Derbac M is a treatment for head lice and nits which can also be used to treat pubic lice and scabies. It can be used by anyone over the age of 6 months old, making it ideal for all the family. Derbac M does not contain alcohol, which may make it more suitable for those who suffer from asthma or eczema.

Derbac M uses the active ingredient malathion, which kills head lice, nits, pubic lice and scabies mites. It blocks a natural enzyme in the nit or mite, stopping it from growing and leading to their death.

Melathion 0.5% w/w

If you are treating head lice, apply enough Derbac M liquid to dry hair that no part of the scalp is left uncovered.

Work the liquid into the hair with your fingers, making sure it is spread evenly from root to tip.

Leave hair to dry naturally in a warm, well-ventilated room.

After 12 hours, shampoo the hair as you usually would, then rinse the hair and comb with a nit comb while wet.

This should remove head lice and nits. Repeat treatment after 7 days if necessary.

How to use:

Apply Derbac M to the entire surface of the skin. If you are an adult, you may not need to apply this product above the neck, but if you are treating a child aged 6 – 24 months then you should apply ta thin film of this liquid to their scalp, face, and ears.
