During the course of a 30-minute treatment, the trained AirAllé technician will gently place the device's applicator tip under the hair and against the head, moving its position every 30 seconds until the entire head has been treated.
The AirAllé device blows heated air through its applicator tip along the scalp and hair shafts at a higher flow (but much cooler temperature) than a hair dryer.
The AirAllé technician will stop the use of the device immediately if an individual being treated gives a verbal or physical sign of discomfort.
Because the purpose of the AirAllé device is to kill the lice and eggs through dehydration (and not to blow them out of the hair), dead lice and dead eggs will remain in the hair after treatment. AirAllé technicians will do a post-treatment comb-out (which usually takes 30 minutes) with a good quality lice comb to remove the dead lice and eggs. Most technicians will then apply a post-treatment rinse using dimethicone oil to kill any remaining hatched lice that may have survived the treatment.
