When you're booking lice treatment at 10pm after a stressful few hours, the word "guarantee" probably sounds good without you thinking too hard about what it actually means. Here's what LiceDoctors' 30-day guarantee covers, what it asks of you, and how it works in practice.
What the Guarantee Covers
Every in-home treatment from LiceDoctors is backed by a 30-day guarantee. If live lice are found after the treatment and you've followed the aftercare instructions your technician goes over before leaving, LiceDoctors will send a technician back to treat again at no charge.
The guarantee is there because the treatment works. A 99.6% success rate across more than 500,000 clients doesn't happen by accident. But lice cases are complicated by re-exposure, and the guarantee protects families in those situations.
What the Aftercare Instructions Involve
Before the technician leaves, she goes over a set of aftercare steps. Following them is what activates the guarantee if something comes up.
The main things involve basic household steps: washing recently used bedding and clothing on high heat, putting items that can't be washed in a sealed bag for 48 hours, and doing a follow-up comb-through at home a few days after the visit using a fine-tooth comb. The technician walks through all of this before she leaves and can answer questions on the spot.
One thing worth understanding: the guarantee covers live lice, not nits. A nit found after treatment that wasn't visible during the strand-by-strand check is different from a live bug. The technician does a thorough check before finishing, but hair length and density affect what's reachable in a single visit.
Why Re-Exposure Happens and What to Do
The most common reason a family sees live lice after a successful treatment isn't missed bugs — it's re-exposure. A child goes back to school or a sleepover, comes in contact with someone who has an undetected active case, and picks it up again.
Re-exposure looks almost identical to a treatment failure, which is why the timeline matters. Lice take 7 to 9 days to hatch from an egg and another 9 to 12 days to mature. If live lice turn up within the first week or two, they were likely there before or during the treatment. If they turn up three or more weeks later, re-exposure is more likely.
Either way, the guarantee applies as long as the aftercare instructions were followed. Call 800-224-2537 or book a follow-up through licedoctors.com.
Follow-Up Visits
If you want additional peace of mind after the initial treatment, follow-up visits are available at a reduced hourly rate. Some families book a check a week after the initial visit, particularly if the original case was large or if multiple family members were treated. The technician does a comb-through and confirms the case is clear.
This is optional. The 30-day guarantee covers the situation if live lice do show up, so a follow-up visit is more about reassurance than necessity.
HSA and FSA
LiceDoctors accepts HSA and FSA cards for both the initial treatment and any follow-up visits. A receipt with a diagnosis code is available for insurance reimbursement. This applies to return guarantee visits too.
