- Medium hold body-building heat-activated spray. Formerly known as Beyond Body Thermal Spray. What it is: Non-aerosol, heat-activated spray. Innovative formula seals the cuticle and adds body, shine and light control. Why you should use it: Delivers exceptional shine when used with a flat iron, curling iron or blow dryer. Shields the hair from thermal damage. Protects the cuticle against excessive moisture loss and styling stress. Creates a humidity resistant barrier to control the hairstyle in high humidity conditions. When you should use it: Designed to be used on either clean, dry hair or hair that has been freshly styled with an Aquage styling product. How much to use: Depending on the thickness and length of the hair, spray on both the top and bottom sides of the section from roots to ends until total coverage of the section has been achieved. Spray from far enough away to avoid making the hair section wet. How to use it: Spray in quick, short bursts from about 8 to 10 inches away from the hair, directing the spray toward the ends. Press and run fingers down the section to distribute product evenly from roots to ends. When styling with a ceramic flat iron, work on sections that can be easily managed, no more than 2 inches wide and ¼ inch in depth. Begin pressing at the roots and work toward the ends in a smooth, fluid manner until a smooth texture and the desired level of body is achieved. Repeat the technique if the goal is to increase the level of hold and control on each section.
