The Post-Chemotherapy Duo is the starter pair of the RENASCOR protocol — REDACTIV 1® to restore a fragile scalp, and Dermo-soothing shampoo for daily hygiene without aggression.

It is the minimum base in the reconstruction phase: an active treatment and a wash base compatible with a sensitive, altered or early-regrowth scalp.

Two complementary treatments for the reconstruction phase.

  • REDACTIV 1® — Regrowth-activating serum

    99% naturally derived · reconstruction phase

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

  • Dermo-soothing shampoo

    97% naturally derived · sulfate-free

    Gentle hygiene base for sensitive, fragile or rebuilding scalps — usable even in the absence of hair.

  1. Gentle wash

    2 to 3 times a week

    Lather the Dermo-soothing shampoo on a wet scalp, massage gently, rinse thoroughly.

  2. Serum application

    REDACTIV 1® · morning & evening

    On a clean and dry scalp. A few sprays, massage with fingertips. No rinsing.

The Post-Chemotherapy Duo is designed for the early phase of the journey — when the scalp must first be restored before being stimulated. Stimulating a follicle when its environment is degraded is ineffective.

Once the scalp is stabilised, the transition to the stimulation phase is made with REDACTIV 2®.

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.
