Moderate/severe case of head lice. Person was pretreated with a popular OTC pesticide. Over a hundred live bugs, nits and eggs were removed during treatment by Dandy Strands Head lice removal service LLC. 

Head lice eggs hatch approximately 7-10 (6-13 in some temperature climates) days after being laid.  Once hatched they are called nymphs. Nymphs go through 3 molting phases every 3-4 days becoming full adults able to mate and lay eggs up to 24 hours after the final molt.  Females have a "w" shape on the end of their body and stay pregnant after the.  A female adult louse can lay up to 5 eggs 2xs a day. 


Eggs are visible to the naked eye as soon as they are laid and are always the same size, They do not grow or move.. they do not slide easily off of the hair due to the cement like glue attaching them to the hair.  It is not possible to know if an egg(nit) is going to hatch unless you look at them under a microscope this is why all eggs must be removed.

Head lice themselves are not considered dangerous (although continuous studies are still being done to rule out whether they spread diseases.) However there are dangers that can occur with chosen treatments, secondary infections, pre existing conditions and people’s reactions. Here you will find a short list of dangers.
