My hair has always tangled badly too. I used to sit for nearly an hour combing them out after my daily shampoo. But for years, what I've been been doing is getting all tangles out before getting in the shower, then I wash carefully to limit the number of tangles I put in. Don't pile it on your head. I leave it hanging down my back and just wash the scalp and sqeeze a bit of the shampoo down to the ends, then condition, also carefully. Then I usually don't mess with it until it's dry.

I always tell them at the salon to be careful too, otherwise, they'll be spending for ever getting the tangles they made out and trying to sell me their conditioners like I'd never heard of such a thing.

Any conditioner with lots of Silicone, usually listed as dimethicone will make the hair smooth and slippery. But you'll probably have to wash the buildup out with a clarifying shampoo once in a while.
