Does Dying Your Hair Kill Lice?

The idea that hair dye can kill head lice has circulated for some time. While hair dye contains chemicals that may potentially affect lice, it’s crucial to understand the extent of its efficacy:

  • Chemical Composition: Many hair dyes contain ammonia and hydrogen peroxide, which could potentially harm lice. However, the primary purpose of these chemicals is to alter hair color, not to kill pests.
  • Lice Resilience: Head lice are resilient creatures. While hair dye may kill some lice, it’s not a guaranteed or medically approved method for lice removal.

Considerations for Dyed Hair

For those with dyed hair facing a lice infestation, traditional lice treatment methods are still recommended:

  • Use of Lice Treatments: Over-the-counter lice treatments specifically designed to kill lice and their eggs are more reliable than relying on hair dye.
  • Consultation with Professionals: Seek advice from healthcare professionals or lice treatment specialists when dealing with lice in dyed hair.

How to Get Rid of Lice with Dyed Hair

Managing lice in dyed hair requires careful consideration to avoid damaging the hair further:

  • Gentle Treatment Options: Opt for lice treatments safe for dyed hair, ensuring they don’t strip or alter the hair color.
  • Natural Remedies: Some may prefer using natural remedies like tea tree oil or coconut oil, which can soothe the scalp and potentially aid in lice removal without affecting hair dye.

What Will Kill Lice Eggs?

Eradicating lice eggs (nits) is a critical step in completely removing a lice infestation:

  • Manual Removal: Using a fine-toothed nit comb to remove nits from the hair shaft manually is one of the most effective methods.
  • Essential Oils: Certain essential oils have been touted for their potential to loosen nits, though scientific evidence is limited.
  • Repeat Treatments: Many lice treatments require multiple applications to eliminate all live lice and nits.


Dyeing your hair may affect head lice, but it is unreliable or recommended for treating lice infestations. Traditional and medically approved lice treatments, diligent combing, and proper hair care remain the most effective strategies for combating head lice.

If you have dyed hair and are dealing with lice, focus on safe treatments for colored hair and consult professionals for guidance.
