EDU · PMR-GRT — Treatment System
An in-salon hydration system that re-establishes intra-fibre moisture balance and prepares the substrate for downstream chemistry.
Hydration is treated as a structural condition, not a finish quality. Grats restores the fibre's intra-cortical water and lipid balance so that subsequent treatments — colour, perm, restructuring — perform predictably.
Dry hair is not a cosmetic problem; it is a substrate that will distort the next protocol applied to it. Grats addresses that first.

Hoshitsu — Hydration
To restore intra-fibre moisture and inter-cellular lipid balance, returning the hair to a predictable substrate condition before further professional work.
Used as a preparatory protocol before colour, perm, straightening or restructuring services.
Deployed as a standalone hydration appointment when substrate condition is the primary concern.
Recommended in series for clients with chronic dehydration or environmental fatigue.
The system performs best when the substrate matches the following markers. Assessment is conducted at the basin before application.
C.01
Dehydrated cortex
Intra-fibre moisture below working range.
C.02
Lipid loss
Inter-cellular cement depleted by chemistry or wear.
C.03
Pre-service prep
Substrate due to receive downstream chemistry.
Diagnostic
Moisture and porosity recorded at the basin.
Hydration
Moisture-binding complex deposited under controlled dwell.
Lipid restore
Inter-cellular lipid complex re-introduced to the cuticle layer.
Equalise
pH and moisture normalised across mid-lengths and ends.

Cortical conditioning
Paired with a Paimore conditioner at home to preserve cuticle alignment.
Returned to assessment at each in-salon appointment; cadence adjusted to environmental load.
Recommended seasonally where humidity and temperature shifts disturb baseline moisture.
Indicated for dehydrated or environmentally fatigued hair, and as substrate preparation before any oxidative, reductive or thermal service.
