Hair reconstruction after chemotherapy: RENASCOR at TRIHOFEST 2026
In Minsk, at the first trichology festival of the Republic of Belarus, Stéphane PAULET, founder of Laboratoire RENASCOR, spoke to a professional audience on strategies and methods for hair reconstruction after chemotherapy.
A topic rarely addressed: the quality of regrowth.
TRIHOFEST 2026 brought trichology professionals to Minsk around advances in hair care. Invited as a speaker, Stéphane PAULET presented Laboratoire RENASCOR's approach on ground rarely covered at congresses: not whether hair regrows after chemotherapy, but in what condition — and how to prepare the scalp to favour dense, healthy, well-lived regrowth.
The presentation, delivered in English with simultaneous Russian interpretation, covered strategies and methods for hair reconstruction after chemotherapy: restoring the follicular environment — perifollicular inflammation, barrier function, microcirculation — before regrowth sets in. A reconstruction logic, presented to a practitioner audience.
The only speaker from France, Stéphane PAULET represented Laboratoire RENASCOR before more than 150 oncologists, physicians and trichologists from Russia, Kazakhstan, Belarus and Israel — an international stage for a topic still rarely addressed at congresses. Specialised since 2017 in hair reconstruction and reactivation, RENASCOR presented the REDACTIV® protocol, focused on the quality of regrowth after chemotherapy.
What was presented in Minsk.
Spontaneous regrowth is not quality regrowth. After chemotherapy, the follicle exits its blocking phase and regrowth most often restarts on its own. But its density, texture and scalp comfort are not guaranteed: that is where support matters.
The follicular environment determines the outcome. A scalp marked by treatment — perifollicular inflammation, altered barrier function, reduced microcirculation — offers unfavourable ground. Without restoring this biological environment, regrowth can be slow, weak or irregular.
Rebuild before stimulating. The logic presented reverses the usual order: rather than forcing the bulb, conditions for healthy regrowth are restored first, and action is taken early rather than passively waiting for regrowth to settle.
A clinical observation to support it. Stéphane PAULET shared a case presented at congress: a patient treated with anthracyclines and taxanes, with near-total hair loss, whose REDACTIV® support was accompanied, at four months, by markedly denser regrowth and a clearly improved fibre diameter compared to baseline. An illustration of the approach — presented as a clinical observation, not a promise of results.
