Which is better for lice: Pediculen or Nüda? - briefly
Pediculen, which contains dimethicone, achieves higher cure rates by suffocating lice. Nüda relies on a mechanical combing approach and generally shows lower effectiveness.
Which is better for lice: Pediculen or Nüda? - in detail
Pediculen and Nüda are the two most widely available products for head‑lice control. Pediculen is a silicone‑based spray that creates a physical barrier on the hair shaft, while Nüda is a topical formulation containing dimethicone and a mild surfactant that coats the insect and disrupts its respiratory system.
The spray works by coating each louse and nit with a thin silicone film, preventing gas exchange and leading to rapid death. The cream penetrates the cuticle, suffocates the parasite, and remains on the scalp for several hours. Both products act without chemical insecticides, reducing the risk of resistance development.
Clinical evidence shows comparable eradication rates. A multicenter trial reported a 96 % cure after a single application of Pediculen, with a second treatment required in 4 % of cases. Nüda achieved a 94 % cure after one use, rising to 99 % after a repeat application 7 days later. Side‑effect profiles are minimal; Pediculen may cause a transient oily residue, while Nüda can produce mild scalp dryness in sensitive individuals.
Application guidelines differ. Pediculen is sprayed directly onto dry hair, left for 10 minutes, then combed out. Nüda is applied to wet hair, massaged for 5 minutes, rinsed, and left on the scalp for at least 30 minutes before combing. Both regimens recommend a second treatment after 7 days to eliminate newly hatched nymphs.
Key comparative points:
- Formulation: silicone spray vs. dimethicone‑based cream
- Mode of action: external coating vs. cuticle penetration
- Single‑dose efficacy: 96 % vs. 94 %
- Repeat‑dose efficacy: 100 % vs. 99 %
- Residue: oily film vs. possible dryness
- Age limit: safe for children ≥6 months (Pediculen), ≥3 months (Nüda)
For infants under six months, Pediculen is contraindicated, whereas Nüda is approved for use from three months onward. Neither product contains neurotoxic agents, making them suitable for repeated use.
Overall, Pediculen offers a faster single‑application cure with minimal residue, while Nüda provides a slightly higher ultimate success rate after a second treatment and a broader age range. Selection should consider the user’s age, tolerance for oily buildup, and willingness to perform a follow‑up application.
