PPt-Do shampoo and treatment is a salon-style hair care system that you can enjoy at home. Hair damaged from repeated use of hair coloring and perms have cuticle peels out and hollowed cortex. Proteins that are essential for healthy hair are lost. When using a high-class alcohol-based shampoo for ten times, the damaged portion of the cuticle remains and hair becomes unmanageable. Damaged hair remains in poor condition. On the other hand, with PPt-Do shampoo, the PPT adheres to and repairs the cuticle. After ten times usage, hair becomes shiny and silky.
