Nit Free Dimethicone Oil for Lice Treatment — 8 oz, 100% Pure, Thick Coating for Easier Combing

Nit Free 100% Dimethicone Oil is a viscous, silicone-based spray-on treatment that helps loosen and remove lice and nits by coating hair for simpler combing and removal.

Designed for home use on children and adults, this 8 oz bottle contains pure dimethicone formulated to provide a thick, even coating that aids mechanical removal of lice and nits. The formula is free from harsh additives and is intended to be used alongside a fine-tooth lice comb; many users pair it with the Nit Free Terminator Lice Comb for best results. The texture spreads easily through different hair types and remains viscous long enough to support an efficient combing session.

How does this product make lice combing easier?

The dimethicone oil creates a slick, uniform layer that reduces friction and helps nits slide off hair shafts during combing. That coating also helps separate individual hairs so the comb can pass close to the scalp where lice and nits attach. Because it’s thick, it stays in place long enough for a thorough combing session without constant re-application.

• Thick, even coverage that eases comb passage and nit release
• Reduces hair tangling for faster, less painful combing
• Works with all hair textures — straight, curly, thick, or fine
• Compatible with fine-tooth lice combs for detailed removal

Is this safe for children and adults to use at home?

Nit Free 100% Dimethicone Oil is formulated without harsh solvents or pesticides and is intended for family-friendly, at-home use. It does not rely on insecticidal chemicals; rather, it assists mechanical removal when used correctly. Always follow directions on application and avoid contact with eyes.

• Free from harsh additives commonly found in chemical treatments
• Simple topical application suitable for supervised home use
• Non-insecticidal approach; supports manual combing methods
• Follow label instructions and keep away from eyes and mouth

How should I apply the dimethicone oil for best results?

Apply the oil to dry or slightly damp hair, ensuring complete coverage from roots to ends where needed. Work in sections, comb with a fine-tooth lice comb after the oil has coated the strands, and wipe the comb frequently to remove captured lice and nits. Multiple applications may be required according to infestation level and family size.

• Section hair and apply a generous, even coating
• Comb close to the scalp with a fine-tooth lice comb after coating
• Wipe comb after each pass and repeat until no new lice appear
• One 8 oz bottle provides several full-head applications

Will it work on all hair types and ages?

The formula is effective across a range of hair textures and lengths because its mechanism is mechanical rather than chemical. It’s suitable for children and adults, and it spreads easily through thick, curly, or fine hair to enable combing. For best outcomes, pair the oil with a dedicated lice comb and repeat treatments as recommended to address newly hatched nits.

• Suitable for curly, straight, coarse, and fine hair
• Intended for both pediatric and adult use under supervision
• Helps make combing effective regardless of hair density
• Recommended to be used in combination with a fine-tooth comb
