The present study is set-up to compare in vivo clinical performance and safety of the test product (X92001752) versus 3 other pediculicides (2 medical devices and 1 conventional pesticide).
The present study is set-up to compare in vivo clinical performance and safety of the test product versus a) RID Super Max Solution (oligodecene oil), Nix crème (1% permethrin), and Pouxit Végétal (fatty acid salts). 220 subjects (n=55 per treatment group) with confirmed diagnosis of head lice infestation will be included. To support safety, local and global tolerability, skin and ocular irritation will be assessed and adverse events (AEs) will be registered.
