I used the Nude Therapeutic Shampoo and Conditioner together. I have never used this line, but after several days use, I swear by it. My hair is very thick and often gets heavy due to the buildup other shampoos and conditioners leave behind. I never used to be able to use conditioner without my hair feeling limp, but the Nude Therapeutic Conditioner has completely changed that. I can even massage my scalp with this conditioner, and as long as I rinse well it moisturizes without causing any oily buildup. It also leaves my hair beautifully silky. The shampoo (while very effective) can cause my thick hair to feel tangled, and this instantly smooths and detangles it. I've never used the conditioner without the shampoo so I don't know how it would work on its own, but in combination it's fantastic. My only caution is that the shampoo comes out of the bottle a little thin and gives the impression that it won’t lather up, don’t let that fool you, it gets the job done and leaves you with a clean head of hair that feels full and is easy to style !
