I have a lot of odds and ends of shampoo and conditioner lying around. When my Mom buys something to try and doesn't like it, she gives it to me. Then there are literally dozens of little hotel bottles I've accumulated over time. I like to switch them around. I think it works better that way.
I used to like Vidal Sassoon conditioner, and Mom gave me an old bottle a year or so ago, which I just finished. Next time I went to the store, I looked for more, but couldn't find any. Don't know if they no longer market in grocery stores, but it wasn't there.
However, I spotted something else I had heard of: "Mane and Tail" conditioner. I'd read about this stuff. It was originally used for grooming horses, then word got around that it did a great job on human hair as well. So I bought a bottle. Something like $3.59 for a quart. I've used it a couple of times, and it does a great job of conditioning my hair, leaving it shiny and tangle free.
It's a real animal product. The horse pictures on their website are amazing. I'd kill for hair like that...
Next stop: Mane and Tail shampoo.
The conditioner is a great product.
