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.
