If you can't be with the comb you love, use the comb you're with.
specialty lice combs on this blog because combs designed for the task of lice and nit picking - combs with long, rigid, tight metal teeth - save you a lot of time. But what if you don't have access to an actual metal lice comb? Grab the comb you do have. If it has teeth that are narrow and close together (i.e. not a hair pick), it can still have some effectiveness. The more rigid the teeth the better. Wet, condition, and detangle the hair. Then start combing. If you have large egg-laying bugs on your head, you should still be able to comb out a lot of them out. This is still progress. Get the better comb when you can but for now, just get busy.
