Introducing New UL•OS Scalp Shampoo Volume-up
Addresses men's scalp condition and hair problems

Otsuka Pharmaceutical Co., Ltd. (Otsuka) has announced the launch of UL•OS Scalp Shampoo Volume-up, a new addition to the UL•OS line of men's total body skin care products based on the pharmaceutical-based concept of Cosmedics*1 for healthy skin. Focusing on concerns about hair volume, texture and resilience, new UL•OS Scalp Shampoo Volume-up will be launched nationwide in Japan on March 13, 2023.


In an Otsuka survey*2 of men in their 30s through 50s, one in three respondents indicated that they are troubled by insufficient hair volume, while one in five are concerned about the texture and resilience of their hair. These concerns are more pronounced among men over 40 years of age.

UL•OS Scalp Shampoo Volume-up was developed to address these concerns. Its rich lather gently cleanses an oily scalp without overstressing the hair. To address concerns about texture and resilience, which increase with age, three active ingredients*3 reinforce hair*4 from within and without. Strongly boosting hair shafts from the roots, application of unique coacervation technology*5 gives hair a soft and airy finish without needing to use a separate rinse. Addressing volume, texture, and resilience, new UL•OS Scalp Shampoo Volume-up fosters healthy scalp and hair condition through daily shampooing.
