Fact #1: Some lice may resist treatment.

While chemical based head louse treatment products used to be thoroughly effective, most recent studies show that some lice have grown resistant to some products already. This is why lice don't all die even when you follow product instructions. This is also the reason why you shouldn't immediately get angry or complain that you have been misled by a head louse treatment product. Some manufacturers simply cannot control how lice develop chemical resistance.

Fact #2: Resistance can develop from improper use of products.

This resistance to louse products are sometimes our fault. Lice sometimes develop resistance against typical head louse treatment products through the fault of some consumers. Studies again suggest that the improper application of some head louse treatment products may result in promoting resistance among lice.

Fact #3: Some products are only effective if meticulously used.

Avoid product resistance by following product instructions properly. You should strictly follow instructions as to the amount, frequency and duration of application. This is also the only way you can fairly assess if a specific head louse treatment product works or not. In some cases, you may not have a completely effective product even if you follow instructions strictly. This is if your child has acquired lice that are already treatment resistant.

Fact #4: They'll keep coming back if you don't clean up.

Away from host, lice can survive a day or two. This means that even if you have an effective head louse treatment, the lice on bed sheets, clothing, and other things around the house could get right back into your child's hair. You may have to thoroughly clean your kid's things and your house to completely get rid of lice. One tip is that lice hate heat so you may have to use your dryer and vacuum to help you.

Fact #5: Regular inspection is needed.

Children can easily get head louse from other children, too. You should therefore make regular head and hair inspections a home policy. Finding lice at an early time can help prevent severe infestations.

Fact #6: Hygiene education is still partly important.

Experts will tell you that excessive cleanliness cannot prevent lice infestations because lice like clean heads. You can however teach your kids hygiene practices and habits that matter. You can for example instruct them not to share combs, caps and clothing with their friends and classmates. Doing so could spread lice faster since some lice may transfer form one host to another through clothing or other personal possessions. Monitor both your child and his things.
