What Is Lyclear Creme Rinse — a Head Lice Treatment?
Head lice are a common problem, particularly in school-age children, and they spread easily through close head-to-head contact. If you've spotted the telltale signs — persistent itching, tiny eggs stuck to hair shafts, or live lice moving through the hair — you'll want something that actually works. Head lice treatment with Lyclear Creme Rinse Twin Pack 2 x 59ml gives you two full-sized bottles so you can complete the recommended two-application course without needing to reorder. You can browse our full range of products in our head lice collection if you'd like to compare options.
Each 59ml bottle contains permethrin 1% w/w as the active ingredient. Permethrin is a well-established synthetic pyrethroid that has been used in head lice management for decades. The twin pack format is particularly practical for families, since the NHS recommends repeating treatment after seven days to catch any lice that hatch from eggs surviving the first application.
How Does Lyclear Creme Rinse Work Against Lice?
Permethrin works at a neurological level. It targets the sodium channels in the nerve cell membranes of head lice, preventing them from closing properly. This causes prolonged nerve firing, leading to paralysis and death of the louse. It's a targeted mechanism — it doesn't rely on physically smothering lice the way some silicone-based products do.
- Permethrin binds to voltage-gated sodium channels in louse nerve cells
- Sodium channels remain open, causing continuous nerve stimulation
- The louse becomes paralysed and dies within hours of contact
- A second application after 7 days targets any newly hatched lice from surviving eggs
Who Should Use Lyclear Creme Rinse Twin Pack?
This product is suitable for most adults and children aged 6 months and over. It's particularly useful for households where more than one family member has been affected, since the twin pack provides enough product for two full treatment courses. That said, it isn't right for everyone.
- Adults and children aged 6 months and over with confirmed head lice
- Families needing to treat multiple household members
- Those who prefer an insecticide-based approach over physical (dimeticone) treatments
- Anyone completing a two-treatment course as recommended by the NHS
Children under 2 years should only be treated under medical supervision. If you are pregnant, breastfeeding, or have a known sensitivity to chrysanthemums or pyrethrins, speak to your pharmacist before use.
How Does Lyclear Creme Rinse Compare to Other Head Lice Products?
| Feature | Lyclear Creme Rinse 1% | Dimeticone (e.g. Hedrin) |
|---|---|---|
| Active ingredient | Permethrin 1% w/w | Dimeticone 4% or 92% |
| Mechanism | Neurotoxic — disrupts nerve channels | Physical — coats and suffocates lice |
| Application time | 10 minutes | 8 hours (overnight) or 15 minutes depending on formulation |
| Suitable from | 6 months (with caution under 2 years) | 6 months |
Is Lyclear Creme Rinse Suitable for Sensitive Scalps?
If you or your child has a sensitive scalp, it's worth knowing that mild irritation after using a head lice treatment is not unusual. Lyclear Creme Rinse is applied for just 10 minutes before rinsing, which limits prolonged skin contact. However, if there is broken skin, eczema, or a known allergy to permethrin or chrysanthemum plants, you should avoid this product and speak to your pharmacist about alternatives. You might also find it helpful to explore our skin care collection for products that support scalp health alongside treatment.
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.

- Temporary redness of the scalp
- Mild burning or stinging sensation during application
- Tingling of the skin
Less common side effects:
- Rash or skin redness beyond the scalp
- Swelling of the scalp or face
- Eye irritation if product contacts the eyes — rinse immediately with water

Frequently Asked Questions
Where can I buy Lyclear Creme Rinse Twin Pack online in the UK?
You can buy Lyclear Creme Rinse Twin Pack 2 x 59ml directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for £11.99. It is available without a prescription as an over-the-counter medicine. Browse our full head lice collection to compare all available treatments.
How does Lyclear Creme Rinse work in the body?
Lyclear Creme Rinse contains permethrin 1%, a synthetic pyrethroid that disrupts voltage-gated sodium channels in the nerve cell membranes of head lice. This causes continuous nerve firing, leading to paralysis and death of the louse. It acts locally on the scalp and hair and is not significantly absorbed into the bloodstream at the concentrations used.
How do I use Lyclear Creme Rinse step by step?
