gray hair care from "concealing" to a positive "beauty routine."
September 30, 2025
ROHTO Pharmaceutical Co., Ltd. (Headquarters: Ikuno-ku, Osaka; President: Hidetoshi Segi) will launch "Prolee Repair Color Treatment," a color treatment that improves shine while correcting frizz and gray hair *2, from its hair care brand "PRORY," PRORY advocates "Science that challenges hair aging*1." Sales will begin sequentially from October 1, 2025 (Wednesday) on Amazon, Rakuten, and the official Rohto Pharmaceutical online store.
In response to the sharp increase in gray hair concerns among those in their 40s, we propose a new approach to gray hair care, evolving the perception of gray hair care from "hiding" to "a positive beauty habit," while bringing out the natural beauty of the hair. "PRORY Repair Color Treatment" employs our unique "Even Color Protein Formula," which corrects frizzy gray hair *2 while improving color retention, delivering new value to gray hair care.

Background of release
Gray hair problems increase sharply from the age of 40.
According to a survey on hair concerns (Rohto Pharmaceutical, January 2024, women aged 30-60, n=30,000), the percentage of women troubled by "gray hair" increases sharply from 32% to 61% in their 40s, becoming the most common hair concern. This trend continues with age, reaching 73% in their 50s and 60s, indicating that gray hair is a long-term issue. On the other hand, concerns such as "lack of firmness and elasticity" and "lack of volume" also increase with age, indicating that hair concerns are becoming more complex. (Lack of firmness and elasticity: 12% in their 30s → 17% in their 40s → 20% in their 50s → 24% in their 60s; Lack of volume: 11% in their 30s → 15% in their 40s → 18% in their 50s → 25% in their 60s)
Color treatments are becoming an increasingly popular option for gray hair care.
In addition to hair dyes and hair coloring, the demand for "color treatments" is expanding as a means of caring for gray hair. Color treatments are appreciated for their ease of use and minimal burden on the hair and scalp, making them a popular choice, especially among busy modern women in their 40s to 60s.
However, a survey (Rohto Pharmaceutical, 2023, women aged 40-60 who use color treatments, n=619) revealed that there are still issues with satisfaction with current color treatments.
- Only 38% of users were satisfied with the color retention, the lowest rating among all users.
- Only 56% were satisfied with the "beauty of the finished hair color," and it was found that many users were dissatisfied with the basic functions and performance of color treatments, such as color retention (38%) and hair color and shine (58%).
In particular, regarding the "beauty of the finished hair color," one of the reasons why "wavy gray hair *2," which becomes noticeable after the age of 40, is difficult to dye is said to be. To solve this problem, it is necessary to not only care for the gray hair but also to approach the inside of the hair.
Our unique "Even Color Protein Formula" technology brings new value to gray hair care.
To address this challenge, "PRORY Repair Color Treatment" employs a unique "Even Color Protein Formula" that approaches frizzy gray hair* 2 from both a repair and moisturizing perspective, while also improving color retention. It repairs hair damage, smooths frizzy gray hair *2, and leads to a beautiful finish for the entire hair. While conventional gray hair care has been seen as a "negative grooming task to be reluctantly hidden," this product evolves gray hair care into a "positive beauty habit," proposing a new approach that cares for gray hair while bringing out the natural beauty of the hair.
