Clinical Studies

Rigorous clinical research has proven that NeutraLice Lotion and NeutraLice Advance are effective in killing head lice. In a study with primary school children conducted to international ICH-GCP standards, investigators at the University of Queensland1 compared NeutraLice Lotion and Advance to a leading lice treatment product.

NeutraLice products were applied three times, seven to 10 days apart exactly as per the instructions for use. The other product was applied twice as per the manufacturer's instructions. The results confirm that NeutraLice Lotion and Advance are almost 98% effective in KILLING head lice.

Product Treatment % KILL Rate
NeutraLice Lotion (Spray*) 3 treatments with a shower cap 97.62%
NeutraLice Advance 3 treatments 97.56%
Competitor product** 2 treatments 25.00%

In a follow up study2 NeutraLice Advance and NeutraLice Lotion were found to be effective in KILLING eggs. Prior to treatment at least 10 (live) eggs were removed from the head of each subject. Subjects then received a single treatment of one of the 3 products according to the manufacturer’s instructions. At least 10 treated eggs were removed from the head after the treatment. All of the eggs were held in an incubator for 14 days. The proportion of eggs which hatched after 14 days were compared for the pre-treatment and post-treatment eggs. The results showed that NeutraLice Advance killed 68.3% of eggs and NeutraLice Lotion killed 44.4% of eggs.
