Scalp Hair Removal Cream for Mens
The contents of the tube were applied to dry hair and the scalp, left on for 10 minutes, then rinsed off with water. No one was supposed to use a comb to remove nits (juvenile lice) attached to hair strands. A clinician checked the person’s head two days later, then again one and two weeks later. (Two weeks post-treatment is a good benchmark, because it takes about that much time for a louse egg to hatch and the nymph to become an adult.)
On day two, 95% of those who used the ivermectin lotion were louse free, compared to 31% of those who used the placebo lotion. On day 15, the score was ivermectin 74%, placebo 18%.
Some people in the study experienced side effects, which include eye irritation, a burning sensation in the skin, and skin redness. These were slightly less common among those using ivermectin.
Good back-up player
Although these results look spectacular, here are a few things to keep in mind:
The trials compared ivermectin with a placebo, not another remedy for head lice known to be effective way of treating head lice and nits. It makes sense that any treatment with an active ingredient would do better than a lotion with no medication at all.
Treatment of head lice traditionally calls for the use of an over-the-counter product containing permethrin or pyrethrins as a first salvo against head lice. Shampoos and rinses made with these substances generally work well. Most treatments for head lice need to be used twice, seven to 10 days apart, along with combing wet hair with a fine-toothed comb to remove nits. Some lice are resistant to pyrethrins and permethrin. That’s when it makes sense to turn to stronger prescription drugs, such as ivermectin and spinosad (Natroba).
Don’t overlook the value of nit combing. “Combing works, ” says Dr. Claire McCarthy, a pediatrician at Harvard-affiliated Boston Children’s Hospital. “It takes patience and perseverance, but not only does it get rid of both live lice and eggs, it’s completely nontoxic and without side effects. That can’t be said of any other treatment for head lice, ivermectin included.” She also recommends checking everyone’s head in the family, adults included, and laundering in hot water sheets, pillowcases, clothing, and anything else that may have come in contact with the heads of those affected. Temperatures above 122 °F kill adult and juvenile lice.
