If you are interested in trying to make something for yourself, you could watch a training video online such as the one from Beadaholique in the US
For me, kumihimo gives you the best results with horse hair.
The video gives you a really good idea of the basic technique on an 8 warp bracelet. When using horse tail hair I use 16 warps (group of hairs) for bracelets and 8 warp for necklaces and bracelets when beading.

8 warp bracelet with slate coloured seed beads
Still using horse hair I used three hairs per warp. That is 8x3 = 24 hairs approximately 50cm in length. All the hair is sorted after washing and placed in position on the kumihimo disk. The beads (in this case size 6 seed beads) are threaded in the chosen order.
Very quickly, as you work around the disk, the bracelet emerges.
Here is one I finished today.
