Products which discourage the transmission of head lice are appealing; however, few studies have tested this concept. This study aims to test the efficacy of four commercial products which claim to discourage infestation by head lice; MOOV Head Lice Defence Spray (MOOV), Wild Child Quit Nits Head Lice Defence Spray (Wild Child), 100% Natural Head Lice Beater (Lice Beater) or Lysout Natural Anti-Lice Spray (Lysout). An in vitro challenge test was used. Briefly, one half of a filter paper lining the base of a petri dish was treated with the test product. Lice were then introduced to the centre of the dish, which was covered and placed in the dark at 20°C for 30 min. The number of lice on the treated and untreated sides of the filter paper was then counted after 2, 4 and 8 h post-application. MOOV was significantly more effective at discouraging the transmission of lice than the water control (p < 0.01), while Wild Child and Lysout were not at all time points. Lice Beater was significantly worse than the water control after 2 h (p < 0.01), while there was no difference after 4 and 8 h. MOOV was found to perform significantly better than Wild Child (p < 0.05) and Lice Beater (p < 0.05) at all time points. It also performed significantly better than Lysout at 2 (p < 0.05) and 8 h (p < 0.05), but not 4 h. MOOV offers the best efficacy and consistency of performance of the four products tested to discourage the transmission of head lice.
抑制头虱传播的产品很受欢迎；然而，很少有研究对此概念进行测试。本研究旨在测试四种声称可抑制头虱感染的商业产品的功效；MOOV 头虱防御喷雾（MOOV）、Wild Child 防头虱防御喷雾（Wild Child）、100%天然头虱克星（Lice Beater）或 Lysout 天然除虱喷雾（Lysout）。采用体外挑战测试。简而言之，培养皿底部的滤纸一半用测试产品处理。然后将虱子引入碟子的中心，盖上盖子，在 20°C 的黑暗中放置 30 分钟。在应用后 2、4 和 8 小时后，计算滤纸处理和未处理侧的虱子数量。MOOV 在阻止虱子传播方面明显优于水对照（p<0.01），而 Wild Child 和 Lysout 则不然。Lice Beater 在 2 小时后明显比水对照差（p<0.01），而在 4 小时和 8 小时后则没有差异。MOOV 在所有时间点均明显优于 Wild Child（p<0.05）和 Lice Beater（p<0.05）。与 Lysout 相比，它在 2 小时（p<0.05）和 8 小时（p<0.05）时的表现也明显更好，但在 4 小时时则不然。MOOV 在阻止头虱传播方面提供了四种测试产品中最佳的功效和性能一致性。
