I love doing this whenever I feel like my hair needs a reset. When I haven't shampooed my hair in a week...this tonic balances the scalp biome, oil production, and breaks down the “gunk” that builds up. ACV is one of one of my most favorite affordable and safe remedies for all things skin, scalp, and gut related. 
  • Mix 1 to 4 tablespoons of apple cider vinegar (ACV) with 8 ounces of water in a Mason jar, plastic squeeze bottle, spray bottle, or other container. Experiment to find a dilution that works best for your hair type. As a rule of thumb, dry hair likes less ACV and oily hair likes more.

To Use

After shampooing apply the vinegar rinse. Pour the rinse onto wet hair. Massage into hair and scalp and pay special attention to the ends. Be sure to avoid your eyes and allow it to sit on the hair for a few minutes.

Next, rinse it with a bit of water and conditioner if you still feel like you need it. As the hair dries you may still smell the vinegar, but the smell will dissipate as it dries.

Since no two heads are the same, you will need to play around a bit to see how much of a vinegar dilution you need. Start out doing this once or twice a week and see how it works for you. Good luck experimenting!
