Lyclear Express Spray 100ml

 

What Is Lyclear Express Head Lice Spray?

 

Head lice are a common problem in the UK, particularly among school-age children. In fact, the NHS estimates that they affect millions of children every year, spreading easily through direct head-to-head contact. If you've spotted the telltale signs — an itchy scalp, tiny white eggs attached to hair shafts, or live lice moving through the hair — you'll want something that works quickly and reliably. That's exactly where a head lice spray like Lyclear Express Spray 100ml comes in. Available from our head lice treatment collection, this product offers a straightforward, insecticide-free approach to clearing an infestation.

Lyclear Express Spray contains dimeticone 4% as its active ingredient. Dimeticone is a silicone-based compound that works physically rather than chemically, which means it doesn't rely on toxic insecticides to do its job. This is particularly reassuring for parents who are cautious about what they apply to their child's scalp.

 

How Does Lyclear Express Spray Work?

 

Unlike older lice treatments that used insecticides such as permethrin or malathion, Lyclear Express Spray takes a purely physical approach. The dimeticone coats the lice and their eggs in a thin silicone film, blocking their ability to manage water and ultimately causing them to die. Because it doesn't interfere with the nervous system of lice, there is no risk of resistance developing over time — a real advantage given that insecticide-resistant lice have become increasingly common in the UK.

• Dimeticone 4% coats the outer surface of lice and eggs
• Blocks the lice's ability to excrete water, leading to death by osmotic stress
• Eggs are also coated, preventing hatching
• No insecticide means no risk of chemical resistance
• Works in as little as 15 minutes of contact time

 

Who Should Use Lyclear Express Spray?

 

This product is suitable for most people who have an active head lice infestation. It's particularly well suited to families with school-age children, where re-infestation is common and repeated treatments may be needed throughout the year. It can also be used by adults who have caught lice through close contact.

• Children aged 6 months and over (with adult supervision)
• Adults with an active head lice infestation
• Those who have experienced treatment failure with insecticide-based products
• Individuals who prefer a chemical-free, insecticide-free approach

It is not recommended for babies under 6 months without medical advice. If you are pregnant, breastfeeding, or have a known skin condition affecting the scalp, speak to your pharmacist before use.

Is Lyclear Express Spray Suitable for Sensitive Scalps?

 

Dimeticone is generally well tolerated, even on sensitive skin. Because it is not absorbed into the bloodstream and works entirely on the surface of the hair and scalp, systemic side effects are not expected. That said, if you or your child has a known allergy to any of the ingredients, you should check the full ingredient list before use. You can also browse our hair care range for complementary products to use alongside treatment.

Store the spray below 25°C, away from direct sunlight and out of reach of children. Keep away from open flames — the formulation is flammable.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Lyclear Express Spray and What Is It Used For?

 

Lyclear Express Spray 100ml is an over-the-counter topical treatment used to kill head lice and their eggs (nits) in human hair. It contains dimeticone 4%, a silicone-based ingredient that physically smothers lice rather than using chemical insecticides. It is used to treat active head lice infestations in adults and children aged 6 months and over. The NHS recommends wet combing or a suitable lotion or spray as the two main approaches to treating head lice, and dimeticone-based products are among those recommended.

Head lice cannot jump or fly — they spread only through prolonged, direct head-to-head contact. They do not indicate poor hygiene. Anyone can get them, and treating the whole household at the same time is often advised to prevent re-infestation.

 

What Do You Need to Know Before Using Lyclear Express Spray?

 

Before using this product, read the following carefully. Do not use Lyclear Express Spray if any of the following apply to you:

• You are allergic to dimeticone or any other ingredient in the formulation
• The person being treated is under 6 months of age
• You have open wounds, cuts, or broken skin on the scalp
• The person has severe eczema or psoriasis affecting the scalp (seek medical advice first)

Take extra care in the following situations:

• Pregnancy or breastfeeding — speak to your pharmacist before use
• Asthma — avoid inhaling the spray during application
• Use near open flames or heat sources — the product is flammable
• Application near the eyes — avoid contact; rinse immediately with water if contact occurs

Drug interactions: No significant drug interactions are known for topically applied dimeticone. However, always inform your pharmacist of any other medicines you are using.

• No known interactions with oral medications
• Avoid using alongside other scalp treatments at the same time without pharmacist advice

 

How Should You Use Lyclear Express Spray?

 

Always follow the instructions in the patient information leaflet supplied with the product. The general method of use is as follows:

1. Ensure hair is dry before application
2. Shake the bottle well before use
3. Apply the spray evenly across the entire scalp and all hair, from roots to tips
4. Pay particular attention to the areas behind the ears and at the nape of the neck, where lice tend to congregate
5. Leave the product on the hair for a minimum of 15 minutes
6. Using a fine-tooth nit comb, comb through the hair section by section to remove dead lice and eggs
7. Rinse the hair thoroughly with shampoo and warm water
8. Repeat the full treatment after 7 days to kill any lice that may have hatched from eggs since the first application

If you are treating a child, ensure they keep their eyes closed during application and avoid the spray coming into contact with their face. You may also find it helpful to browse our baby and toddler range for other products suitable for younger children.

 

What Are the Possible Side Effects of Lyclear Express Spray?

 

Like all medicines, Lyclear Express Spray can cause side effects, although not everyone will experience them. Because dimeticone is not absorbed through the skin, systemic side effects are not expected. Most reactions, if they occur at all, are localised to the scalp or skin.

Common side effects (may affect up to 1 in 10 people):

• Mild scalp irritation or itching after application
• Temporary skin redness at the application site
• A slight greasy or heavy feeling in the hair immediately after use

Less common side effects (may affect up to 1 in 100 people):

• Stinging or burning sensation on the scalp
• Dry or flaky scalp following repeated use
• Allergic skin reaction (rash, hives) — stop use immediately if this occurs

If you experience any signs of a serious allergic reaction — including swelling of the face, lips, or throat, or difficulty breathing — seek emergency medical attention immediately. This is rare but requires urgent care.

 

How Should You Store Lyclear Express Spray?

 

Correct storage helps maintain the product's effectiveness and keeps it safe for use. Follow these storage guidelines:

• Keep away from direct sunlight and sources of heat
• Do not store near open flames — the product is flammable
