We do not recommend the AirAllé® treatment for children under four or for clients for whom the AirAllé® is contraindicated. In these cases, we recommend a strand by strand traditional comb-out to remove lice and eggs using only non-toxic products, followed by an application of our Active Rinse. With this treatment, additional combing and oil application are required to successfully complete the treatment process. You have the choice to purchase a professional grade nit comb and a bottle of Active Rinse to do the follow up treatment at home, or you can schedule a follow up comb-out to be done in the clinic on day 10. We do not offer our re-treatment policy for this service.
