Every business has an origin story, but ours started with something a lot more relatable than a boardroom idea: a scratching scalp, a stack of pharmacy products that didn't work, and a fair amount of desperation.

A New York bathroom, a bottle of Listerine, and nothing that worked

Our founder, Deb, was living overseas in New York when her children first came home with head lice and, as often happens, she caught them too. She describes it as disgusting and overwhelming, and in the scramble to fix it, she tried everything the chemist had to offer, and then some. Olive oil. A full bottle of Listerine poured over the kids' heads. None of it worked.

Eventually, Deb found a woman who removed head lice using nothing more than a comb and a conditioner a method that, in her words, "just made sense." It turned out the trick was never about the products at all. It was about the technique. As she later told the Sydney Morning Herald, "Nobody teaches how to comb anymore."

Bringing the method home to Sydney

When the family moved back to Sydney in 2011, Deb set up a mobile head lice service built entirely around that comb-and-conditioner method visiting families in their own homes rather than asking them to come to a clinic. It's the same technique every No Nits specialist is still trained in today.

The science behind why combing works better than chemicals

This isn't just a personal preference - it's backed by genuine research. Cameron Webb, a lecturer at the University of Sydney, has studied a phenomenon called "knockdown resistance" - a genetic mutation in head lice that makes them significantly less vulnerable to common insecticide treatments. In practical terms, this means many of the chemical treatments sold at pharmacies simply don't kill lice as effectively as they once did, because the lice themselves have evolved to resist them.

Webb's own recommendation lines up exactly with the method we use: a thorough comb-and-conditioner treatment, repeated again about a week later to catch anything that hatches in between. That second treatment isn't an optional extra, it's the part of the process that actually breaks the cycle, which is exactly why we recommend a follow-up comb 5–7 days after every treatment we do.

Empowering families to handle it themselves

One thing that's stayed consistent since day one is a genuine focus on teaching, not just treating. Deb has always seen part of the job as showing parents how to manage head lice themselves - not creating ongoing dependence on a service. That same philosophy is still baked into how we operate today: we're always happy to walk you through the follow-up comb yourself, and we sell a proper nit comb for exactly this reason, so you've got the right tool to finish the job without needing to book us again.

Frequently asked questions

Is it true that chemical head lice treatments don't work as well as they used to?
Research on "knockdown resistance" shows many head lice populations have developed genetic resistance to common insecticide treatments, reducing their effectiveness.

What is knockdown resistance?
It's a genetic mutation in head lice that makes them less susceptible to certain insecticide-based treatments — meaning some chemical products are less reliable than they were decades ago.

Why does No Nits use a comb and conditioner method instead of chemical treatments?
Because it physically removes lice and eggs rather than relying on chemistry — which means it isn't affected by resistance the way some chemical treatments are.

Do I need a follow-up treatment even if the first comb went well?
Yes - a follow-up 5–7 days later is a core part of the process, not an optional extra, and it's supported by the same research referenced above.
