Lice

Lice are a type of insect that thrives on human blood and are usually found on the scalp or pubic area. Adult lice are whitish in colour and about the size and shape of a sesame seed. Lice eggs (also known as nits) appear similar to dandruff and are often found attached to individual hairs, usually where the strand of hair meets the scalp.  

Lice frequently affects school-age children, as the insects can spread easily from person to person. While infestations are upsetting, there are lots of effective ways to eliminate lice.  

How Lice Are Spread 

Lice can inhabit the hair on the scalp, as well as the hair in the pubic region. There are also body lice, which appear in numerous areas.  

Because lice lack wings, they must be spread through direct contact with the insects themselves or their eggs. Body to body contact is a common transmission method, but you can also acquire lice by handling infested belongings.

Symptoms 

People with lice often experience: 

  • Itching and tickling sensations on the scalp and elsewhere on the body 
  • Bite marks around the area of infestation 
  • Small, red bumps that appear due to incessant scratching 

It is also common to see signs of lice during an infestation. You may see the insects on the scalp or body or see their eggs attached to hair shafts.  

Treatment 

Non-prescription medicated shampoo can treat all types of lice. Doctors can also prescribe an oral or topical medication if non-prescription treatments are ineffective.  

People with lice must also take steps to eliminate the insects and eggs from their homes. This involves laundering bedding using detergent and hot water, checking other people in the home for lice, and thoroughly vacuuming any carpeting. If there are items in your home that cannot be laundered, it is best to place them in an airtight bag or container for two weeks (as lice will die without access to sustenance).  

It is not always possible to prevent lice infestations, especially with kids in the home. However, you can provide tips to your kids to limit their exposure: 

  • Advise your child not to share brushes and combs with others 
  • Encourage them to be mindful of head-to-head contact with friends 
  • Do not let kids try on other children’s hats or hair accessories 

Prevention is key, not sharing brushes and combs, encouraging mindfulness about head-to-head contact, and avoiding the sharing of hats or hair accessories can go a long way in maintaining healthy hair habits.
