It is the dry oil spray, the 'fresh' one. I only put it on the mane and tail, so it doesn't make the coat greasy & you don't have to bother with de-tanglers.
Yes it does work. I'm putting it on my SI mare's face, ears and forelock when she's in at night, the bits not covered by the Boett where I was seeing her rub. The rubbing's stopped now. When she's out being ridden, it goes on her mane and tail and they just look sleek rather than going greasy. Definitely worth a try... I'm using the dry oil spray
