The breeders where I got Bella pulled manes on their horses. When I got my girl she had a much thinner mane. I trimmed it to one length (because she had a major rub spot) and then let it all grow in the way it normally would grow. Here's a picture of her mane now. This is also with having used the MTG on the rub spot. It looks a little thin because I just sprayed it with mane and tail conditioner and brushed it, but it's so much nicer than it was when I got her.
