no....you should use good shampoos for killing lice. You might get some but remember the nits (eggs) are way down near the root, so you have to contend with them to get it to go away.
same as with hair
yes
no, you need a special shampoo to kill lice.
First... vinegar does not kill lice. Use a proper lice shampoo.
Probably.
Hot water will kill public lice on clothing, but hot water and alcohol won't kill pubic lice in your pubic hair.
It will not hurt anything but it will not help with the lice.
Pyrithione zinc is not typically used as a treatment for lice. Products containing pyrethrin or permethrin are commonly recommended to kill lice. It is important to consult a healthcare provider for proper lice treatment.
I had lice. I put lemon juice in my hair to lighten my hair & I heard that it removed lice. I wet my hair in lemon juice. I blow dried it & repeated. I then washed my hair with cold water & conditioner. Sure enough, I saw dead lice come out. Gross yet effective!
The mature, grown, lice will leave eggs or nits in the hair. those eggs will hatch and turn into mature, grown, lice. This process with keep repeating until you get all lice and lice eggs out of the hair!
Hair Food is, as far as I can tell, the brand name of a hair care product by Jell Pharma. It's not designed to kill lice; if it really could do this and could keep them from returning, then I feel certain they'd advertise the fact on their website. It's possible that it could kill lice by smothering them, but this certainly wouldn't be a lasting solution; nowhere near as effective as real lice treatments like RID and similar products.
Though there is scientific evidence to support that heat will kill head lice, the risk of possibly scalding the scalp with the flat iron is a risk. Lice lay their eggs very close to the scalp. Nits usually hatch by the time the hair has grown 1/4 inch.
