What Is Hedrin 4% Lotion?

Hedrin 4% Lotion is a clinically proven treatment for head lice and their eggs. It contains dimeticone, a silicone-based ingredient that physically coats and suffocates lice, rather than using traditional pesticides. This makes it a great option for children and adults, even for those with sensitive skin or asthma.

Unlike some treatments that use harsh chemicals, Hedrin 4% Lotion is gentle, odourless, and easy to use. It is suitable for adults and children aged 6 months and over.

How Does Hedrin 4% Lotion Work?

Hedrin works by coating head lice in a physical layer of dimeticone, which blocks their ability to regulate water and oxygen. This causes the lice to die without needing toxic insecticides. Since it doesn't rely on chemical poisons, there's no risk of lice developing resistance.

How to Use Hedrin 4% Lotion

Follow these steps for best results:

  • Apply the lotion evenly over dry hair, covering the scalp and all strands.
  • Work the lotion into the hair using your fingers or a comb.
  • Leave the product on the hair for at least 8 hours or overnight.
  • Wash out thoroughly with shampoo (do not use conditioner first).
  • Repeat treatment after 7 days to kill any newly hatched lice.

Always read the instructions provided in the packaging before use.

How Many Bottles of Hedrin 4% Lotion Will I Need?

The number of bottles you'll need depends on the length and thickness of the hair being treated. As a general guide:

  • Short hair: One 50ml bottle is usually enough for one full treatment.
  • Shoulder-length hair: You may need up to 100ml per application.
  • Long or thick hair: You may require more than 100ml, or multiple bottles, to ensure full coverage.

Remember, a second treatment is needed after 7 days, so you may want to purchase enough for two full applications per person. It's always better to have a little extra to make sure every part of the scalp and hair is fully treated.

Who Can Use Hedrin Lotion?

Hedrin 4% Lotion is suitable for adults and children aged 6 months and over. It is safe to use in people with asthma and those with sensitive skin. It can also be used during pregnancy and breastfeeding.

Side Effects & Precautions

Hedrin is generally very well tolerated. Side effects are rare but may include:

  • Itching or irritation of the scalp
  • Flaking or dryness (mild and temporary)

If you notice any severe irritation or allergic reaction, stop using the product and speak to a healthcare professional.
