About The HairClean Lice Comb The comb included in each package of HairClean was designed based on feedback from health professionals around the country. The HairClean 1-2-3 comb has long, sturdy, stainless steel teeth that pull the nits (eggs) from the hair. The HairClean tines are closely spaced to eliminate the nits, but each tooth is rounded and slightly angled at the tip to keep the comb from tearing or damaging the hair or scalp. The large handle makes the HairClean comb easy to use.

Schools/Nurses/Health Agencies HairClean is used by many schools, public health departments, head start programs, rural health agencies and other non-profit health groups throughout the United States. Health Professionals prefer HairClean 1-2-3 because it is effective, safe, and easy to use. It works in 15 minutes, leaves the hair shiny and easy to nit-pick. Even lice that have developed immunity to many treatments are not resistant to HairClean. According to Quantum's survey of over 1,000 school nurses 75% say head lice have increased over the last three years. On average, 10% of the elementary school student body gets head lice. Each student is absent an average of 4.2 days. These statistics are alarming. Head lice result in lost education days, lost funding due to non-excused sick days, and lost income to parents who must stay home to care for their lice-ridden children. The solution is better education and more effective products. We provide both.
