All About Lice

Adult lice live roughly 30 days on the scalp and die within 1-2 days once they're off a host. Nits hatch in 7-10 days. Knowing those numbers tells you when to treat, how long to keep checking, and how much of the household cleaning actually matters.

Nits and dandruff get confused all the time — they're both small and white and found in the hair. Here's one quick test that tells them apart immediately, plus what else to look for if you're not sure what you're dealing with.

When your kid has lice at 9pm on a Sunday, you don't have time to second-guess the service you're booking. Here's what LiceDoctors' ratings, reviews, and 20-year track record actually show — so you can book with confidence.
