Immediate Steps

Effectively killing fleas on humans involves the use of safe, skin-friendly treatments.

Safe Treatments

  • Diatomaceous Earth: Food-grade diatomaceous earth can be applied to dry hair and scalp to dehydrate and kill fleas. Ensure you wear a mask to avoid inhalation and rinse thoroughly after use.
  • Essential Oils: Essential oils, like tea tree, lavender, and eucalyptus, can repel fleas when diluted with a carrier oil and applied to the hair and scalp. Perform a patch test to prevent allergic reactions.

Environmental Control

  • Clean and Vacuum: Regularly clean and vacuum your living spaces to remove fleas from the environment.
  • Pet Treatment: Ensure pets are treated for fleas to prevent cross-infestation.

Preventative Measures

Preventing flea infestations in human hair involves both personal and environmental hygiene.

  • Regular Washing: Keep your hair clean and shampoo regularly to create an inhospitable environment for fleas.
  • Avoid Infested Areas: Stay away from areas known to be infested with fleas, especially if you have pets that go outdoors.
