The Cowboy Magic Detangler & Shine works, well, magic on Whisper's tail. Though I work on it daily, Whisper's tail is prone to dreadlocks and snarls, and its overall texture is rough and coarser than a typical horse's tail. Not pretty. With this awesome product, though, it just takes a little bit - maybe a teaspoon or a little more - rubbed into the top of Whisper's tail to completely change its texture. I work the product in with my hands and then start brushing from the top down, and the snarls and knots just disappear. Whisper's tail is left with a soft, sleek feel - no more of that coarse and brittle texture - and it looks healthier overall. I use this product every 3 or 4 days to keep Whisper's tail soft and smooth.
I really like the Detangler & Shine because it doesn't contain silicone, which can dry out your horse's tail even more. Instead, this product conditions your horse's tail in a way that you can both see and feel. At the same time, it doesn't leave manes or tails as sticky dirt magnets, like some other products do. Your horse's mane and tail are silky and soft, and the shine that this product brings out makes your horse look truly impressive.
If you're planning to use the Detangler & Shine, don't do so right before a horse show; your horse's hair will be so slick that braiding will not go well. However, I'd definitely use it a few days before, since its effect lasts and makes detangling manes and tails a breeze.
Lastly, you really can't beat the price. Available in 4 ounce, 16 ounce, and 32 ounce bottles, you can purchase just what you need. The 16-ounce bottle starts at $7.99 at Dover Saddlery; you'll have a hard time finding a quality grooming product for less.
