I wash D's tail with reg shampoo and then I get a bucket and put some water and blech in it. Then stick his tail in the bucket and swerl(SP) his tail around and it comes out silky and white for horse shows
. I haven't gotten the brittle effect some people worry about but every horse is different. I also only have to blech his tail maybe once a month and pretty much never in summer since he has no mud to lay in lol.
