Why are NeutraLice Lotion, Spray and Advance Kits applied to dry hair?
Head lice breathe through special spiracles. They react to soaking with water by shutting down these spiracles. Applying a head lice treatment to wet hair is not recommended as it may reduce the effectiveness of the product. In the clinical studies conducted on NeutraLice the treatment was applied to dry hair and the kill rate was almost 98%.
