Our densifying shampoo is the companion of the REDACTIV 2® phase, when regrowth is visible but still fragile, fine or uneven. Its 98% naturally-derived formulation cleanses without stripping and supports hair fibre quality.

It carries the heart of the REDACTIV® complex — apigenin, oleanolic acid, biotinoyl tripeptide-1, larix europaea and glycine — to support microcirculation, hair anchoring and tissue matrix quality from the shampoo onwards.

It does not artificially create volume: it improves the biological and mechanical conditions that allow the hair to gain in structure and resistance.

The REDACTIV® complex integrated from the shampoo, paired with hydrating and conditioning actives to preserve scalp suppleness and fibre quality.

  1. Wet the scalp

    Wet hair and scalp

    Under lukewarm water, wet the entire scalp and lengths.

  2. Apply & massage

    Apply and massage

    Place a hazelnut-sized amount in the palm, emulsify and massage the scalp for 30 seconds to activate microcirculation.

  3. Rinse thoroughly

    Rinse thoroughly

    Rinse with lukewarm water until fully removed. For optimal density, do not overload the roots with conditioner.

Our densifying shampoo is designed to accompany the REDACTIV 2® phase when regrowth is visible but still fragile. It acts as a protocol companion, progressively reinforcing the perception of density and hair quality, without aggressing the scalp.

It prepares the scalp and the hair fibre to allow REDACTIV 2® serum to act in optimal conditions. Density does not depend solely on the applied care, but also on the scalp environment and fibre quality.

REDACTIV 2® clinical study

Hair density visibly increases, month after month.

Randomised double-blind study conducted on 62 subjects presenting progressive and reactional hair loss, followed for 90 days. Phototrichogram measurement, cumulative gain every 30 days. Results illustrate the efficacy of the REDACTIV® complex — common base of all Renascor care.

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.
Can these care products be used during pregnancy or breastfeeding?
As a precaution, the use of REDACTIV care is not recommended during pregnancy or breastfeeding. Seek advice from a healthcare professional before any use. For other uses, REDACTIV is suitable for adults and children from age 3 (REDACTIV 2 — on hair longer than 1 cm).
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.
