Mostly those cause itching and ulceration in scalp. Sometimes painful lymph nodes appear in the head and neck secondary to infected scalp.
Once detected it should be treated to get rid of lice. Before going for specific treatment by medicated lotions or shampoo, it is better to follow some household methods;
· Wet combing of hair by fine toothed comb. It is likely to be repeated s few times to completely get rid of lice.
Medicated lotons/shampoo include;
· Permethrin cream 1%, to be reapplied after one week.
· Pyrethrin 0.33% and piperonyl butoxide 4% may be repeated after one week,.
· Malathion 0.5% lotion
· Lindane 1% shampoo not repeated if initial treatment fails.
By far permethrin is very good and safer than other chemicals, but not safe in infants below 2 months of age.
· The cream need to be applied for 10 minutes before rinsed off.
· It should be repeated after one week to ensure cure.
Additional measures include;
- Family members need to be treated only if infected
- Personal hair care items should be treated with pediculocides or soaked in hot water.
- Bedding should be washed in hot water of at least 50 degrees.
- Wet hair should be towel dried before using treatment as too much water in the hair dilutes the pediculicide, decreasing its efficacy.
- Conditioner shampoo should not be used before using the treatment as it may interfere with the medication.
- Hair is not to be washed for 1 to 2 days after treatment.
- Schools or child care facilities should be notified so that additional cases can be detected and treated.
