It smells to me more like old fireworks (sorta like sulfur), and I like that smell, oddly enough, so it's ok for the smell. It also makes my hands really soft. *LOL*
What I recommend doing is just working it in at the roots of mane and tail, into the skin. Then you can use the residual to lightly work through the hairs with your fingers. I know with thin manes and tails, using combs is a bad idea, so you have to be careful, there.
I think putting it on once a week was fine for me, or after a bath if I wanted condition back on them, but you will have to bathe again as it attracts dirt and gets gummy/gross.
It works good for skin problems, too, and I rub some into a bald spot where they have scraped the hair off or had a small abrasion, or once a cut or scrape is healing to just past scabbing.
