While there is some controversy about this question, it is a fact that it takes longer for the chemicals to break through dirt to perform the reaction desired. If the hair is not too dirty, the dirt will help protect the scalp from the sometimes harsh reaction to the skin. "Too dirty" is a relative term, and includes styling products and processes.

If your hair has been washed within 3 days and you have not used a whole can of hairspray on it, then you do not need to re-wash your hair prior to coloring it. It will not affect the chemical process.

They say when you're hair is dirty the hair color comes out better. But maybe they mean by when you've put some products in your hair or something, and haven't washed it in like a day or so.
When its dirty! When you apply dye to the newly washed hair shaft it WILL take BUT by washing it you have stripped it of all its natural oils WHICH is better to have present on the hair in order for the dye to adhere easier. If you've ever had your hair dyed at a salon you'll have noticed that they NEVER EVER wash the hair first, they just start applying it no matter WHAT dirt or products have built up on it. So nevermind what the over-the-counter drug store hair dye instructions recommend, DIRTY is better!!!

Dandruff is a skin condition of the scalp that causes flakes to appear and is marked by itching. When your body renews the skin cells in your scalp, the old, dead ones are pushed to the surface. In some people, the body renews the skin cells too frequently for the old ones to be shed inconspicuously, causing a mass amount of dead skin to gather on the scalp, resulting in the condition known as dandruff.

Nits are head lice eggs. Coincidentally, having head lice can actually cause or increase flaking of the scalp, resulting in or worsening a case of dandruff. You can recognize nits because they are attached to the hairshafts and are usually present closer to the scalp. They do not comb out easily, and even when pinched between two fingers and tugged on may still be difficult to remove.

Dandruff, on the other hand, comes out easily and is flat. If you can scratch your scalp gently or brush your hands through your hair and white flakes fall out, it is dandruff. If there are white spots clinging to your hair and you cannot seem to remove them, they are most likely nits.

Not likely. Exterminators are not equipped to deal with insects that live on the human body, but rather insects and pests that live within the home. Even if an exterminator WERE equipped to do such things, if even one person in your household has one living lice on them, it is possible for that one bug to re-infest your entire home.Therefore, I would say no. An exterminator cannot get rid of lice. However, you can do it quite easily (and very cheap) simply by washing all of your bedding and clothing, vacuuming your carpets and furniture (anything with a cloth on it as well as curtains if you have small children in your home), the seats in your vehicle, and any stuffed animals, headphones and helmets you may have. Head lice can survive for up to 24 hours off of the human head, mostly on cloth or fur surfaces as well as soft styrofoam and materials of the like.

Run these items through the dryer as well for an extended period of time, as lice and nits will die when exposed to temperatures equal to or over 138 degrees Fahrenheit. Be sure to boil all of your brushes, combs and hair clips in a pot of hot water thoroughly, as well as saturate your hair with dawn dish soap, mayonnaise, or olive oil (they are all very effective and cheap, though sometimes difficult to wash out.) It would be best to leave whichever one you use in for two hours with a shower cap, which you can pick up at most beauty stores for a dollar or so, but you can also simply tie a grocery bag around your head! (WARNING: DO NOT USE VASELINE OR PETROLEUM JELLY ON YOUR HAIR. IT IS NEARLY IMPOSSIBLE TO WASH OUT. Petroleum jelly/vaseline is meant to lock out moisture to prevent chapping or raw skin, meaning that even if you try to wash it out of your hair, moisture will not penetrate it well.)

While it's suffocating the lice and nits, do your vacuuming and washing of beddings, furniture, etc. and then wash it out. Comb through your hair thoroughly afterward with a lice comb.

There is no reason anyone should be asking this or DOING this.

I got razor burn from shaving and so i rubbed rubbing alcohol in the vaginal area and after a few days of doing so i got blisters, I'm looking for an answer to this question also.

It would hurt like mad, it is for sore muscles not delicate mucous membranes.

ANSWER:

Use an over the counter hydrocortisone cream instead. NO alcohol wipes/rubbing alcohol.

You are thinking along the lines more regarding ticks. No, it wouldn't make a difference and you should see your doctor who will give you medication for this. Children can come home from school with lice in their hair and it's contagious. With the proper medication (generally a medicated shampoo) you can get rid of the lice quite quickly. It's important the whole family shampoo their hair.

I am a Nurse Practitioner. In answer to your question, yes, in theory, vaseline could kill lice. It would smother them. But you would have to put it over your entire head and all the hair. It would be messy, sticky and hard to get the nits out. It is better to use mayonnaise. I have recommended this to patients before for stubborn lice infestations. It washes out better than vaseline and makes it so the nits slip out. Put the mayonnaise on at night. Cover the entire head. Cover with saran wrap or shower cap. Sleep with it on head. Wash hair in the morning. Be sure to comb out all nits with a good nit comb. Nit combs can be bought at your local drug store.

Vaseline can kill lice, but it's use is really messy and hard. I will suggest you to use Cetaphil for the treatment of Head Lice. Cetaphil is easy to use and can remove all the lice from your head in just one wash. Cetaphil is a famous treatment for head lice problem. you can order Cetaphil from Chemist Direct to enjoy a great discount on it.
Cetaphil should be gently applied to your entire head and than it should be left to dry, you can also use hair dryer to dry it. After drying you should wash your head with a good shampoo and comb your hair. Cetaphil is really a good solution to remove lice from your head.

In Spain because the land level is higher. You can tell this by looking at a physical map.
