I am not sure if this was just my imagination but I swear I got red highlights from using ACV as a conditioner. My hair is light brown, some people call it dark blond but I don't think it's blond. Anyway, I hated the red highlights and I started using rice vinegar (it's yellow). I think my hair got some blond highlights from it and many people actually commented on my hair colour. Do you think vinegar can change highlights on light hair? Of course, the ends of my hair are light than the roots (I don't apply vinegar to the roots) but that's normal for all people with light hair I've seen. And do you think it can make hair more wavy? Sorry if that's a stupid question, I just wonder if it's worth continuing with the vinegar rinse or it's all in my head.
