Intra-Cortex™
Extreme damage, post-chemical, lost elasticity

Extreme damage calls for a sequence. Reconstruction in three steps.
Structural rescue system for chemically damaged, porous hair with compromised elasticity. Step 1 equalizes porosity and contracts the scale opened by chemical services. Step 2 removes the residue that blocks the reconstructor's entry and levels the fiber. Step 3 deposits the highest protein load in the line: Hydrolyzed Keratin, Soy and Wheat proteins and marine Cystoseira extract.
Diagnosis · indicated for
- Hair that stretches and does not recover in the elasticity test
- Uneven porosity along the length
- Breakage when combing wet
- Post-lightening, post-color, post-transformation
Action front
Cuticle and outer layers of the fiber. The porosity equalized in Step 1 is the condition for the Step 3 deposit to act evenly along the length.

Intra-Cortex 3-Step Rescue · 40 to 50 min
- STEP 0 · DIAGNOSIS · ELASTICITY AND ABSORPTION TESTElasticity on a wet strand: stretches too far and does not recover, reconstruction; breaks without stretching, reconstruction with an end trim. Water absorption on a dry strand: absorbs within seconds, high porosity.
- STEP 1 · RESET · CORTEX RESETOne pump on washed, damp hair, applied evenly from lengths to ends. Massage and rinse.
- STEP 2 · CLEANSE · CORTEX PREPTwo washes, one pump in each. Massage and rinse. Delivers a clean fiber with leveled porosity, ready to receive mass.
- STEP 3 · REBUILD · CORTEX REBUILDOne pump on lengths and ends, precision gloving. Processing time according to the diagnosis (reference: 10 to 15 minutes, optional moist heat). Heat sealing with dryer and blow-dry. Rinse according to the protocol.
- FINISH · CORTEX SHIELD + CORTEX GLAZECortex Shield on damp hair, dryer and blow-dry. A few drops of Cortex Glaze on lengths and ends as the final step.
“We replaced the mass that chemical services consumed. Intra-Cortex maintenance at home keeps porosity leveled until the next protocol, in 30 days.”
Result
Elasticity restored and resistance to combing right at the backbar.

Reconstruction continues after the chair.
Five instruments that maintain the result of the three-step system: sealing, weekly protein infusion, shock dose, heat protection and polishing. Together they form the home care prescription for reconstruction and the backbar booster kit.

Diagnosis · indicated for
- Maintenance after the three-step system
- Hair that loses body between services
- Dry, dull ends after treatment
- Transformation client who needs a protein routine at home
Action front
Cuticle and outer layers of the fiber. The mask and ampoule replenish mass between protocols; the leave-in and serum protect the rebuilt mass from heat and restore the shine that porosity scatters.

Intra-Cortex Maintenance Schedule · 30 Days
- WEEK 1 · SALONThree-step system (Cortex Reset, Cortex Prep, Cortex Rebuild). Finish with Cortex Shield and Cortex Glaze.
- WEEKS 2 TO 4 · HOMECortex Prep at every wash. Cortex Infusion once or twice a week. Cortex Seal at the remaining washes. Cortex Shield before the dryer or flat iron.
- BACKBAR BOOSTER · SALONCortex Boost under the mask, or Keratin Shock (Backbar Lab) for 3 to 5 minutes, at any in-between appointment.
- DAY 30 · REASSESSMENTNew elasticity test. Repeat the three-step system or move to the maintenance line indicated by the diagnosis.
“The salon reconstructor deposits the mass; the home routine keeps the fiber from emptying out again before the next protocol.”
Result
Porosity leveled and mass preserved until the next protocol.
