Insights
A new coconut-derived emulsion (CDE) shampoo effectively treated head lice in children. Continued use as a cosmetic shampoo helped prevent re-infestation.
Area of Science:
- Dermatology
- Parasitology
- Pediatrics
Background:
- Head lice infestation is a common pediatric issue.
- Existing treatments have varying efficacy and resistance concerns.
Purpose of the Study:
- To assess the effectiveness of a novel coconut-derived emulsion (CDE) shampoo for treating head lice in children.
Main Methods:
- A school trial involving two treatment applications and a family trial with multiple applications or cosmetic use.
- Evaluated UK school children and families in Northern Somerset.
- Primary outcome was the number of children free from infestation post-treatment.
Main Results:
- The CDE shampoo achieved a 61% cure rate in the school trial, compared to 14% for permethrin.
- In the family trial, a 96% cure rate was observed when all members were treated.
- Cosmetic use of the CDE shampoo after treatment reduced re-infestation rates.
Conclusions:
- Coconut-derived emulsion shampoo presents a novel and effective strategy for managing head lice.
- Its use as a cosmetic shampoo can contribute to reducing the recurrence of head lice infestations.
Objective:
To evaluate a novel coconut-derived emulsion (CDE) shampoo against head lice infestation in children.
Design:
A school trial in which pupils were treated on days 0 and 7 and checked on days 8 and 15 and a family trial where product was applied by parents three times in 2 weeks or used as a cosmetic shampoo and checked on days 14 and days 70.
Setting:
UK schools in Bristol and Western-super-Mare and families in Northern Somerset.
Main Outcome Measure:
Numbers of children free from infestation after treatment.
Results:
In the school trial, percentage cures at day 8 were 14% (permethrin, n=7) and 61% (CDE, n=37). In the family trial where all family members were treated, cure rate was 96% (n=28), and if the shampoo was subsequently used as a cosmetic shampoo, only 1 of 12 children became re-infested after 10 weeks.
Conclusion:
CDE shampoo is a novel effective method of controlling head lice and used after treatment as a cosmetic shampoo can aid in the reduction of re-infestation.
