The SalonPro features 30 rollers in 4 assorted sizes provide complete styling versatility for creating any of today’s hair styles, and non-damaging steam conditions the hair as it locks in curls. Because there is no damaging heat, you can use the Caruso SalonPro Steam hairsetter as often as you like.  Great for all hair types, and will help you create healthy, strong, beautiful curls with added body and shine. Achieves the 30 second curl by blow drying hair first to evaporate moisture   The Soft foam rollers are infused with gentle steamed moisture. Hair is then wrapped on the infused roller and covered with a shield. The Patented roller and shield design creates even moisture penetration and allows airflow for quick evaporation, or speed the process with a hair dryer. Gentle moisture penetrates the hair’s molecular core allowing it to relax and bend. As moisture evaporates, hair is set in curled position. The molecular hold is so strong, it can only be released by shampooing.  Creates perfect spiral curls & waves and curls last for days.
