So, how do you actually use it at home? We investigated. What does this have to do with ACV rinses? Well, it can explain the mechanisms behind the benefits. Since ACV is more acidic (around 2-3 on the pH scale), it can help lower the hair fiber’s pH back to normal levels after rinsing. So the idea is that when you rinse it with something acidic—hello, apple cider vinegar!—it brings the pH back down and seals the cuticle shut, leading to shiny, soft strands. Additionally, because the ACV is sealing the cuticle, it can help the fiber hold onto the pigment longer. Lactic acid, in particular, is a very beneficial acid for skin health as it can act as humectant as well. This means it can pull in water and hydration while it’s exfoliating the epidermis. You can also find premixed ones that work very well—and usually have added ingredients to amplify the apple cider vinegar properties. You know, in case DIY isn’t your thing. Here’s our favorite hair care products with ACV. With your apple cider vinegar of choice, mix in ½ tablespoon of ACV for every 1 cup of cold water to dilute the vinegar. Sure, you could try mixing it in a jar or glass, but you will have less control as you apply it throughout the scalp (plus, they tend to be heavier and easier to drop; you don’t want broken glass in your shower.) Another easy option is a clean condiment bottle with a pointed nozzle to better get under the hair and directly on the scalp. As a final packaging trick: Try an old spray bottle, like a non-aerosol hair-spray tube, so you can spray it on the scalp and hair in the shower. But don’t overthink it: Whatever you have around the house will likely suffice. Here’s a good place to start, and from here you can adjust based on your personal experience. No matter the way you use it, be sure to let it sit on the hair for upwards of a few minutes before you rinse it out. So it makes sense that a cuticle-sealing rinse would be the right move—however, DIY recipes might be too clarifying for some color-treated hair. Since chemical processing makes hair more susceptible to breakage, you need to be extra careful with all that you’re using. Many professional rinses also include added ingredients to make them extra gentle and color-safe. Clean and natural-leaning dpHue’s Apple Cider Vinegar Hair Rinse has argan oil, aloe vera, and a proprietary color-locking blend to help keep your color sharp and make it last longer. Hairstory’s New Wash (Deep) has keratin, oils, and apple cider vinegar, too. As always, if you have concerns about using ACV in your routine, consult with your hair colorist or stylist.
