1. Breathe. So, you might have head lice. So what? You'll be fine. Even if you are on your own, you have what it takes to beat this.
2. Get a good metal lice comb. Now, not all metal lice combs are created equal. Some still have pretty bendable teeth and you need a comb with rigid teeth. Check here for some options. When you are getting the lice and bugs out of someone else's head, a proper comb is very helpful. When you are removing the lice from your own head, it is almost essential. (Note: If there is no way you can get a good metal lice comb, still use whatever comb you have. Doing something is always better than doing nothing. Even a regular plastic comb with teeth close together can remove adult bugs from wet, conditioned hair. It won't remove the eggs, but if you can get the bugs out before they lay more eggs, you are still ahead in the game and can still outrun the lice cycle over time.)
3. Hop in the bath or shower. Wet your head and saturate your head with hair conditioner. It doesn't have to be expensive conditioner. Any generic conditioner will do. Leave the conditioner in.
4. Use a brush to completely detangle your conditioned hair. Still leave the conditioner in.
And here's one other tool in the fight that you can use if you want...
7. Later on, grab your hair dryer. Separate your DRY hair into at least 20 sections (or grab one small section at a time.) Turn your blow dryer on the fastest setting - fastest but not hottest. Keep it on the warm (not hot) setting. Directing the hair to the scalp, blow dry each section for at least 30 seconds on one side and then 30 seconds on the other. In a study from the University of Utah, this directed blowing with a regular blow dryer was found to kill 53% of the bugs and 98% of the eggs. Though these numbers seem impressive, I find combing to be the most effective tool. If you have to choose between wet combing or blow drying, I'd go with combing. It actually gets things off the head.
No. Don't waste your money.
Don't I have to do a bunch of house cleaning and laundry now?
No. Don't waste your time.
And don't panic. You really can deal with this. It's not a disease. You didn't do anything wrong. It can happen to anybody. It's just head lice.
