Yeah, I really like it. I've experimented with it on his tail (the ends are bleached out) and it looks really natural. The white on his legs are covered completed when I used another layer (I only did one for the after photo). The only problem is that my horse hates me putting it on, lol. He'll have to get use to it.
I don't use that exact one but I have a white and a black spray for touch ups before shows. Its great stuff. As said, spray it on and leave it for a bit then brush out. After that I spray on some hair shine spray and it comes up a treat
