Mayonnaise
Mayonnaise is an excellent lice treatment because it’s so rich. Leave mayo in hair for at least an hour (up to 24 hours) or overnight. It’s best to leave the mayo on while someone sleeps since they won’t have to worry about it dripping into the eyes if they sleep. Mayo is a known home remedy for lice. It is used primarily as a protective barrier between the live lice and the hair shaft because it effectively seals the lice away from moisture. It prevents the lice from being able to feed, which is crucial for their survival. The mayonnaise must be left on the head for at least 6 hours, which can be done overnight or at work. It causes the lice to die because they cannot feed, and the oil strips off their protective layers of wax in the mayonnaise.
If you want an extra layer of protection, you can also use olive oil instead of mayonnaise. Both oils have similar effects, but olive oil dries out faster than mayonnaise, so they need to apply it more often. If they use olive oil instead of mayonnaise, they will want to leave it on for only 3 to 4 hours at a time.
