Review of egg-removal abilities of commercial products

A new study investigates the ability of commercial head lice products to remove eggs from hair.

The study by Ortega-Inssaurralde et al., published online in July 2014 in Parasitology Research, compares several commercial formulations of head lice products to see how well they loosen eggs from the hairs to which they are attached.

The study found that cream-based and dimeticone-based products had the best egg-removal effects; whereas gels and lotions - even those marketed specifically as egg-removing - were no better than the control.
