"Hair Color by Numbers"

The last time we thought about pH levels, we were cramming for a chemistry exam. But it turns out that this acidity measurement may just be the key to long-lasting hair color.

Oribe Shampoo for Beautiful Color contains a mild blend of detergents at a pH between 4.5 and 6, so they'll clean and condition the hair without causing the cuticle to life up. This will prevent the color leaching that happens in products with a higher pH.
