These programs demonstrate HairClean's efficacy in killing live lice and lice eggs, its residual ability to kill live lice, and its ability to increase the ease of combing lice and nits out of hair. HairClean was tested on children, on hair samples, in-vitro, and was compared to other treatments including Nix and various home remedies.
The Effectiveness of HairClean Compared to OTC/prescription chemicals with 129 Children
Overall Results: More effective than most popular OTC and prescription chemicals HairClean 1-2-3, a non-pesticide spray based on natural active ingredients, was applied to the hair of infested children three times at intervals of 5 days. During each treatment spray was left on the hair for 15 min. The efficacy of HairClean was compared to an anti-louse spray sold in Israel and containing the most powerful over-the-counter and prescription chemicals currently available; 0.5% permethrin, 0.25% malathion, 2% piperonyl butoxide and 47.25% isododecane. A total of 940 children, 6-14 years old, from 6 schools in were examined for head louse infestation. 199 (21.2%) of the children were infested with lice and eggs, while 164 (17.4%) were infested only with nits (dead louse eggs or empty egg shells). 143 children were included in the study out of which 129 complied with the instructions for use. Children were randomly treated either with HairClean or the control pediculicide. Sixty children (92.3%) were successfully treated with HairClean and 59 children (92.2%) with the control pediculicide. No clinically detectable side-effects were seen in any of the children. In conclusion HairClean is a very effective pediculicide with no serious side-effects. Researchers agree that lice have become resistant to many pediculicdes, particularly permethrin and pyrethrins. However, in the group using the study's control pediculicide, 59 out of 64 children (92.2 percent) were successfully treated. This raises the question -- if lice are resistant to these substances, why did the control product perform as well as it did? Both Mumcuoglu and Meinking believe that its effectiveness may be due to the ingredient malathion, which has only recently been reintroduced against lice in the United States and Israel. Malathion is a prescription-only product in the U.S. because of its potential toxicity. Treatment Program With School Children Overall Results: 100% Effective Research Assistant Professor Terri Meinking of the Field Epidemiology Survey Team of the University of Miami School of Medicine was called in by the Monroe County Public Health Department (Key West) to develop a strategy to address a two year excessive head lice problem. The health department had been recommending treatment with margarine as a last resort method. Meinking, who is considered one of the worldís leading experts had been experimenting with HairClean 1-2-3 and suggested a field study using the product. Treatment was performed in the school to keep children from missing class. The school's 520 students were screened by professionals (Lice Source Services-Boca Raton, FL) and nursing students from the local Florida Keys Community College Nursing Program. Only those students identified with live lice or viable nits (lice eggs) were eligible to be included in the program. Thirty-seven students were eligible for the program. Participants were treated with HairClean 1-2-3 for 15 minutes, rinsed off, and shampooed with a baby shampoo. At the one-week follow-up, 8 had nymphs (baby lice from newly hatched eggs). One week later at the final evaluation, all students who followed the program were 100% lice-free. * HairClean 1-2-3 applied for 15 minutes to dry hair demonstrated 93.8% pediculicidal activity. At the one week follow up, eight of 32 individuals in the program had nymphs hatched out from eggs that survived treatment. Two individuals with lice at all stages were found to have infested siblings or parents that had not been treated. Infested siblings and/or parents that were not treated were contacted and were either treated or given products to be applied at home. At two weeks 29 of the 30 remaining volunteers, 96.7% were lice free (*one individual was most likely reinfested from other family members or friends). Comparison of HairClean 1-2-3 VS Nix and Olive Oil and Mayonnaise on School Children
Overall Results: HairClean was significantly more effective than the other treatments.
The purpose of the study was to (a)assess the efficacy of several treatments including home remedies, Nix, and HairClean 1-2-3 in killing head lice, and (b) test the feasibility of a school/community based head lice eradication program. Over 1,000 students and adults in Key Largo and Homestead were screened and 53 were eligible. Each participant was treated with mayonnaise, olive oil, Nix or HairClean and shampooed with a baby shampoo after the indicated time. The children assigned to the mayonnaise and olive oil groups were first treated overnight under a shower cap. They came to school the next day with hair still covered with shower caps. The hair was washed and rinsed and adult lice were found to be still active. These home remedies slow down the lice but require repeated overnight treatments and are difficult to work with. These children were switched to Nix or HairClean after the first overnight treatment. HairClean was applied for 15 minutes as per the directions and Nix was applied on damp hair for 15 minutes which is in excess of the directions. This was done because children had shown resistance to the directed treatment. The process was repeated a week later. HairClean was 98% effective, Nix 89%. The Pediculicidal and Residual Activity of HairClean 1-2-3
Overall Results: HairClean 1-2-3 was 100% effective at killing lice on human hair in vitro 100% of the additional lice added to the hair 24 hours after treatment also died demonstrating residual activity. Three grams of human hair were soaked in 30 ml of HairClean and then dried. 100 lice were added to the hair at an incubated temperature of 37 degrees centigrade. 100% of the lice died. Even when the lice were added to the hair 24 hours after the hair was treated. 100% of the lice died. By contrast, when the hair was treated with an ethyl alcohol solution as a control only 4% of the lice died. In-vitro Pediculicidal Activity on HairClean 1-2-3
Overall Results: 100% Effective The lice were dipped in HairClean for 15 minutes as per the instructions on the label. All were dead 1 minute after the rinse, and none recovered.
Ovicidal Activity of HairClean 1-2-3
Overall Results: HairClean killed 93.5% of nits. Human hair with lice nits attached to it was exposed to HairClean 1-2-3 for 15 minutes and then washed. After the treatment was repeated three times, 93.5% of the nits were killed. The Efficacy of HairClean 1-2-3 for the Removal of Head Lice From Human Hair
Overall Results: Combing lice from hair treated with HairClean is 10 times easier than from untreated hair. Hairs infested with head lice were obtained from infested children. A special machine then combed the hair with a fine-toothed comb. After treatment with HairClean, 51.4% of the nits were removed using this method compared with 5% for the untreated control group.
