The LLH vision
Products from the personal care world are artistic and technical compositions, that appeal to the imagination, subconscious and emotional side of each one of us.  They cannot be studied and analysed like other consumer goods.  LLH has therefore developed specific research methodologies, tailored to the needs of this universe.
To deal with these issues...
...LLH uses the following methodologies: Pre-recruitment of consumers or in-street recruitment, face-to-face, hall or in-situ tests (at home, point of sale...), telephone recalls, home placements and online studies.
...and has the following tools available to it: mailing lists of luxury and beauty product consumers in France containing over 15 000 contacts, CATI & CAWI and a statistical data processing program.
