Application method: Use as a rinse after shampooing and conditioning — do not apply undiluted
- Contact time: Do not leave it sitting in the hair for extended periods; treat it as a rinse
- Frequency: Once or twice per week is sufficient — daily use is not recommended
What to Avoid
- Applying ACV at full, undiluted concentration — this can damage the hair shaft
- Daily use, which may be excessive for most people
- Leaving ACV on the hair for a prolonged period
Water Quality and Hair Health
Dr. Berg emphasizes that tap water quality plays a role in scalp and hair health. Chlorine and fluoride are identified as halogens — highly reactive chemicals that can:
- Irritate the skin and scalp
- Contribute to acne-like issues
- Damage hair over time
Installing a shower or tap filter capable of removing chlorine and fluoride is recommended as a complementary step to improving hair and scalp health.
