This is the Missha Pro Cure Trans Style Holding Hair Spray. It is a hair spray with excellent setting power, and since it contains hydrolyzed keratin and Abyssinian kale seed oil, it also moisturizes the hair, so it is a product I use well.
Personally, I have repurchased this product several times because the effect lasts a long time if you spray it several times and touch your hair after it has cooled down following a straightening treatment.
