Per the guidelines published in 2004 by the Colorado Department of Public Health and Environment, children who have had a head lice treatment “should not be excluded from school if nits are present (“no-nit” policies are discouraged). Nits found on the hair shaft more than a quarter inch from the scalp are likely already hatched or dead.”
So often we at LiceDoctors hear from parents that they feel that they should have known that their child has lice. "How did I miss it?", they wonder. As Denise, a mom in Troy, Michigan said to us last week, "I feel remiss somehow. Like, how how did both of my kids have it so bad and I didn't notice it?"
