I’m the only person who hates Healthy Hair Care Horse Moisturizer, I guess. I followed the directions on the bottle to the letter and just barely sprayed my horse with it, but it still left an oily residue on him. Since he’s a grey, he immediately went out and rolled, turning himself into a dirt ball.
Since then, I’ve used Vetrolin Shine on him. It helps to keep him clean, I love the smell, and it doesn’t seem to dry out his coat, mane, or tail. YMMV.
