They are the bane of many parents’ lives.<\/p>\n
Not only do headlice cause incessant itching, but treating them is an ordeal in itself, with tears, tantrums and products often potent enough to knock you out.<\/p>\n
And as the schools go back – and we hit peak nit season \u2013 hundreds of thousands of youngsters will be affected.<\/p>\n
Why? Because the small insects are highly adapted to one type of environment: hair on a human’s head – especially primary school-aged children.<\/p>\n
Infuriatingly, in the battle of human’s vs headlice, it’s the parasite that’s winning.<\/p>\n
Scientists have warned that lice are becoming increasingly resistant to products \u2013 leaving parents with fewer options than ever.<\/p>\n

The small insects are highly adapted to hair on school-aged children’s heads, experts warn<\/p>\n
And last year, it was reported that a strain of ‘super lice’ was now affecting half of the states in the US.<\/p>\n
These so-called ‘super lice’ are resistant to 98 per cent of over-the-counter remedies’ \u2013 containing pyrethrins and permethrins – the active ingredients in most popular treatments.<\/p>\n
This is because they carry genetic mutations which make them immune to the pesticide.<\/p>\n
In the UK, this resistance figure is 87 per cent, according to research published in the Journal of Medical Entomology.<\/p>\n Yet two-thirds of parents with school-age children have dealt with an infestation, a poll by Puressentiel, a company that makes clinically proven essential oil products, found.<\/p>\n On average, families face three or four encounters with the itch-inducing insects while their children are at school, one in 10 parents has been forced to deal with 10 or more infestations.<\/p>\n And while lice are becoming resistant to many popular treatments, a big part of the problem is parents not letting on their children have nits \u2013 enabling them to spread to other members of their child’s class, says Dr Gill Jenkins, a GP in Bristol.<\/p>\n ‘Usually it’s because they are embarrassed, but there are some parents who unfortunately don’t \u2013 or can’t \u2013 deal with lice effectively, causing other kids to become infested,’ she explains.<\/p>\n Getting the the root of the problem<\/span><\/p>\n In recent years, the appetite for chemical treatments has plummeted \u2013 not only because they are because they are becoming less effective, but because parents are reluctant to smother their children’s scalps in such potent substances \u2013 sometimes for several hours at a time.<\/p>\n In fact, the NHS has advised against the use of pesticide-based chemical treatments for some time, explains Dr Chris Etheridge, a practicing medical herbalist and plant medicine expert.<\/p>\n Earlier this year, French academics warned chemicals in head lice treatments could lead to behavioural problems in young children.<\/p>\n Pregnant women exposed to pyrethroids – a group of synthetic chemicals used in common pesticides – were more likely to have children who develop social behaviour problems by the age of six, their study found.<\/p>\n The chemicals were developed by British scientists in 1960s as a safe alternative to organophosphates \u2013 the basis of many insecticides, herbicides, and nerve agents.<\/p>\n And as the schools go back – and we hit peak nit season \u2013 hundreds of thousands of youngsters will be affected, they say<\/p>\n But the researchers, from the University of Rennes, suggested pyrethroids may not be as safe as previously thought.<\/p>\n They suspect the chemicals might alter neurochemical signalling in the brain, altering a child’s development.<\/p>\n Now, there is a second generation of treatments which use a physical action to kill lice \u2013 and these are recommended by the NHS, explains Dr Etheridge.<\/p>\n ‘Some coat lice in a greasy film of dimeticone, a type of silicone which works by coating the lice, stopping them from getting the supply of water they need to stay alive,’ he explains.<\/p>\n Head lice are small grey-brown insects that live only on human scalps. They cannot fly or jump; neither can they burrow into the scalp. They can affect anyone, with long or short hair, no matter how clean the hair is.<\/p>\n They are usually contracted by head-to-head contact; it takes about 30 seconds for a single louse to transfer from one scalp to another.<\/p>\n Head lice can affect anyone, but are:<\/p>\n Most common in children between the ages of 4 and 11, particularly girls, and are most common at the start of the school year<\/p>\n Female lice live for up to 40 days, during which time they can lay more than 100 eggs. They attach their eggs (known as nits) to hairs close to the scalp surface.<\/p>\n Lice make the head itch because their bites cause an allergic reaction.