I am an Aveda certified hair stylist and this is one my favorite products from the whole line. It is used to nourish and control frizz for an all day smooth style. It gives the hair moisture without being heavy or leaving the hair feeling greasy. It's one of the only styling products that does not need to be blowdryed into the hair either so that's convenient. Even if your hair is curly or wavy it does not straighten the hair just eliminates frizz and leaves the hair more manageable and soft.
