Vinegar? daily hair products

First of all, I am looking for a product or mixture that is great for my simmental heifers overall hair. Also, want to be able to put this in daily or as many times as i get to wash her a week. ANYONE have any suggestions. I did some research and seen many people were putting vinegar in their mixtures. i never heard of this and was wondering what vinegar does for the hair.

This should help.

Vinegar removes scaly build-up and residue from hair shafts and closes the cuticles.   Since residue coats the hair causing it to look dull, removing residue gives your hair more shine.  By closing the cuticles, the hair slides more easily and there will be fewer tangles. Vinegar has a tonic action that promotes blood circulation in the small capillaries that irrigate the skin.

We use Vinegar with Kleen Sheen all the time. Little Russ Rag Oil and Bayrum are great. Bay Rum gives little set to the hair.
