6. Use mayonnaise to kill head lice
Many dermatologists now recommend using mayonnaise to kill and remove head lice from kids instead of toxic prescription drugs and over-the-counter preparations. What’s more, lice are becoming more resistant to such chemical treatments. To treat head lice with mayonnaise, massage a liberal amount of mayonnaise into the hair and scalp before bedtime. Cover with a shower cap to maximize the effect. Shampoo in the morning and then use a fine-tooth comb to remove any remaining lice and nits. To completely eradicate the infestation, repeat the treatment in 7-10 days.
