    Soft or hard water contains Ca and Mg salts especially in Hard water which make hair dry and harsh. Even it affects on formulation, tendency of Ca and Mg ions to form inorganic metallic salt with other ingredients which tends to lead instability of respective product. Deionistion removes such inorganic salts or reduce it to tolerable level.
