The Nitty Gritty Aroma Therapy Head Lice Solution is applied directly to dry hair after detangling. Use a regular brush or comb to de-tangle your hair, then apply the solution to the roots and comb through, ideally with the Nitty Gritty NitFree Comb for effective results. Our solution helps the comb glide smoothly through any hair type, without foaming up like some hair conditioners. This allows you to see what you're doing clearly. The solution contains neem and wheatgerm, leaving the hair in good condition. It comes in a 150 ml size, suitable for 3 to 6 applications depending on hair length. The ingredients include Vitis Vinifera (Grape) Seed Oil, Triticum Vulgare (Wheatgerm) Germ Oil, Melia, Azadirachta (Neem) Seed Oil, Eucalyptus Globulus (Eucalyptus) Leaf Oil, Lavandula Angustifolia (Lavender) Herb Oil, Melaleuca Alternifolia (Tea Tree) Leaf Oil, Rosmarinus Officinalis (Rosemary) Leaf Oil, Pelargonium Graveolens (Geranium) Flower Oil, Helianthus Annuus (Sunflower) Seed Oil, and Tocopherol.
