Prescription drug, Ulesfia lotion is a trademark of Shionogi Inc. It is available in 8 oz bottle and eliminates the lice by suffocation. Although Ulesfia doesn’t kill the eggs, it is safe for use in children from six months and older.

Possible side effects: skin, scalp and eye irritation.

Direction for use: Apply an adequate amount of Ulesfia lotion to dry hair to completely saturate the scalp and hair; leave on for 10 minutes, and then thoroughly rinse off with water. Repeat treatment after 7 days.

The bottom line

While Cetaphil Cleansing lotion and Ivermectin Stromectol have been proven efficient, these are not FDA approved. More to this, Stromectol has a higher risk for untoward reactions since it is taken orally. United Home Sulfur has the least convenience for use because of its ointment form. While shampoos are the best choice for head lice treatment, lotions are also preferred for relief as they give better skin coverage than creams or ointments.

Citronella maybe from a natural source but it can only repel head lice. In addition, citronella is not advised for children under 3 years old. Kwell and Licealiz have no contraindication in children and in pregnant women. However, Kwell and Licealiz have been documented for lice resistance.

Finally, Ulesfia is probably the most recommendable among the seven optional head lice treatments. It is approved by the FDA for head lice. It is not contraindicated in pregnant women and in infants from 6 months. And since, Ulesfia is not an insecticide like Kwell or Licealiz, it won’t develop lice resistance.
