Why an Apple Cider Vinegar Rinse Can Give You the Hair of Your Dreams
The last time you cracked open a bottle of apple cider vinegar to assemble a salad dressing, you probably didn't have the impulse to slather some onto your scalp. (That stuff is pungent.) But a surface-level look into the DIY beauty corner of the internet reveals apple cider vinegar hair rinses are one of the most popular homemade beauty concoctions. What's more, you can find apple cider vinegar listed in the ingredients of numerous commercial haircare products. While it may not sound like the most enticing ingredient, ACV is an established haircare MVP. Find out why — and why you should totally try an apple cider vinegar hair rinse — below.
Are There Benefits to Doing an Apple Cider Vinegar Hair Rinse?
If you aren't familiar with the ingredient, apple cider vinegar results when apple juice is combined with yeast and undergoes fermentation. The vinegar is said to offer a range of health benefits when consumed, according to expert and board-certified anesthesiologist and physician Azza Halim, M.D. It's best known for potentially promoting fat burn (though most evidence stems from animal studies on rats and have limitations in regards to fat burn/weight loss in humans) and aiding in blood sugar control, but when applied topically, it also can play a part in helping your scalp and hair flourish, according to Dr. Halim.
Acetic acid, the acid in vinegar that results from the fermentation process, is mainly responsible for those hair benefits, including breaking down product buildup that may be clogging your hair follicles (which can hinder hair growth) in addition to acting as an antimicrobial, which can result in less dandruff and scalp pimples, she says.
An apple cider vinegar hair rinse is worth adding to your routine especially if you tend to struggle with product buildup, dandruff, and/or a dry and itchy scalp, says Dr. Halim. "ACV acts an antibacterial and antifungal, helping to diminish dry scalp and dandruff," she says. Dandruff may be caused by malassezia, a yeast that feeds on oils in the scalp, but can be combatted by the anti-fungal properties of apple cider vinegar. And even if you don't deal with dandruff, apple cider vinegar can help loosen dead skin cells and product build up on the scalp, providing gentle exfoliation.

What's more, an ACV scalp rinse can help restore balance to your scalp's pH level, according to Dr. Halim. (Refresher: pH is measured on a scale of 0 to 14, with numbers close to 0 being acidic, 7 being neutral, and 14 being alkaline.) Using alkaline hair products (most are) can result in an overly alkaline scalp (with a pH above the scalp's normal pH of around 5.5), which can contribute to a dry scalp. (Apple cider vinegar has a pH of 2-3 which helps counteract the pH of alkaline products, bringing your scalp closer to that 5.5 pH target. That may also lead to shinier hair, since lowering strands' pH can help seal up the cuticle (your hair's outermost, protective layer), locking in moisture. If you have color-treated hair, apple cider vinegar may actually help extend the life of your dye job due to those cuticle-sealing properties, says Dr. Halim. (When your hair's cuticle is more raised, pigment particles can more easily escape just as moisture can.)
Long story short, there are more than enough reasons why you might want to consider adding an apple cider hair rinse to your routine.
How to Incorporate an ACV Hair Rinse Into Your Routine
Incorporating apple cider vinegar into your hair care routine is pretty simple. If you make your own apple cider vinegar hair rinse at home, you always want to dilute the vinegar to avoid burning your skin. For convenience, you also have the option to buy a hair product that already has ACV in it. (Oftentimes, this is the better route if you're turned off by the smell of vinegar.) Dr. Halim prefers to dilute apple cider vinegar and make her own rinse. To follow suit, try her method below one to two times per week on wash days.
- Dilute one part apple cider vinegar with 4-5 parts cool or lukewarm water (e.g. two ounces ACV with 8 ounces water) in a spray bottle.
- After shampooing your hair, spray the diluted apple cider vinegar directly onto your hair and scalp. Gently massage your hair and scalp until both are completely saturated and coated evenly in the diluted ACV.
- Let the apple cider vinegar rinse sit for about 5 minutes, then rinse your hair with cool water to remove the ACV.
- Apply a conditioner and finish styling your hair as normal. This will ensure your hair remains moisturized and does not feel dry or brittle.
