The Renaissance Treatment is the complete 4-month hair protocol. It brings together the three key products of the RENASCOR journey — REDACTIV 1® for early reconstruction, REDACTIV 2® for regrowth stimulation, and Densifying shampoo as a wash base throughout the journey.

Its logic respects the chronology of the scalp: a follicle should not be stimulated when its environment is degraded. Phase 1 — repair. Phase 2 — relaunch. Continuously — support fibre quality from the very first wash.

Three complementary treatments forming the complete chronology of the RENASCOR protocol.

  • REDACTIV 1® — Regrowth-activating serum

    Phase 1 · Early reconstruction

    Restores microcirculation, perifollicular inflammation and tissue quality before the stimulation phase.

  • REDACTIV 2® — Growth-reactivating serum lotion

    Phase 2 · Stimulation

    Acts on the anagen phase, anchoring and hair quality — without forcing the bulb.

  • Densifying shampoo

    Wash base · daily support

    Integrates the heart of the REDACTIV® complex — supports anchoring and fibre quality from the very first wash.

  1. Months 1–2 — Reconstruction phase

    REDACTIV 1® · daily

    Apply REDACTIV 1® morning and evening on a clean scalp. Wash with the Densifying shampoo 2 to 3 times per week.

  2. Months 3–4 — Stimulation phase

    REDACTIV 2® · daily

    Switch to REDACTIV 2® morning and evening. Continue with the Densifying shampoo 2 to 3 times per week to support the fibre.

The Renaissance Treatment supports the complete hair journey after chemotherapy. Over 4 months, it follows the natural chronology of the scalp — first restoring a stable follicular environment, then stimulating regrowth once the conditions are met.

The Densifying shampoo complements the action of the serums throughout the journey, with no break between phases.

Frequently asked questions

What you ask us
ask us most often.

REDACTIV 1 or REDACTIV 2 — how to choose?
REDACTIV 1 prepares a fragile scalp, post-chemotherapy or in the early phase of reconstruction: it repairs, soothes and prepares the biological terrain before regrowth. REDACTIV 2 takes over once regrowth is visible — it accompanies densification, hair diameter and resistance. Both care products share the same active base, the REDACTIV® complex, with a different formulation context depending on the scalp stage.
How long before results are visible?
First signs after 4 to 6 weeks. Density gains are measured every 30 days and reach their plateau around 90 days. A full routine lasts 3 months, renewable depending on the goal — densify, reinforce, or anti-aging maintenance.
Do your formulas contain minoxidil or a hormonal active?
No. No RENASCOR formula contains minoxidil or any hormonal molecule. The REDACTIV® complex acts on the follicular environment — microcirculation, perifollicular inflammation, hair anchoring, tissue matrix quality — without artificially forcing the bulb. No known rebound effect on stopping.
Which shampoo should I use during my routine?
The shampoo is part of the protocol. The choice depends on scalp condition: soothing by default (sensitive or under reconstruction), anti-dandruff in case of itching or dandruff, regulating on oily scalps, densifying or volumising on fine hair. A rotation between a technical shampoo and the soothing one is entirely possible.
Should I add a vegetable oil to the protocol?
No. Oils (castor, coconut, other fatty bodies) are not recommended on the scalp: they have no demonstrated action on regrowth and can disrupt scalp exchanges and sebum balance. For the lengths, our pea protein conditioner brings nourishing benefits without penalising the scalp.
