How does Apple Cider Vinegar do this?

I've been using Apple Cider Vinegar after conditioning for some time and im still confused on how it gives my hair this manageable, shiny and soft look and feel. Every article online seems to say the same thing, "It lowers the pH of the cuticle which lowers it." But so do so many other things as well and they dont have anywhere near the effect that Apple Cider Vinegar has. What makes it do this, and how does it restore that natural texture and feel of hair?
