Nit Free 100% Dimethicone Oil for Lice — 16 oz bottle, thick family-safe coating for easier comb removal

Nit Free 100% Dimethicone Oil is a thick, family-safe silicone oil formulated to coat hair and help loosen lice and nits for easier comb removal.

This concentrated 16 oz bottle of pure dimethicone provides a simple, non-irritating option for at-home lice management. It’s designed to deliver an even, long-lasting coating that makes mechanical removal with a fine-tooth comb more efficient. Free from harsh insecticides and fragrances, the product focuses on smothering and suffocating lice mechanics while keeping the scalp comfortable. Use it alone or alongside a professional-grade comb for best results.

How does this dimethicone oil make combing out lice easier?

The oil forms a heavy, slippery layer on hair strands that helps loosen adhesive nits and immobilize crawling lice, so they slide up the shaft into the comb teeth. That reduces breakage and speeds up each pass with a nit comb. It also keeps hair smooth and manageable during repeated treatments.

• Thick viscosity ensures even coverage from roots to tips.
• Reduces hair tangling for gentler combing sessions.
• Extends work time — stays on hair during multiple comb passes.
• Pairs well with fine-tooth combs like the Terminator Lice Comb.

Is this safe to use on children and people with sensitive scalps?

Nit Free dimethicone is formulated without common harsh additives, making it suitable for family use when applied as directed. It is non-medicated and generally well tolerated, but a small skin patch test is recommended for very sensitive individuals. Avoid contact with eyes and follow rinsing instructions if irritation occurs.

• Free from insecticides, strong fragrances, and known irritants.
• Appropriate for repeated at-home applications.
• Recommended to test on a small skin area before full use.
• Rinse thoroughly if accidental eye contact happens.

How much product do I need and how often should I use it?

A 16 oz bottle supplies several full-head applications, depending on hair length and thickness. Typically one application followed by thorough combing is effective, with a repeat treatment as advised by your care routine or local guidance. The concentrated formula spreads well, so a little goes a long way.

• Short hair: one treatment per application; long or thick hair: more product needed.
• One bottle offers multiple family treatments.
• Reapply when combing shows remaining live lice or stubborn nits.
• Works best combined with a fine-tooth lice comb for full removal.

Will this leave hair greasy or affect styling?

The oil’s silicone base can leave hair smooth and slightly glossy until washed out; shampooing removes residue, and standard styling resumes afterward. For light styling between treatments, use small amounts and focus on combing rather than heat styling to avoid product spreading to tools. Residue washes out with shampoo and warm water when treatment is complete.

• Creates a temporary glossy, conditioned finish.
• Wash with shampoo to remove oily residue after treatment.
• Minimize heat styling while the oil remains in hair.
• Safe to use before school or activities if lightly applied.

Who is this for: Nit Free 100% Dimethicone Oil is intended for families, school-aged children, and adults seeking a non-chemical, easy-to-apply option to assist mechanical lice removal. It’s suited to all hair types and especially helpful when you want a gentle, repeatable at-home approach that pairs well with a fine-tooth lice comb. Choose this 16 oz bottle when you need enough product for multiple treatments and prefer a formulation free of harsh fragrances or insecticides.