<\/p>\n An affected scalp carries a mixture of the following:<\/p>\n \u2022 Eggs containing developing lice \u2013 firmly stuck to the hair shafts near to the scalp<\/p>\n \u2022 Empty egg cases \u2013 also firmly stuck to the hairs, but further from the scalp surface<\/p>\n \u2022 Immature lice<\/p>\n \u2022 An average of 10 adult lice, though some scalps carry many more<\/p>\n \u2022 Louse droppings \u2013 most easily seen as dark specks on pillows or clothing<\/p>\n Source: British Association of Dermatologists<\/p>\n The problem, he says, is that dimeticone treatments must be left in the hair for eight hours.<\/p>\n And with their pungent smell and oily consistency, they are widely loathed by parents and children alike.<\/p>\n ‘As a parent myself, I used to worry about putting such strong chemicals on my children’s heads \u2013 especially for periods of several hours,’ says Dr Jenkins.<\/p>\n ‘Some of the chemicals are so strong that their fumes can cause breathing difficulties, especially in people suffering with conditions such as asthma.<\/p>\n ‘Such products are also clearly not advisable for people with sensitive skin or eczema.’<\/p>\n Not only that, the preparations can be so greasy that they carry warnings about slipping and it can be difficult to rinse them out with normal shampoo.<\/p>\n Indeed, ‘anecdotal reports of washing-up liquid being required to remove it are common,’ a report published in the journal Prescriber warned.<\/p>\n A new way to fight nits<\/span><\/p>\n Research is increasingly showing that essential oils have potent pesticidal properties \u2013 and are a natural, chemical free weapon in the war on headlice.<\/p>\n ‘Although they are often lumped together, there is a huge range of different herbal treatments on the market,’ explains Dr Etheridge.<\/p>\n ‘Most use one or more essential oils, but their effectiveness \u2014 or lack of efficacy \u2014 is dependent on the combination, concentration and quality of the oils used.<\/p>\n ‘There is compelling evidence that tea tree, lavender and eucalyptus all have some anti-lice activity, and plant oils which block the louse’s respiratory system, in much the same way as dimeticone, have also been shown to be effective.<\/p>\n ‘But it is very much buyer beware. Just because a product contains some of these ingredients, it does not guarantee it will work.<\/p>\n ‘And whatever product is used, it’s important to comb the hair thoroughly with a fine-toothed comb afterwards, to remove dead lice and dislodge any which might have avoided coming into contact with the treatment, or have had minimal exposure.’<\/p>\n A study published in the journal Parasitology Research reported a 100 per cent kill rate using a 1 per cent solution of tea tree oil.<\/p>\n And an Australian study published in BMC Dermatology found a combination of tea tree and lavender oils was as effective as a ‘suffocation’ product, with both delivering 97.6 per cent clearance, compared to just 33.3 per cent from a pyrethrin based treatment.<\/p>\n Researchers commented that the tea tree and lavender oil combination ‘exceeded the efficacy of another essential oil product’.<\/p>\n Meanwhile an evidence review, reported in BMJ Best Practice, found: ‘Herbal and essential oil treatment containing eucalyptol [the active agent in eucalyptus oil] may be more effective at eradicating lice compared with [a traditionally used chemical called] malathion.’<\/p>\n \n Mother-of-three Rebecca, from Hertfordshire, has three boys aged 3, 6 and 9. She believes a cure for nits may already exist in the form of a \u00a312.99 lotion and comb pack available on the high street.<\/p>\n She said: ‘I have always dreaded my boys getting nits and until recently, we managed to avoid them.<\/p>\n ‘I don’t like putting chemicals on my kid’s heads or skin at all. I also hate the smell and fumes – they affect my breathing \u2013 and I’ve heard from other mums that many don’t seem to work.<\/p>\n ‘There’s so much conflicting advice \u2013 but after researching many options online, I decided to buy an essential oil-based product, rather than a chemical based one.<\/p>\n ‘The Puressentiel Anti-Lice Treatment Lotion pack was clear and it claimed the product was proven to eliminate lice, larvae and nits in just 10 minutes. Apparently, it does this thanks to the vegetable and essential oils in it \u2013 they suffocate the lice.<\/p>\n ‘The leaflet explained the lotion also contains plant oils like jojoba, sunflower, sweet almond and coconut. These oils help repel the lice whereas the lavender, tea tree, clove destroy lice, larvae and nits.<\/p>\n ‘The lavender, tea tree and geranium cleanse and soothe the itching.<\/p>\n ‘I have many of these plants in my garden \u2013 but had no idea they had such uses.<\/p>\n ‘The rest of us used the repellent spray to try and avoid getting them.<\/p>\n ‘I applied the anti-lice lotion onto my son Tom’s dry hair and scalp, covering all roots and hair ends.<\/p>\n ‘After 10 minutes, I simply washed it off like a normal shampoo and rinsed through.<\/p>\n ‘Then came the fun part \u2013 combing out the bugs. The comb produced lots of nits, larvae and dead lice \u2013 something Tom thought was fascinating.’<\/p>\n ‘Thankfully, the lice haven’t come back.’\u00a0<\/p>\n \n","protected":false},"excerpt":{"rendered":" They are the bane of many parents’ lives.
