Well I just read your post again. One thing you mentioned is that you no-poo all the time. It could be that you may have product build up which aids in in tangles. Pantene is a conditoner that can build up on hair sometimes. So maybe you could clarify. But really the way I wash my hair affects wether or not have tangles more than the products, although they both work hand in hand. So if you are washing 11 inches of natural hair, and just massaging all the product in the hair can tangle while you wash. It works better for me to wash my hair while in big twists. Sometimes I take one twist down at a time to shampoo then I apply conditoner and twist it back up moving on to the next twist. Or sometimes if I am doing a conditoner wash I don't even take the twist down I just press the conditoner into eash twist, and then rinse when finished.
Also I have found that oil/conditioner pre-treatments help to keep shampoo, if I use it from being so drying, and also I don't get as many tangles.
Here's what I do:
Wash day
-make sure hair is in big twists
-wet twisted hair, add mix of oil/detangling conditoner
-put on plastic cap without heat for hour
-if I shampoo, take one twist down starting at the front of my hair and apply shampoo, rinse.
-add deep conditoner, twist back up
-when i get all the way to the back of my head, put my plastic cap on and let it sit for a while if I have time
-then with the conditoner still in take one twist at a time and detangle from end to root until all are down
-then rinse the conditoner out
-while my hair is damp i apply leave-in/oil, then style
I know you don't do twist, so you can section your hair and use hair clips to secure. Hope this helps if not, try a different conditoner. I happen to like kenra moisturizing for deep conditoning, biolage detangling is great at just busting up tangles, also jason naturals sea kelp is moisturizing, cheep, and 70% organic. Oh yeh, maybe your leave-in could be drying. I like ORS olive oil for a moisturizer, and shea butter for heavier moisturizer. By the way you can skip the shampoo if you really don't like to use it. Hope this helps.
