In a laboratory test with live head lice, Shield products were
demonstrated to provide over 80% lice repellency.

Clinically collected live head lice were introduced into a sterile
environment, with treated and untreated tresses of human hair.
Three rounds of testing were conducted: A control with tap water
applied, a test cell with Shield Shampoo & Conditioner in 1
applied, and a cell with Shield Leave In Spray applied. Louse
movement was observed at a time interval of 4 hours.

P-values were obtained from paired t-tests between the number of lice
located on the treated vs. untreated tress. Any P value of less than 0.05
is considered a statistically significant difference.
