Why does HL7 Medicated Shampoo have to be applied to DRY hair?

  • Maldison vapourises when mixed with water and is breathed in by lice. This paralyses the central nervous system of head lice and nits. They don’t stand a chance of survival. It is important to apply the shampoo treatment to DRY hair as head lice shut their breathing holes once they get wet and can keep these shut for 30 minutes. 

If my child has lice must the whole family use HL7 Medicated Shampoo?

  • No – only use HL7 Medicated Shampoo when lice are visible

  • HL7 Shampoo should not be used on pregnant women or babies under 6 months old
  • HL7 Natural Treatment Lotion can be used instead as a natural preventative

Can I use HL7 Medicated Shampoo more often than every 7 days?

  • This is not recommended.
  • It is not necessary to use HL7 Medicated Shampoo more often as Maldison also has a residual effect that enables it to be present in the hair shaft in quantities still lethal to head lice for up to 7 days after treatment.
  • HL7 Medicated Shampoo may cause skin (scalp) irritation if over used 

Can I use HL7 Medicated Shampoo if I’m pregnant?

  • This is not recommended.
  • We recommend using HL7 Natural Treatment Lotion and the HL7 Lice Comb to remove lice and nits and to help prevent a re-infestation.

What are head lice and nits?

The head louse is a small wingless blood sucking insect 1.5 - 3 mm long and is a brownish-white colour in appearance. It lives and breeds on the human head. It does not live on any other host.

The adult louse may lay up to 130 eggs (nits) during a life cycle of around 34 days. The eggs are oval and yellowish-white and about 0.8 mm in size (approx. size of a sesame seed). They are firmly attached to the hair shaft at the base near the scalp by a cement-like substance. The eggs hatch in about 7-10 days. They can reproduce about 2 weeks after hatching.

What is the Head Lice Life Cycle?


Are head lice contagious?

Yes they are highly contagious. Getting head lice is not a social stigma. It is not a sign of uncleanliness or poor health habits, but it can be very upsetting and is definitely a nuisance. Head lice can occur at any age and to male or female at any time. Anyone who has close contact with an infested person is likely to be affected.

How are head lice acquired?

Head lice do not hop or fly they spread by close body contact or by using items such as hairbrushes, combs, ribbons, scarves and hats which have been in contact with an infested person. Lice can live approximately 2 days away from the host’s head.

How do I identify lice?

An infestation of head lice is often suspected when a person complains of irritation of the scalp and has an urge to scratch their head. It is confirmed by the presence of yellowish-white eggs found attached to the hair shaft as specks, as these are usually noticed first. The eggs have a gritty feel when feeling through the hair. Also look for discarded louse skins and black sandy particles on pillows and collars.

The lice, which are brownish-white in colour, are found in the hair close to the scalp. They are very difficult to see with the naked eye but you can identify them and their eggs more easily with the aid of a magnifying glass under a strong light.

To check, part the hair and look at the scalp at the nape of the neck, around the ears, the crown and fringes. Live lice will move away quickly when the hair is parted but the eggs will be more visible. Lice numbers may be reduced by grooming and scratching by their host.

Sometimes small white specks in the hair such as dandruff can be confused with eggs. Try removing the specks from the hair shaft. Dandruff will come off easily, but eggs are very difficult to remove.

It is important to remember that eggs are found close to the scalp. Any eggs found further along the hair shaft are either hatched or dead.

How Do I Prevent My Child From Getting Head Lice?

  • If you have a head lice infestation in your school or area you should thoroughly examine each child. If the child is found to have an infestation of head lice you should treat using HL7 Medicated Shampoo or HL7 Natural Treatment Lotion. 
  • If one member of the family has head lice, all members should then be checked and treated promptly.
  • The active ingredient in HL7 Medicated Shampoo can bind with the protein cystine in the hair, creating a residual effect helping to prevent re-infestation for up to 5-7 days after each treatment.
  • Alternatively during an outbreak, if no lice are yet present, use HL7 Natural Treatment Lotion every second day. HL7 Natural Treatment Lotion contains 12 essential oils, which linger in the hair to create a discouraging environment to lice. 

How Do I Stop Head Lice From Spreading?

  1. Treat all people that have come in contact with the infested person.
  2. Don’t share brushes, combs, scrunchies, hats, swimming caps, hooded clothes, ribbons, etc.
  3. Keep long hair tied back in pigtails, ponytails, plaits or buns.
  4. Check head and hair at least once a week.
  5. Contact your school or preschool staff nurse and all friends etc. and let them know as soon as possible.
  6. Wash all hairbrushes and combs in very hot water, 60˚C plus for 1 minute, taking precautions not to burn yourself.
  7. Suspect items that can’t be washed (eg. teddy bears, hats, bike helmets, etc.) can be isolated in a sealed plastic bag for 8-10 days.
  8. Lice do not survive well or for long off the human head, as they need to feed five or six times a day, therefore it may be a waste of time to wash all bed linen and spring clean the house.
  9. If very persistent infestations continue make sure other children, your child comes in contact with, are being treated. It may also then help to wash clothing, linen, towels, pillowcases and sheets in hot soapy water and preferably dry them in a hot dryer or leave in the hot sun
