Why this duo
Because results do not come from a single step.
The scalp and the hair fiber do not behave the same way and do not have the same needs.
This duo was designed to respect that reality to act precisely where hair begins and to preserve what already exists.
A thoughtful routine, without excess created to support hair over time rather than promise instant solutions.
