Have you heard of Shapley's MTG?

I use it on my horse to promote hair growth (mane/tail as well as cuts/scrapes). And I've found that working it into her skin, also helps protect my hands from this dry climate. (I live in the southern part of NM.)

It's a little oily so after application you might want to crate Jet (or, if he'll tolerate it, put a tshirt on him) to protect your furniture, carpet, etc. MTG has a strange smell - it's not unpleasant yet it's not exactly welcoming either.

A 32oz bottle should set you back about $15.

Good luck!
