Randomized Controlled Trial Comparing Efficacy and Tolerance of Four Pediculicides

Randomized Controlled Trial Comparing Efficacy and Tolerance of Four Pediculicides Acting Mechanically With Reference Product Acting Chemically (Prioderm)

THe main goal of our randomized controlled trial with blinded observer will be to compare four pediculicide products acting mechanically, Paranix Spray, Paranix Lotion, Paranix Mousse and Hedrin against a reference product acting chemically, Prioderm, during a non-inferiority (20% equivalence). THe randomization will be balanced every 10 families. The secondary objective will be to compare the lenticide efficacy of the products and their local tolerance and cosmetic acceptibility.
