Puressentiel Head Lice Treatment 2in 1 Shampoo effectively eliminates lice, larvae, and nits while leaving hair clean—all in one simple step. Its gentle formula, enriched with coconut plant oil, works mechanically by blocking the respiratory tracts of lice, ensuring they can't develop resistance. The nourishing, foaming base cleanses, soothes, and respects both scalp and hair. With its smooth, non-drip texture, the Treatment Mask Shampoo is easy to apply without running onto the face or into the eyes, making it a breeze to use. The result? Shiny, smooth, and easily manageable hair.
