Research Scientist in Hair Biophysics - L’Oréal - Wizbii

Research Scientist in Hair Biophysics


Description de l'offre

L'Oréal's Research & Innovation

Inventing beauty so is L'Oréal‘s vocation. Since its creation by a researcher, one century ago, the group has consistently believed in research, pushed back scientific boundaries and knowledge, increased innovations and patents, with a taste for exploration and quality obsession.

Beauty is a scientific adventure and there's no innovative product without progress and knowledge.


The candidate will be responsible for proposing, carrying out and managing scientific research projects and collaborations in the hair physics and nanophysics domain, aiming at understanding our cosmetic targets (hair) and designing new technical solutions. One of the foremost tasks of the candidate will be to understand and help translating consumer expectations into technical challenges and to specifications in terms of raw material and/or systems with high performances through experimental approaches. The candidate has to develop knowledge on hair biophysics science, identify new targets and concepts to repair, protect, restore and transform the hair fiber.


The candidate will integrate the Hair Biophysics Group in the Physics Department of the Advanced Research Division of L'Oréal R&I, under the responsibility of the Group Leader.

This team is in charge of developing and using new tools and approaches to explore new research territories on hair science which aims at :

(1) decoding what should be the hair biophysical properties of a cosmetic product hair for a given final performance

(2) proposing accordingly new innovative raw materials design or concept

(3) characterize the performance of existing raw materials or systems for a better transformation and valorization. All these aforementioned tasks require working in a multidisciplinary environment. The group is interfaced with clinicians, physicists, physico-chemists, raw materials providers, biologists and formulators (Applied Research), since our approaches are multi-scale from decoding global cosmetic performance down into local mechanistic hair targets .
