A note about going conditioner-only with hair....you generally want to only use conditioner that's 'cone free. Check the ingredients, anything ending in -cone is not something you want to use without shampoo. 'cones seal the hair, which is advertized as "locking moisture in", which it does, but it also locks moisture out, it works both ways. In order to get moisture back to the hair shaft you have to first strip the 'cone layer off, which is why shampoo is needed. Most shampoo contains, if I remember the word correctly, sulphates, which is a fairly harsh cleanser. From what I read I do not think herbal cleansers will remove 'cones. So the standard shampoo and then conditioner process of hair care is similar to refinishing a piece of furniture, say the dining room table. Instead of just wiping it down when it's dirty, you strip off the finish and then apply a new finish to it every day. Kinda silly, but that's how the normal western hair care process works. If you want to get out of that process, you use sulfates to strip the -cones one final time and then you stop using 'cones. With no 'cones then there's no need for sulphates, so all that's left is hair that gets cleaned with very gentle cleansers (herbal or baking soda or the stuff that's already present in conditioners) and hair that moisturizes readily since nothing is sealing things out. Be sure to check your other hair products as well for 'cones. Conditioner-only is another great hair care method. There are gentle cleansers in teh conditioner already and is very moisturizing, and as long as it's 'cone-free there should be no build up.
