Difference Between Ion & Molecular Caruso Molecular Hairsetters


    • The difference between ion and molecular Caruso Molecular Hairsetters starts with the water used to create the steam that activates the rollers. Once water is added to the heating component, users of ionic units add a special powder containing sodium chloride. The powder increases steam production and produces longer-lasting curls that are less frizzy. Water additives are not required with molecular units, but according to users, distilled water produces more steam and reduces mineral deposit buildup on the device due to a lack of impurities.

    Chemical Reactions

    • Ionic units rely on water being heated through a series of energy transfers via chemical compounds included in the company's water addictive, like sodium chloride and ammonium persulfate. The water heats faster and produces more steam. Molecular units agitate the molecular structure of water, causing an increase in temperature that eventually results in steam.


    • According to retail sites at the time of publication, the Caruso Ion Hairsetter is only available in professional size with 30 rollers. The Molecular Hairsetter is available in two sizes: professional and travel. Travel hairsetters perform the same as professional units, but come equipped with 14 rollers instead of 30 for greater portability.


    • Some ion hairsetter customers have complained of a loud beeping noise that occurs while the device is being used. A complaint among molecular device users is reduced steam output. Ionic units appear to have a shorter shelf life than their molecular counterparts, with a number of customers indicating that their unit stopped working anywhere between three uses and four months. On average, faulty molecular units had operational issues approximately nine months after being used two to three times per week.
