The present study is set-up to compare in vivo clinical performance and safety of the test product versus an in the US commercially available, pyrethrum-based product (RID® shampoo). The study will be performed in subjects ≥2 year of both genders with confirmed diagnosis of head lice infestation. To support safety, local and global tolerability, skin and ocular irritation will be assessed and adverse events (AEs) will be registered.

Number of Subjects That Are Lice-free After 2 Treatments With Test Product (Including All Baseline Infestations).
Clinical efficacy is reflected by the % of subjects that are lice-free after 2 topical applications (at day 0 \& day 7 respectively) of the test product. In this analysis, all baseline infestations (mild, moderate, severe) have been included. Assessment is performed at study end (visit 4, day 10). A mild infestation corresponds to 5-9 lice and/or nymphs A moderate infestation corresponds to 10-24 lice and/or nymphs A severe infestation corresponds to 25 or more lice and/or nymphs
Time frame: Day10

Effect of Both Investigational Treatments on Pruritus (Local Tolerability Parameter), as Assessed by a Blinded Clinical Investigator.
The occurrence and degree of pruritus is rated by the blinded clinical investigator at each visit, using the following scores: none (best outcome), mild, moderate, and severe (worst outcome). None: the scalp does not itch; Mild: occasional episodes of itching, not bothersome; Moderate: frequent, several times a day, bothersome; Severe: nearly constant, frequent scratching, very bothersome.
Time frame: Day 0, Day 1, Day 7, Day10
Effect of Both Investigational Treatments on Scalp Excoriation (Local Tolerability Parameter), as Assessed by a Blinded Clinical Investigator.
The occurrence and degree of scalp excoriation (breaking of the skin, usually caused by scratching) is rated by the blinded clinical investigator at each visit, using the following scores: none (best outcome), mild, moderate, and severe (worst outcome). None: no broken skin on the scalp; Mild: one or two areas on the scalp on which skin is broken; Moderate: more than two separate areas of the scalp with broken skin but not generalized across the scalp; Severe: widespread breaking of the skin involving most of the scalp.
Time frame: Day 0, Day 1, Day 7, Day10
Effect of Both Investigational Treatments on Paraesthesia (Local Tolerability Parameter), as Assessed by a Blinded Clinical Investigator.
The occurrence and degree of paraesthesia (tingling or prickling sensation) is rated by the blinded clinical investigator at each visit, using the following scores: none (best outcome), mild, moderate, and severe (worst outcome). None: no tingling or prickling sensation; Mild: occasional tingling or prickling sensation; Moderate: frequent tingling or prickling sensation; Severe: nearly constant tingling or prickling sensation

Effect of Both Investigational Treatments on Skin Erythema (Local Tolerability Parameter), as Assessed by a Blinded Clinical Investigator.
The occurrence and degree of skin erythema (redness of the scalp) is rated by the blinded clinical investigator at each visit, using the following scores: none (best outcome), mild, moderate, and severe (worst outcome). None: no redness of the scalp; Mild: faint, barely perceptible erythema with limited distribution; Moderate: diffuse pink areas of scalp are readily visible; Severe: large areas of the scalp are red.

None: no lesions visible on the scalp; Mild: one or two lesions visible with crusting or other evidence of infection; Moderate: presence of more than two lesions with crusting or other evidence of infection, but not generalized across the scalp; Severe: lesions with crusting or other evidence of infection, involving most of the scalp.

Global Tolerability, Evaluated at Study End (Visit 4, Day 10)
Global tolerability is defined as the general well-being and comfort of the subjects. This parameter is assessed at day 10 in subjects, treated with either test product or reference product, respectively. The subject is asked to score his general feeling at study end and must provide a justification for his/her answer. Scoring was performed as follows: very good (best case), good, moderate, or poor (worst case).
