Head Lice: When to Call a Professional?

Most people with head lice don't need to consult a doctor as over-the-counter medications containing one of the active ingredients pyrethrins (natural extracts from the chrysanthemum flower) or permethrin are effective for curing the infestation. Find out when to call a doctor for head lice.

You may want to consult a doctor for head lice:

• If you want to confirm if you or your child is infected with head lice.
• Once over-the-counter products for lice treatments have not worked.

When you go to consult your doctor:

• Write a detailed description of your symptoms.
• Note your past medical problems.
• Note the problems you want to ask the doctor.

The doctor will examine your hair and scalp for lice and nits. If there is doubt a special light, called a Wood's light, may be used as it makes the nits look pale blue.
