The Volume Duo combines regrowth stimulation with a natural hold effect — REDACTIV 2® to relaunch regrowth and anchoring, and Volumising shampoo to give body to fine hair.

Densify deeply, lighten on the surface: the targeted routine for fine, flat or limp hair.

Deep stimulation + light supportive effect on the surface.

  • REDACTIV 2® — Growth-reactivating serum lotion

    98% naturally derived · anagen phase

    Works on regrowth and anchoring — the fibre gains density at the root.

  • Volumising shampoo

    98% naturally derived · film-forming polymer · pea protein

    Light supportive effect that preserves movement and lightness, without weighing down.

  1. Volume wash

    2 to 3 times a week

    Lather the Volumising shampoo on wet scalp and lengths, massage, rinse.

  2. Serum application

    REDACTIV 2® · morning & evening

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

The Volume Duo addresses a dual need: truly densifying the fibre at the root via REDACTIV 2® stimulation, and making that density immediately visible thanks to the supportive effect of the Volumising shampoo.

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.
