JAN: 4562261082400 Product Introduction: [Chemically Damaged Hair] Hair that has been altered by coloring and perms to enjoy fashion. [Environmentally Damaged Hair] Hair that has been altered by UV rays and air pollution. [Aging Damaged Hair] Hair that has been damaged further by thinning hair with less keratin and CMC, which changes with age. What these damages have in common is that the components of the hair are broken down and lacking. That is, keratin and CMC. Not just 'adding' them, but a Rikei treatment series packed with the technology to construct from the framework of keratin and CMC, which only Little Scientist can do. Born for women who enjoy fashion every day.
