Introducing "Gyutto Corset Hair Milk," a texture-shaping hair milk that focuses on the "return of frizz" during the day.

Hair that's styled in the morning becomes frizzy again during the day—a new proposal that captures customers' experience as "frizzy hair returning."

"Gyutto" is a hair care brand that addresses hair problems such as roughness, frizz, and flyaways caused by damage, making it difficult to manage your hair as you'd like. The "Gyutto Corset Hair Mask," launched in 2024, is an in-bath care product that is easy to incorporate after shampooing, and has been purchased by many customers, with sales immediately after its launch being approximately four times higher than initially planned.
As we addressed our customers' concerns about frizz, we realized that even with nighttime care and morning styling, their hair would become frizzy, unruly, and difficult to manage during the day. We interpreted this customer experience as "frizz returning" during the day and used it to develop a new hair care proposal that addresses hair problems that change throughout the day.

A survey on hair concerns conducted by Rohto Pharmaceutical Co., Ltd. *3 revealed that 82% of women in their 30s to 60s, who are particularly concerned about frizz, experience their hair becoming frizzy again during the day. On the other hand, only 43% of those who use leave-in treatments to combat frizz during the day are satisfied, indicating that there are still unmet needs among users.
Our company wanted to create a product that not only addresses frizz from the core of the hair with in-bath hair mask care, but also cares for the "frizz return" caused by environmental changes throughout the day, aiming for manageable hair all day long. Therefore, we focused on the "frizz return" during the day and developed "Gyutto Corset Hair Milk," a texture-shaping hair milk that leads to manageable hair while having a light and smooth feel. This product is for those who are concerned about frizz during the day, those who are concerned about hair volume along with frizz, and those who want to maintain manageable hair with easy-to-use care. As an out-of-bath care product that is easy to use before blow-drying at night and before going out in the morning, it addresses hair concerns that change throughout the day.

*3: Survey conducted by Rohto Pharmaceutical Co., Ltd. in March 2026. "Experienced hair becoming frizzy during the day": Women aged 30-60, those with a high level of frizz concerns, n=160. "Evaluation of leave-in treatments for daytime frizz control": Women aged 30-60 who use leave-in treatments for daytime frizz control, n=44.

Product features

1. Equipped with our unique "Aqua Corset Technology *2" that focuses on the "rebound" of waves during the day.

   

   *4: PVP (repair component)
   *5: Potassium hyaluronate, lactic acid (repairing ingredients)

   Focusing on hair that has become prone to frizz and flyaways due to damage from UV rays, humidity changes, and dryness, we have incorporated our unique "Aqua Corset Technology *2".
   Potassium hyaluronate and lactic acid penetrate deep into the hair, repairing damaged hair. Furthermore, PVP coats the hair surface, leading to manageable hair from both the inside and outside. This dual approach of internal repair and external coating realizes "Texture Shaping Technology α," which tames hair that becomes frizzy and unruly over time.

2. A skincare-inspired formula that's easy to use even on hair that's frizzy from the roots.

   

   Developed with carefully selected skincare ingredients, this product is easy to use even near the roots where frizz *1 is a concern. It contains 13 beauty ingredients (moisturizing ingredients) *8 to hydrate the hair. Furthermore, it contains heat-protecting ingredients *9 to protect hair from heat damage from hair dryers, resulting in a formula that makes daily care a pleasant experience.

3. *8: Hydrolyzed keratin (wool), sodium lactate, 11 types of amino acids (betaine, PCA-NaPCA, serine, alanine, glycine, glutamic acid, lysine HCl, threonine, arginine, proline) (all moisturizing ingredients)
   *9: Gluconolactone, γ-docosalactone (all moisturizing ingredients)

4. Light and airy, yet naturally manageable.

   

   Many customers want to control frizz and volume while avoiding a heavy finish. To meet these customer needs, we've adopted a refreshing and lightweight milk-type formula. It blends seamlessly into each strand of hair, is non-greasy, and leaves a smooth feel. It's easy to use even for those concerned about heaviness, and leads to naturally manageable hair.

5. A subtle scent of green tea and pear.

   It has a subtle, refreshing scent that won't interfere with other hair care products or styling products.
