How to use

Apply to dry hair before or after using a heat tool depending on desired effect: spray lightly over sections prior to styling to add hold while shaping, or mist over finished sections to set the style. Hold the can at a moderate distance from the hair and apply evenly to avoid local buildup. Reapply sparingly to reinforce hold on individual sections. Use with recommended heat settings for your styling tools and follow any safety instructions printed on the packaging.

Usage recommendations

For best results, style hair with the chosen heat tool in small to medium sections and set each section with a light mist of the thermo-setting spray. Allow the spray to cool briefly after heat exposure to stabilize the shape, and finish with a final light hold mist if additional fixation is needed. Avoid excessive application to prevent stiffness and residue.
