Someone, sorry I don't remember who and I have given this recipe several times, posted this
1/3 ac vinagar
Mixed in spray bottle and applied to tail dock for hair growth.
I use the MTG but plan on trying this in the spring. Vida's hair grows fine but she has terrible dry flaky skin on her tail.
They also said you could add baby oil to this mixture for added moisture, but I think lanolin would work better.
