- Head Lice & Nits Treatment Treherbert | NHS Pharmacy Advice
If you are looking for head lice treatment in Treherbert, Treherbert Pharmacy may be able to help through the NHS Wales Common Ailments Service.
Head lice are small insects that live close to the scalp. Nits are the empty egg cases left attached to the hair, so nits or itching alone do not prove that treatment is needed. A live moving louse must be found to confirm an active infestation.
People aged 6 months and over may be eligible for a free NHS pharmacist consultation and free treatment where clinically appropriate. You can approach or book with the pharmacy directly and do not need a GP referral first. If possible, bring evidence of a live louse attached to clear sticky tape.
Choose an NHS appointment if you would like help with this condition. The pharmacist will assess whether treatment is suitable or whether you need another service.
What are head lice and nits?
Head lice are grey-brown insects, about the size of a sesame seed when fully grown, that live in the hair and feed from the scalp. They spread mainly through close head-to-head contact and can affect adults as well as children.
Nits are empty yellow-white egg cases that remain firmly attached to individual hairs after the lice have hatched. They may stay in the hair for months and do not, by themselves, mean that live lice are still present.
Head lice are not caused by dirty hair. They can live in clean or unwashed hair, and having them is not a sign of poor hygiene.
Signs people often notice
- Live lice in the hair: small moving insects found close to the scalp, often behind the ears or around the back of the neck.
- Itching: the scalp may itch, although some people with live lice have no itching at all.
- A moving or tickling feeling: some people notice the sensation of something moving through the hair.
- Nits attached to hairs: white, yellow or brown egg cases that do not brush away like dandruff.
- A rash behind the ears or at the back of the neck: this can occur as a reaction to the lice.
- Scratch marks or a sore scalp: repeated scratching can damage the skin and occasionally lead to infection.
The only reliable way to confirm active head lice is to find a live moving louse. Wet detection combing with conditioner is usually more accurate than checking dry hair.
Can Treherbert Pharmacy help with head lice treatment?
The NHS Common Ailments Service can usually assess confirmed head lice in adults and children aged 6 months and over. The pharmacist will check that the diagnosis is clear and that the proposed treatment is suitable for everyone who needs it.
CAS may be suitable when
- The person needing treatment is aged 6 months or over.
- A live moving louse has been found using a detection comb.
- There is no marked scalp inflammation or sign of infection.
- An appropriate wet-combing method or head lice product can be used safely.
Another assessment route may be needed when
- The baby is under 6 months old.
- Only nits or itching have been found and no live louse has been seen.
- The scalp is very inflamed, broken, crusted, weeping or appears infected.
- Live lice remain after appropriate treatments have been completed correctly.
- The diagnosis is uncertain or a treatment may not be suitable because of age, pregnancy, breastfeeding, asthma, eczema or another clinical factor.
If you have found a live louse, attaching it to a small piece of clear sticky tape and bringing it to the consultation can help confirm the diagnosis. Treatment products should not be used “just in case” or to prevent head lice.
What happens during your consultation?
-
Confidential assessment. The pharmacist will discuss who has been affected and how live lice were identified.
-
Diagnosis check. Evidence of a live louse will be considered. If the diagnosis is not yet confirmed, the pharmacist can explain how to use a detection comb correctly.
-
Suitability review. Age, pregnancy or breastfeeding, asthma, eczema, allergies, scalp condition and previous treatments will be checked.
-
Treatment plan. Wet combing or a suitable head lice treatment may be recommended or supplied where clinically appropriate, with clear instructions for application and repeat treatment.
-
Household and follow-up advice. Everyone who lives with or has close contact with the affected person should be checked, and anyone with live lice should be treated on the same day.
What information may the pharmacist ask about?
- Who has live lice, their ages and whether everyone in the household has been checked.
- When and how a live louse was found, and whether evidence can be brought to the consultation.
- Whether there is scalp redness, broken skin, crusting, weeping, swelling, pain or pus.
- Previous wet-combing sessions or head lice products, including the dates, application method and whether repeat treatment was completed.
- Hair length and thickness, because enough product is needed to cover the scalp and all hair from roots to tips.
- Pregnancy or breastfeeding, asthma, eczema, allergies and any previous reaction to a treatment.
- Whether the affected person or close contacts have been treated at the same time, as untreated live lice can cause reinfestation.
How is head lice treatment managed?
The most suitable option depends on the affected person’s age, treatment history, hair, preferences and any clinical cautions. The pharmacist may discuss:
- Wet combing: systematic combing of shampooed, conditioned wet hair with a fine-toothed detection comb. A full course normally involves repeated sessions on the recommended days.
- Physical head lice treatments: a lotion, spray, gel or other product that acts physically on lice and is suitable for the person being treated.
- Alternative treatment after failure: a different option may be considered after checking that the first treatment was applied in the right amount, for the correct length of time and repeated when required.
- Detection combing after treatment: this checks whether any live lice remain. Nits or continued itching alone do not necessarily mean treatment has failed.
Important treatment safety
- Follow the product instructions exactly. Contact time and whether a second application is needed vary between products.
- Keep treated hair away from flames, cigarettes and other ignition sources. Some head lice products can remain flammable even after the hair appears dry and until it has been washed out.
- Do not use treatment to prevent lice. Medicated products should only be used when live lice have been confirmed and can irritate the scalp when used unnecessarily.
- Avoid unproven remedies. Essential oils, herbal treatments, repellents and electric combs are not recommended.
When our pharmacist independent prescriber may be able to help
Most confirmed cases in people aged 6 months and over should use the NHS Common Ailments Service first. If the condition falls outside that pathway but there are no urgent warning signs, our pharmacist independent prescriber may still be able to assess the affected person.
This may be relevant for a baby under 6 months, scalp inflammation or possible infection, persistent live lice after appropriate treatments, or uncertainty about whether the problem is head lice. Treatment can be prescribed where clinically appropriate, or we will explain whether GP or another healthcare service is needed instead.
An independent prescribing consultation does not guarantee treatment or a prescription. The safest route will depend on the person’s age, symptoms, examination findings and treatment history.
When you should seek urgent medical help
Head lice are not usually an urgent medical problem. Do not wait for a routine pharmacy appointment if a serious reaction or significant skin problem develops.
- Call 999 or go to A&E if a treatment causes difficulty breathing, collapse, severe dizziness, or swelling of the face, lips, mouth, tongue or throat.
- Seek urgent same-day advice from your GP or NHS 111 Wales for severe blistering, a suspected chemical burn, marked swelling or a severe reaction after using a head lice product.
- Seek same-day medical advice if the scalp has spreading redness, increasing pain, pus, significant crusting, or the person has a fever or feels generally unwell.
Practical advice for the household
- Check everyone who lives with or has close head-to-head contact with the affected person using a proper detection comb.
- Treat only people in whom live lice are found, and start their treatment on the same day to reduce reinfestation.
- Children being treated for head lice can continue to attend school or nursery.
- There is no need to hot-wash clothing or bedding or carry out extensive cleaning of the home.
- Do not share combs or brushes while live lice are present, and clean the detection comb after use.
- Itching may continue for days or weeks after successful treatment. Check for live lice rather than treating again because of itching or nits alone.
