I have a horse (Canadian) with a naturally wavy tail. His mane sadly, was always straight... though since I purchased him 4 months ago, and have been feeding him biotin, flax, and using MTG, I've noticed that the underside of his mane is starting to get a very pronounced wave in it (finally!). So I have a few questions. First- do horses with naturally 'full' or wavy manes (genetically speaking) tend to develop fuller/wavier manes with age? (my horse is 5 in June) And, is there anything I can do to encourage more growth, fuller growth, and the natural wave he's supposed to have, beyond what I'm already doing? Thanks!
