Lice Clinics does not recommend the AirAllé® treatment for children under four, or for clients who cannot receive the the AirAllé® treatment. In these cases, we recommend a strand by strand, traditional comb-out treatment to remove lice and eggs. Also, it is essential that you are only using our non-toxic products. This treatment option requires all of the following: an at-home comb-out kit, 30 minutes of combing every day for 10 days, an oil application on day 5 and day 10, and an in clinic recheck on day 11. We do not offer our re-treatment policy for this service.
