Hair fragrance may be formulated around the needs of hair, while a skin perfume is assessed for its intended application.

An oil that feels comfortable on skin could leave unwanted residue in hair. A mist intended for hair may have different ingredients.

Check the label for permitted use areas rather than assuming that smelling similar makes two products equivalent.

Compare formats intended for skin, hair and other purposes, and understand why their directions differ. This guide offers general information and does not establish the ingredients, safety or availability of any unfinished XASIS concept. Use the exact finished-product details when buying or applying fragrance.
