clarifying shampoo and add a conditioning agent or cationic polymer like polyquat 7 or honeyquat to it, we change it into a conditioning shampoo. If you're using a conditioner after washing, should we bother?
Yes! It doesn't take much to make a great impact - say up to 3% - but it makes a world of difference!
Have you ever washed your hair and felt it before conditioning? It can feel like straw, hard and scratchy, maybe a bit tangled. Adding a cationic polymer or dimethicone can make this feeling go away. You don't need much to make a difference, but I think it is an important inclusion in a shampoo. As well, we know that conditioning agents increase the mildness of a shampoo, which means our scalp will feel more moisturized and less irritated. We can also add dimethicone in low quantities - at up to 3% - to a shampoo to get some awesome conditioning action.
The downside of using a conditioning agent in a shampoo is that sometimes they can build up. Something like cationic guar gum can lead to build up on our hair, so you might want to use a clarifying shampoo - one without condtioning agents - once a week to remove it.
