An ethanolic extraction was done for the onion while a hot extraction process was used for the coconut oil. Their effects were individually tested on the parasite then compared with each other. Through purposive sampling, 150 samples are then acquired form children ages 7-12 years oldresiding in Burol Main, Dasmarinas. The results of the laboratory observation showed that both the onion extract and coconut oil have a parasiticidal effect on the human head lice. hence, it was found that the number of mortality of the head lice had no significant difference when the human head lice was subjected in onion extract and coconut oil. However, if the rate of reaction on the parasite is to be observed, it was shown that the onion extract had a faster reaction. Moreover, there was no significant difference between a pure and diluted onion extract.
