I place 1/4 teaspoon of citric acid into a full gallon of distilled water. Whenever I make my tea rinses, I do a 1/1 ratio of tea to this citric acid/distilled water combo. So say: 16 ounces herbal tea.... 16 ounces of the CA/Distilled water combo I hope thats not too confusing. I'll come back and do a tea rinse tutorial once I wake up better & have my coffee. LOL I have a kettle full of it thats been steeping overnight, so it's nice and strong by now. Citric Acid is a similar concept to ACV. It will balance the PH, close the cuticle leaving the hair with shine, and help remove soap scum from soapy cleansers. (black soap, or natural shampoo bars). So if you like ACV in your hair, you can use fhat instead. My scalp hates ACV no matter the concentration so this is a good alternative. Citric Acid can be found in Walmart near the canning/mason jars section. It's super cheap too.
