Level of infestation

• A light infestation (few lice, minimal eggs) is faster to treat than a heavy, long‑standing one where the hair is full of eggs at different stages. Heavier infestations take longer to comb through thoroughly, so they cost more.

Hair length and thickness

• Long, thick, curly or very dense hair simply takes longer to work through section by section. Clinics often estimate treatment time based on hair type when you book, and some may have different price bands for short/medium/long hair.

Number of family members

• If several siblings – or the whole household – are affected, most clinics will either charge per person or offer a family package. Per‑person rates may look high, but a family bundle (where everyone is checked and treated in one visit) can be more cost‑effective.

Clinic vs home visit

• Some providers have fixed locations; others offer mobile visits where a specialist comes to your home. Home visits can be more convenient, especially with younger children or those with additional needs, but there is usually a call‑out or travel charge included.

Follow‑up appointments

• Many professional services recommend at least one follow‑up check to ensure that no new lice have hatched and that you remain clear after the initial treatment. Follow‑ups may be included at a reduced rate or bundled into a package price.

What do you get for the money?

• At first glance, professional treatment can look more expensive than picking up a bottle from the pharmacy. But the price covers more than just a product. A reputable London head lice clinic will typically include:

A thorough head check

• Each person’s scalp and hair are examined carefully, usually with a fine‑toothed nit comb and good lighting. This confirms whether live lice or eggs are present and how severe the infestation is.

Professional removal technique

• Instead of relying only on chemicals, many modern clinics use intensive manual combing with specialist products and tools designed to break the lice’s grip and remove eggs. This meticulous approach is the main reason for higher success rates.

High‑quality, child‑safe products

• Professional treatments often use non‑toxic or low‑toxicity formulas designed for sensitive skin and repeated use. For children with asthma, eczema, or allergies, this can make a big difference.

Education and prevention advice

• You’ll usually be shown how to check for lice at home, how to use a nit comb properly, what to wash (and what you don’t actually need to disinfect), and how to reduce the risk of re-infestation from school, friends, or siblings.

Peace of mind and follow‑up

• Knowing that the lice and eggs have been removed properly, and having the option of a follow‑up check, can dramatically reduce the cycle of constant re‑treating and anxiety many families go through.
