I've never had a horse with little wispy forelock, but I've met quite a few that do. Is he a Thoroughbred? I've noticed it a bit more in Thoroughbreds, so just curious. I think some of it, is even if you don't realize it, when he eat, especially if the food is close to the fence, he's going to be kind of rubbing his head every time he puts his head down and picks it up, which won't help. I had good success with MTG on my Arabian's tail, but when I had my Thoroughbred (who DID NOT need any help in the mane tail and forelock area), and my first gelding, I used equus megatek rebuilder every time I gave them a bath (which was quite often), and I had great results. Sometimes though no matter what you try, genetically they just won't grow a good bunch of hair. Like me lol. I have very fine hair that won't hold a style, and gets scraggly looking pretty quickly, so even though I really wish I could have long hair, I have to keep it on the shorter end, besides the fact that it doesn't grow very long lol. He's a cute guy!
