Vinegar is good for removing build up and closing up hair cuticles. The vinegar also helps remove scaly build up. If the scales on your hair cuticles lay flat, that gives your hair the chance to be shinier. Apple cider vinegar is a good choice for trying this out. You can also use plain white vinegar.
