Full Marks Head Lice Treatment Spray With Comb - 150ml

 

You can effectively tackle head lice infestations with this clinically proven solution that works by physically disrupting the lice lifecycle. The spray contains dimethicone, a silicone-based ingredient that coats lice and nits, preventing them from breathing and ultimately eliminating the infestation.

This treatment comes complete with a specially designed detection and removal comb to help you identify and remove dead lice and nits from your hair. The 150ml bottle provides sufficient solution for multiple applications, making it suitable for treating entire families when needed.

 

How This Lice Solution Works on Your Scalp

 

The dimethicone formula works by creating a coating around lice and their eggs, which blocks their breathing apparatus and causes them to suffocate. Unlike traditional insecticide-based treatments, this physical mode of action means lice cannot develop resistance to the treatment.

You apply the solution directly to dry hair, ensuring complete coverage from roots to tips. The treatment penetrates the hair shaft to reach lice hiding close to the scalp, whilst the included comb helps you systematically remove dead lice and nits after treatment.

 

Who Can Use This Head Lice Spray

 

This head lice treatment is suitable for adults and children over 6 months of age. You can use it safely during pregnancy and breastfeeding, as the dimethicone does not absorb into your bloodstream.

The treatment is particularly suitable if you:

  • Have sensitive skin that reacts to traditional insecticide treatments
  • Need to treat multiple family members simultaneously
  • Prefer a non-toxic approach to lice removal
  • Want a treatment that works regardless of lice resistance patterns

You should consider exploring our comprehensive Head Lice collection if you need additional products for prevention or ongoing management.

 

Why Choose a Silicone-Based Lice Treatment

 

Silicone-based treatments like this one offer several advantages over traditional insecticide formulations. They work through physical action rather than chemical toxicity, which means they remain effective even against lice populations that have developed resistance to conventional treatments.

The dimethicone formula is also gentler on your scalp and hair compared to harsh chemical alternatives. You can use this treatment without worrying about the strong odours or potential scalp irritation associated with some traditional lice shampoos.

 

Storage and Shelf Life Considerations

 

You should store this product at room temperature, away from direct sunlight and heat sources. Keep the bottle tightly closed when not in use to prevent the solution from thickening or losing effectiveness.

The treatment remains stable for the duration of its shelf life when stored correctly. Always check the expiry date before use and dispose of any expired product safely through your local pharmacy returns scheme.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

 

How to Apply Full Marks Head Lice Solution

You should apply this treatment to completely dry hair before washing. Part your hair into sections and spray the solution generously from roots to tips, ensuring you cover all areas of your scalp and hair thoroughly. Pay particular attention to areas behind your ears and at the nape of your neck where lice commonly hide.

Massage the solution gently into your hair and scalp to ensure even distribution. You need to leave the treatment on your hair for at least 8 hours or overnight for maximum effectiveness. This extended contact time allows the dimethicone to fully coat all lice and nits present.

Post-Treatment Hair Washing and Combing Instructions

After the required contact time, you should wash your hair thoroughly with your regular shampoo. You may need to shampoo twice to completely remove the dimethicone solution from your hair. Once your hair is clean and towel-dried, use the included detection comb to systematically comb through your hair in small sections.

You should repeat the entire treatment process after 7 days to catch any lice that may have hatched from eggs since the first application. This second treatment is essential for breaking the lice lifecycle completely and preventing re-infestation.
