Add a splash of water, wash the gel out with the Lice Removal Shampoo in two rounds, then wash with your usual shampoo. Comb through with the metal lice comb to remove dead lice and nits. The first application takes about 47 minutes. Repeat the full treatment in 7 days to catch anything that hatched after round one. One kit treats one person.

8. Directions for use (use on dry hair)

Estimated treatment time, not including comb-out: approximately 45 to 55 minutes.

1. Apply gel (5 min) and wait (10 min). Apply Treatment Gel directly to dry hair, ensuring full coverage of the scalp and hair at the root. Use the enclosed applicator brush to spread the gel evenly and work it down to the scalp. Add a small amount of water if needed for full coverage. Wait 10 minutes.
2. Gently scrub scalp (15 to 20 min) and wait (10 min). Divide hair into small sections. Using the applicator brush, gently scrub each section with small back-and-forth and circular motions, reaching the scalp. Do not apply pressure to the scalp; the scrub and brush motion should be very gentle. Scrub 15 to 20 minutes. Once the full scalp has been treated, wait 10 minutes.
3. Remove gel. Add a splash of water. Apply half of the Removal Shampoo and massage thoroughly. Gently scrub hair down to the scalp (the brush may be used), then rinse thoroughly.
4. Final wash (optional). If hair is still oily, you may use your regular shampoo to cleanse hair as directed.
5. Comb out. While hair is damp, use the enclosed lice comb to remove any remaining lice and nits. Work in small sections. Wipe the comb on a tissue or rinse it frequently during combing.

9. After treatment and repeat treatment

• Repeat the full treatment in 7 days.
• If infestation persists after the second treatment, consult a healthcare professional.
• To reduce the risk of re-infestation, wash recently used bedding, hats, and hair accessories according to their care instructions and avoid sharing combs and brushes.

10. Storage

Store at room temperature. Do not freeze. Keep tightly closed when not in use. Clean comb and brush between uses by rinsing with mild soap and water. Wipe clean until there is no visible debris. Allow to air dry.

11. Adverse events and complaints

Possible adverse events: scalp itching, redness, dryness, or irritation may occur. Eye irritation may occur if product contacts eyes. Allergic reaction may occur in sensitive individuals (for example, rash, hives, swelling).

What to do: for irritation or suspected allergic reaction, stop use, rinse off, and seek medical advice if symptoms persist or worsen. For eye contact, rinse with water; seek medical advice if irritation persists. For ingestion, contact Poison Control or seek medical attention.
