Even humans can find fleas in their hair; but there are many home remedies you can use to treat them. It's vitally important that you treat your environment, too, because the fleas will come right back if they're around. You may need to treat three or more times to ensure that all fleas and eggs are dead, and continue to treat any pets that live with you to prevent future re-infestation.
Mix 1 tbsp. baking soda with 2 cups clean, warm water in a spray bottle. Shake this very well. Make sure you use a brand-new spray bottle; there may be chemical residues from previous household tasks in a used one.
Spray your hair thoroughly with the baking soda-water mixture. Avoid your eyes. Rub the baking soda into your hair and apply the shower cap. Wait 15 minutes for the baking soda to work on the adult fleas and their eggs.
Rinse the baking soda out of your hair with plenty of warm, running water. Comb from your roots to your ends with the fine-toothed comb and rinse again. You're attempting to extract all dead bodies and any eggs that may be clinging to the hair shafts.
Wash your hair with lemon-scented dish soap. Don't use dishwashing detergent made for dishwashers. Apply the soap generously and lather completely. Massage the scalp with the fingertips to loosen any eggs that may be hiding at the roots. Rinse completely. Comb with the fine-toothed comb from roots to ends and repeat at least one more time.
After another complete rinse with clear, warm water, comb again. Apply apple cider vinegar to your hair to soak. Put on the shower cap and again wait 15 minutes. Before rinsing, comb the vinegar through your hair. This step changes the acidity of your hair and scalp, making it difficult for fleas to live in the new environment.
Do a final rinse. Dry your hair with a clean towel and start de-bugging your home. Attack the fleas at their source--usually your pet--and repeat the attack in seven to 10 days after their remaining eggs have hatched.
Prevent another hatching by placing a flea collar in your vacuum cleaner bag. Fleas get into everything, so you must de-flea every nook and cranny of your home and eliminate them at the source (usually pets). This may require a professional treatment by a licensed exterminator.
Don’t repeat this hair washing process more than every other day; you will damage your hair and scalp if you overdo it.
