Pediculosis Capitis

What Is Pediculosis Capitis?

Pediculosis Capitis, commonly known as head lice, is a common parasitic infestation of the scalp caused by Pediculus humanus capitis. It mainly affects school-aged children but can occur in people of any age. Head lice are not a sign of poor hygiene and are spread through close head-to-head contact.

How Does It Spread?

* Direct head-to-head contact
* Sharing combs or hairbrushes
* Sharing hats, scarves, helmets, or hair accessories
* Sharing pillows or bedding (less common)

Common Symptoms

* Intense itching of the scalp
* Tickling or crawling sensation in the hair
* Small red bumps on the scalp or neck
* Scratch marks or sores due to itching
* Visible lice or tiny eggs (nits) attached firmly to hair shafts, especially behind the ears and at the back of the neck

Commonly Affected Areas

* Scalp
* Behind the ears
* Back of the neck

Diagnosis

Diagnosis is based on:

* Medical history
* Physical examination
* Identification of live lice or nits on the scalp and hair

When Should You See a Dermatologist?

Consult a dermatologist if:

* Persistent scalp itching continues despite treatment.
* Live lice continue to be seen after treatment.
* The scalp becomes infected due to scratching.
* The diagnosis is uncertain or another scalp condition is suspected.
* Infestation keeps recurring.

Prevention

* Avoid head-to-head contact during outbreaks.
* Do not share personal hair care items.
* Regularly inspect children’s hair if there is an outbreak at school or home.
* Wash clothing, hats, pillowcases, and bedding used by an affected person.
* Clean combs and hairbrushes thoroughly.

Important Facts

* Head lice are not caused by poor hygiene.
* They do not spread disease.
* Anyone can get head lice regardless of age, gender, or hair type.
* Early detection helps prevent spread to family members and close contacts.
