Lice need at least 1/4" of hair to hide, reproduce, and keep warm. Hair that has been coated with hairspray, gel, oil, or mousse is less hospitable to lice than clean hair. The louse cannot adhere as easily to the strands if they have a protective coating. Lice can easily survive on all textures, from very curly to completely straight. It does seem they have an easier time reproducing if there's a little bit of texture, like waves or loose curls. The answer to that is no; they will go to any head that has hair available.

Estimates suggest that each year, between 6 and 12 million infestations affect kids ages 3 to 11 in the United States. Head lice are not an indicator of a person’s cleanliness and occur across all socioeconomic groups. “I’ve even heard of salons shutting down entirely when they have a client with lice! Just wipe down your station with bleach, sanitize combs in Barbicide and wash capes according to state code regulations.
Prevention & Control
So if you see what looks like nits more than a centimetre or two away from the scalp it means the eggs have already hatched and you may be seeing a sign of a previous infestation. The only way you can catch head lice is by direct hair contact. That's why primary school students, especially those with long hair, are more likely to catch lice — they love crowding around smartphones, tablets or books together. Read on to learn more about head lice spread, how to treat infestations, and what you can do to avoid getting head lice.
How we vet brands and products
Head lice are spread most commonly by direct head-to-head (hair-to-hair) contact. However, much less frequently they are spread by sharing clothing or belongings onto which lice have crawled or nits attached to shed hairs may have fallen. The risk of getting infested by a louse that has fallen onto a carpet or furniture is very small. Head lice are spread by direct contact with the hair of an infested person. Anyone who comes in head-to-head contact with someone who already has head lice is at greatest risk. Spread by contact with clothing (such as hats, scarves, coats) or other personal items (such as combs, brushes, or towels) used by an infested person is uncommon.
Who might get head lice?
Data show that head lice can survive under water for several hours but are unlikely to be spread by the water in a swimming pool. Head lice have been seen to hold tightly to human hair and not let go when submerged under water. Head lice are spread most commonly by direct contact with the hair of an infested person.

How to get rid of head lice
However, it's not realistic to expect that you and your child can avoid all contact that may cause the spread of lice. Unless treated properly, lice can become a recurring problem. Lice are excellent "tightrope walkers" of the hair, but grease up that rope, and it's a lot harder to walk. Each of their little legs has claws specifically designed to cling onto each hair strand and not fall off. Just follow the step-by-step videos and be done with lice by the end of the day. Other home remedies include putting everything from lemon or orange juice to mayonnaise or yoghurt on the scalp.
Dandruff lies on the scalp and comes away easily, whereas nits stick to the hair. The itchiness is the result of a local allergic reaction to the lice bites. The eggs, or nits, are tiny ovals that stick to the hair shaft, measuring 0.8 mm by 0.3 mm. Head lice have six legs and are usually grayish-white or tan.
Q: Do head lice only like clean hair?
According to experts, it doesn’t make a difference if you recently washed your hair or not. Anyone can get lice if they come into close contact with someone who has them. However, some research suggests that certain groups may be more prone to head lice than others. You can buy a special fine-toothed comb (detection comb) online or from pharmacies to remove head lice and nits. Permanent hair dye and bleaching solutions also may contain hydrogen peroxide. Studies have found that this chemical effectively treats sea lice, but more research is necessary to determine its effects on head lice.
The National Association of School Nurses notes that classroom or schoolwide nit checks aren't effective at preventing incidences of lice in schools. A person can take steps to prevent head lice, such as avoiding sharing clothes, washing clothing and bedding that a person with lice has used, and not sharing personal care products. A person can purchase medications for head lice OTC at most pharmacies.
Spread by contact with inanimate objects and personal belongings may occur but is very uncommon. Head lice feet are specially adapted for holding onto human hair. Head lice would have difficulty attaching firmly to smooth or slippery surfaces like plastic, metal, polished synthetic leathers, and other similar materials. If you think you've rid yourself of head lice only to have them return a couple of weeks later, chances are you didn't get every last louse and nit. Following through with treatment, repeating combing, and re-shampooing (per directions) are critical.
Those affecting humans tend to be blood-sucking species that rely on blood and other secretions to survive. When school outbreaks occur, the infestation can easily spread to family members and others. However, lice infestations can also be asymptomatic, especially in early or mild infestations. Keep in mind that because anyone with hair can get lice, everyone in the family should be checked. LiceDoctors treats children and families with all hair types.
Personal hygiene or cleanliness in the home or school has nothing to do with getting head lice. Head lice and their eggs (nits) soon perish if separated from their human host. Adult head lice can live only a day or so off the human head without blood for feeding. Nymphs (young head lice) can live only for several hours without feeding on a human.
Thorough treatment of head lice is necessary to ensure all lice have been eliminated. This includes removing head lice from hair and any personal items that may have been infested. It's difficult to prevent the spread of head lice among children in child care facilities and schools because there is so much close contact. Nonprescription and prescription medications can help treat head lice.
In the United States, cases of head lice most often occur in children in preschool through elementary school. Head lice often spread from one person to another by direct head-to-head contact, often within a family or among children who have close contact at school or play. See a health care provider before you begin treatment if you suspect that you or your child has head lice.
