Whats the fastest way to get my horses mane to grow?

One way to make your horses mane grow longer and thicker is to protect existing growth by braiding or plaiting the mane. The type of braids described in this article to help grow a mane longer are commonly used by Arabian, Andalusian, and Friesian owners to help grow those long, flowing luxurious manes. (Even the Cavalia horses are braided in this manner when off-the-job!) This style of mane braid is also helpful for keeping your horse's mane low maintence.

At our farm, it's difficult to find the time to detangle broodmare manes, so on our mares prone to tangle we braid and band so we never have to fuss with combing witches knots and wind knots out of their manes. One small warning, the only drawback to this braid is that if a horse does decided to rub their mane while braided- they will rub an entire chunk out rather than a few hairs. So be sure an use some sort of anti-itch spray or cream on the roots of the mane to minimize excuses for rubbing!
