How to use
After towel-drying your hair, spread an appropriate amount between your palms and apply a thin layer, focusing on wavy or curly areas. For best results, use a hair dryer or hair iron to style your hair. The straightening iron firmly grips your hair for a smooth, lustrous straight look, while the curling iron securely wraps your hair for a smooth, lustrous curl. Please be careful not to notice any abnormalities on your skin. Discontinue use if you experience any of the following skin irritations. Continued use may worsen symptoms, so we recommend consulting a dermatologist. (1) If you experience any of the following symptoms during use: redness, swelling, itching, irritation, discoloration (white spots, etc.), or darkening. (2) If any of the above symptoms appear after direct sunlight exposure to the applied skin. Do not use on areas with cuts, swelling, eczema, or other abnormalities. If the product gets into your eyes, rinse immediately. Do not store in high or low temperatures, in direct sunlight, or out of reach of infants. As this product contains natural ingredients, variations in color and scent may occur, but this does not affect the quality.
