What is Full Marks Solution Spray?

Full Marks Solution Spray is a pesticide-free treatment for head lice and nits. It’s a simple 10-minute treatment that’s easy to apply and effective in just one use. This product contains enough spray solution for 3 treatments and comes with a handy comb that can help you to remove nits and head lice from hair.


What are head lice and nits?

Head lice are tiny lice that can make their home on your hair and scalp, and nits are head lice eggs. Head lice are a common condition, especially in children, as they can be spread through head to head contact which happens when children play together. When you have head lice, you’ll often feel like your scalp is itchy, or like something is moving in your hair. If you look closely, you may be able to see the lice and nits clinging to your hair.


How will Full Marks Solution treat head live and nits?

Full Marks Solution works by dehydrating head lice and their eggs, killing them without using a pesticide. This spray also comes with a comb, so once you’ve used the treatment you can comb the lice and eggs from the hair, clearing the infestation quickly.


Can I use this spray if I’m pregnant or breastfeeding?

If you’re pregnant or breastfeeding, you should speak to your doctor or pharmacist before using this product. Some treatments may not be suitable for you at this time, and a medical professional can help you to choose a suitable product.


Can I use this product if I’m taking other medication?

If you’re using any medication, including those you obtained without prescription, you should speak to your doctor or pharmacist before using Full Marks Spray. Some products can interact when used together, making your medication less effective or causing unwanted side effects.


How to use this spray

Before using the spray, comb the hair with a normal comb or brush to remove any tangles. Then shake the bottle well and spray the Full Marks Solution all over the hair and scalp, making sure that the hair is fully coated. Leave the solution on the head for 10 minutes and then comb the hair again with the nit comb included with this treatment. For best results, treat the entire family at the same time.


When should this treatment not be used?

Full Marks Solution Spray is not suitable for use in children under the age of 2. Do not use this product if you are allergic to any of the listed ingredients. For external use only, avoid contact with eyes and other sensitive areas.
