My daycare called me with the news that my pre-K aged daughter had lice on a Friday afternoon. After buying $45 of over the counter remedies (Nix), I could not get rid of it. I called Kim at 7 PM on Friday night and she scheduled an appt for me the very next day. She thoroughly checked every head in my family and told me my options...my case was caught early so she said I could buy their all natural product and special comb and treat this myself or pay $175/head and have them do it. I opted for them to do it because I was just done with these bugs. They have a special hair dryer medical device that dehydrates the eggs,nymphs, and adults. The they thoroughly comb out the hair to ensure everything is out. I got a certificate for school saying my daughter was "nit free" and a guarantee for 30 days. If you are dealing with lice, this is the only place to go to have piece of mind...don't try to tackle this yourself with OTC stuff, it just doesn't work!