Wash hair with a non-conditioning shampoo, towel dry until damp, then apply the creme rinse generously from roots to tips. Leave on for 10 minutes, rinse thoroughly, and comb through with a fine-tooth nit comb to remove dead lice and eggs. Repeat the full process after 7 days using the second bottle in the twin pack.
Why does the twin pack contain two bottles?
The two-bottle format is designed to support the recommended two-treatment course for head lice. The first application kills live lice, but some eggs (nits) may survive. The second application, given 7 days later, targets any lice that have hatched from those eggs before they can lay new eggs themselves.
Is Lyclear Creme Rinse safe for children?
Lyclear Creme Rinse is suitable for children aged 6 months and over, though children under 2 years should only be treated under medical supervision. Always avoid contact with the eyes and mouth during application. If your child has a sensitive scalp or skin condition, speak to your pharmacist before use.
What is the correct dose of Lyclear Creme Rinse?
There is no fixed volume dose — you should apply enough product to thoroughly cover all the hair and scalp from roots to tips. For longer or thicker hair, more product will be needed. The treatment time is always 10 minutes regardless of hair length, and the process is repeated after 7 days.
What are the side effects of Lyclear Creme Rinse?
Common side effects include mild scalp itching, redness, tingling, or a temporary burning sensation during or after application. These are usually short-lived and resolve once the product is rinsed off. Stop use and seek medical advice if you experience swelling, a spreading rash, or difficulty breathing, as these may indicate an allergic reaction.
How do I manage side effects of Lyclear Creme Rinse?
Mild irritation usually settles on its own after rinsing the product out thoroughly. If the product contacts the eyes, rinse immediately with plenty of cool water. For persistent scalp redness or irritation, speak to your pharmacist — they may suggest a soothing scalp product from our skin care collection to use after treatment.
Can I use Lyclear Creme Rinse if I am pregnant or breastfeeding?
If you are pregnant or breastfeeding, you should speak to your pharmacist or GP before using Lyclear Creme Rinse. The NHS recommends wet combing as the preferred first-line option during pregnancy, as it avoids any chemical exposure. Your pharmacist can help you choose the most appropriate approach for your situation.
Who is eligible to use Lyclear Creme Rinse?
Lyclear Creme Rinse is suitable for adults and children aged 6 months and over who have a confirmed head lice infestation. It is not suitable for those with a known allergy to permethrin, pyrethroids, or chrysanthemum plants. People with asthma, eczema, or psoriasis affecting the scalp should seek pharmacist advice before use.
What happens if I only do one treatment and skip the second?
Skipping the second treatment significantly increases the risk of reinfestation. Head lice eggs that survive the first application can hatch within 7–10 days, and the newly hatched lice will not have been exposed to the treatment. Completing both applications as directed is essential for effective clearance of the infestation.
What are the alternatives to Lyclear Creme Rinse for head lice?
Alternatives include dimeticone-based products such as Hedrin, which work by physically coating and suffocating lice rather than using an insecticide — useful if resistance to permethrin is suspected. Wet combing with a fine-tooth nit comb and conditioner is a non-chemical option recommended by the NHS. Your pharmacist can advise on the most suitable choice for your circumstances.
Can head lice become resistant to Lyclear Creme Rinse?
Permethrin resistance in head lice has been reported in some parts of the UK and internationally. If you complete two full treatments correctly and still find live lice 24–48 hours after the second application, resistance may be a factor. In this case, speak to your pharmacist about switching to a product with a different mechanism, such as a dimeticone-based treatment.
How long does it take for Lyclear Creme Rinse to work?
Permethrin begins acting on lice within minutes of contact, and most live lice will be dead by the time you rinse the product off after 10 minutes. You may still see dead lice in the hair after rinsing — this is normal and they can be removed with a nit comb. The full two-treatment course over 7 days is needed to address the complete lice life cycle.
What are the latest findings on permethrin head lice treatments?
Current NHS guidance continues to recommend insecticide-based treatments including permethrin as one of the main options for head lice, alongside dimeticone and wet combing. Research has highlighted growing permethrin resistance in some lice populations, which is why the NHS advises checking for live lice after treatment and switching products if the first-line treatment fails. Always follow up with a pharmacist if treatment does not appear to be working.
