These shampoos are one that lather and foam with bubbles when using. They are designed for fine to normal hair, and for those who prefer more volume. Make sure the hair is very wet before applying, and after you've applied (start with a quarter size amount) then immediately add water to the scalp before you start to lather it up. The water will help spread the product. Scrub thoroughly all over the scalp using your finger pads, then once the hair is ready to be rinsed you MUST scrub your scalp while rinsing to remove it. If you don't do this, you may end up with a greasy root look and that's just left over shampoo still sitting on your scalp.
Think of shampoo's as scalp care, so these will mostly be used to cleanse the scalp when you wash your hair, and your conditioner takes care of the ends.
