How to use
- Derbac M Liquid should be applied to dry hair. Make sure to shake the bottle well before using. Apply it onto the entire scalp, ensuring that the scalp is thoroughly wet with the liquid. Massage it particularly well behind the ears and the nape of the neck.
- Leave the liquid to dry naturally. Do not use a hairdryer. Allow Derbac M to remain in contact with the skin or scalp for 24 hours.
- After 24 hours, wash the hair with a non-medicated shampoo, rinse thoroughly and dry in the normal way.
- Although a single application is usually sufficient for head lice, for body lice or pubic lice a second application is necessary seven days after the first, in order to kill newly hatched lice.
- For scabies, mites and crab lice, a second application should be made after 24 hours.
- Before re-application, wash and dry the skin.
- Always read the package leaflet before use and strictly follow all the directions given by the doctor or healthcare provider. Do not use more than directed.
- Consult with your healthcare provider if symptoms do not disappear after the directed use.

You are getting the exact same genuine products you would find in a high-street pharmacy or premium clinic.
While our premium skincare and General Sales List (GSL) items can be added straight to your cart, certain treatments are classed as Pharmacy-only medicines. To ensure these are safe and appropriate for you, our pharmacists require a quick, confidential online consultation before approving your order.
Yes. We understand that your health and beauty concerns are private. All orders are shipped in plain, unbranded packaging with no indication of the contents or the pharmacy name on the outside of the box.
We offer two fully tracked and secure delivery options. Standard Shipping is £4.99, and Express Shipping is £7.99. Regardless of the delivery speed, all orders are carefully packed and dispatched in plain, discreet packaging to completely protect your privacy.
For safety and hygiene reasons, and in compliance with UK pharmacy regulations, we cannot accept returns on any dispensed medicines (including Pharmacy-only treatments), even if they are unopened. However, unopened and unused beauty and skincare products can be returned within 14 days.
