I use Mane & Tail Shampoo & Conditioner, faithfully now for the past 12 years. Yes, it is a shampoo for horses, but humans can use it too. Here is their site: manentail.com/ .

When Anya and I went to Costa Rica, I left my Mane & Tail at home & couldn't find it at her walmart. It is usually by the pet shampoo area, lol, yes, it's true. So I bought some Infusium 23 Shampoo & Conditioner. infusium.com . I really like the Infusium Product, but noticed after a few shampooings, it felt like there was some build up on my hair ... with the Mane & Tail product, it usually takes a couple of months before my hair feels that way. When that happens, I simply use a white vinegar rinse on my hair before shampooing. 1/4 cup white vinegar to 1 gallon cold water... it will remove product buildup like a dream!
