This is how my abuela used to do it. Wet the hair and cover it with conditioner or something oily. Comb from the scalp all the way through the hair removing lice and nits along the way. Do the entire head twice. Wash hair.
Repeat the process daily until no nits or lice are found.
Mash up about 10 cloves of garlic and mix with the juice of 1 lime. Rub the mixture throughout the scalp. Let sit for half and hour and then rinse with warm water.
Baby oil 3
For this method you will need baby oil, laundry detergent and white vinegar. You put baby oil on your scalp and hair and use a nit comb to get the lice and nits out. When you are done, wash your hair with a bit of laundry detergent and hot water. At night before going to bed pour some white vinegar on your hair, leave it in and sleep with your head covered in a shower cap. The next morning shampoo and condition as you normally would.
Butter applied to your hair and scalp will deprive nits and lice of oxygen as well. You would apply the butter to hair and sleep with it overnight.
You want to use the real mayonnaise in this case, not some light version. You cover the scalp and hair in mayonnaise and wrap it up in a shower cap or towel and sleep with it overnight that way. The next morning you shampoo your hair as usual. The theory is that all that fatty oils in mayo suffocate the critters.
Petroleum jelly 7
Petroleum jelly is a staple in many Latino households and can be used to get rid of lice just like all of the other smothering agents discussed. Put a thick coat of it on the scalp before going to bed and wrap in a shower cap. The next morning you wash it out. Use baby oil to help you get the petroleum jelly off before shampooing.
White wine vinegar 8
The acid in vinegar helps get rid of lice. Cover your hair and scalp in white wine vinegar, then wrap it up in a shower cap for a couple of hours. Follow up by combing through hair from scalp to tips to remove lice and nits. Shampoo as usual and you can follow up with another rinse of vinegar after shampooing.
Okay, so I've been told and I've read that Listerine Antiseptic Mouthrinse is a great tool for removing lice. Cover head and scalp with it, be careful not to get it in eyes, wrap hair up in a shower cap for two hours, wash hair when done.
