How to treat head lice
The aim is to kill the head lice and the eggs.
Option 1 : Continue with the conditioner and comb method every second day until there’s no sign of live lice for 10 days. Eggs hatch so be sure to repeat.
Option 2 : If you choose an insecticide product, make sure it has been approved by the Therapeutic Goods Administration for use. (AUST R or AUST L number on the packaging)
Do not use an insecticide product:
- If you are pregnant/breast feeding
- In children less than 12 months old
- If you have allergies, open wounds, or asthma
When using an insecticide:
- If it’s a lotion product the hair should be dry
- If it’s a shampoo, then the hair should be wet
- It’s important to follow the product instructions
- After treatment, use the head lice comb to remove dead eggs and head lice
- This will also help to see if the treatment has been successful
- No insecticide kills 100% of the eggs the first-time round so repeat the process 7 days later
- If the head lice are still alive it’s possible they are resistant to that particular insecticide
- Revert to the combing method or talk to your pharmacist or doctor to try another product
