In one sentence, describe what the following article is about: Vinegar is a common home remedy for head lice, but some people mistakenly think it will kill adult lice and their eggs, which are called nits. In reality, vinegar cannot kill head lice directly because it's not toxic to them. However, it can help remove the nits stuck to your hair, which prevents new lice from hatching and infesting your head. More specifically, the acetic acid in vinegar dissolves the protective shells surrounding nits and disables them from sticking to your hair. After the application of vinegar, the nits either fall out of your hair or become much easier to remove with a fine-toothed comb. Although vinegar can't kill adult lice, they may be able to kill newly hatched lice called nymphs. More research is needed to better understand the impact of vinegar or acetic acid on head lice. Since vinegar will not kill the lice and eggs, it is important to treat the lice with a medicated shampoo first. Lice treatment shampoos are also known as pediculicides. After using a pediculicide, you can use vinegar to help remove the nits from your hair. Using a medicated shampoo first will help to ensure that the adult lice are dead and this will reduce the chances of spreading the lice. All types of vinegar contain acetic acid, but some types and brands are a little more concentrated than others. In general, chose a vinegar that has about 5% acetic acid it's enough to dissolve the coatings on nits, but not acidic enough to irritate most people's skin. White vinegar is plain acetic acid diluted in water and usually the least expensive choice. Red wine vinegar is more expensive and often has between 5-7% acetic acid. Apple cider vinegar will also work, but make sure to choose non-filtered and pasteurized types because they tend to be the strongest concentration (around 5% acetic acid). A much higher concentration of acetic acid (more than 7%) might irritate your scalp, although much weaker concentrations might not be able to dissolve the nits attachment to you hair. Stick to vinegars that have between 5-7% acetic acid. The itching from head lice is due to an allergic reaction to lice saliva. Not all people have an allergic reaction and get itchy. Once you've decided on the type and concentration of vinegar, undress yourself and stand in the tub or shower. Dampen your hair with some water first (but not too much so that it's dripping wet) and then pour on a few cups of vinegar directly to your scalp. Massage the vinegar into your scalp and try to cover as much of your hair as possible this might be challenging if your have long hair, but take your time. Then, let the vinegar sit in your hair for between 5-10 minutes, which is enough time for it to dissolve the nit's exoskeletons (coverings). Make sure to close your eyes when you apply the vinegar. Diluted acetic acid can't damage your eyes, but it can certainly make them sting for a few minutes. Avoid getting vinegar on your clothes because it can stain them, particularly red wine and apple cider vinegars. After the vinegar has been in your hair for at least 5 minutes, run a fine-toothed comb through it thoroughly. The loosened nits and some adult lice will be removed by intensive combing. For best results, consider buying a special "nit comb" (very fine-toothed plastic or metal combs) at the pharmacy or online. After combing your hair for a few minutes, rinse out the remaining vinegar and towel dry it but make sure not to share your towel with anyone while you still have some head lice. Using vinegar is great for loosening nits from your hair, but not for killing mature lice on your scalp. Thus, don't be surprised to see some head lice after a vinegar treatment. Vinegar treatments can be done daily until no more nits remain attached to your hair. The acetic acid will also remove the oils from your hair, so it might look dry or frizzy after the vinegar treatments. Nits hatch within 7-9 days of being laid, and mature lice can live up to 3-4 weeks. Thus, if you're just using vinegar to combat your head lice, it may take a month before the infestation is completely gone.
Summary: Understand the benefits and limits of using vinegar. Use an over-the-counter medicated shampoo first. Choose the type of vinegar. Stand in the shower or tub and apply the vinegar. Run a fine-toothed comb through your hair.

In one sentence, describe what the following article is about: Before reschedule your job interview, try to rearrange your other plans instead. Your job interview serves as a first impression for a potential employer, so rescheduling may come off as unprofessional. If possible, rearrange the other parts of your schedule before rescheduling your job interview. Rescheduling a job interview can be a huge inconvenience to everyone involved. Because of this, it's important that you contact your potential employer to reschedule at least 24 hours before your scheduled interview. When you contact your interviewer, give a brief explanation for your need to reschedule. Be as honest as possible. Give your interviewer a few alternative dates that will work for your rescheduled interview. If you're rescheduling due to another job interview, it's best not to tell your interviewer that. Tell them you've had a work or family conflict come up, and that you'd love to reschedule your interview for another time. If a life emergency happens and you cannot give 24 hour notice, contact your interviewer as soon as possible to let them know what happened. If it's a real emergency (you were injured, you have a family emergency, etc.), your potential employer should understand. If you're still interested in the job, express that when you call to cancel. Say something like "I'm very sorry, but an emergency has come up and I won't be able to make our interview tomorrow. I'm still interested in the position and would be extremely grateful if we could reschedule." When possible, make direct contact with your potential employer instead of sending an email or leaving a message. Making contact via phone will make you look like a responsible professional. Make an effort to get in touch with your interviewer in numerous ways, and only leave a message or send an email if you cannot reach them via phone. Never send a text message to reschedule an interview, as it will make you look unprofessional. If you end up leaving a message or sending an email, ask that your interviewer contact you to confirm they got your message. A job interview is normally scheduled around multiple people's schedules. Therefore, cancelling or rescheduling an interview is usually an inconvenience for multiple people. Don't assume that your interviewer's schedule revolves around you, and apologize for causing any inconvenience. Try to be flexible when you ask to reschedule your interview. If your interviewer sees that you are putting in good effort to make this interview work, they will be more likely to reschedule your interview. After you've contacted your interviewer about rescheduling, send them a personal note or email reiterating your apology and your interest in the company. Your interviewer may be frustrated or irritated by you cancelling, so use this note as an opportunity to let them know that you are genuinely sorry and would still like a chance to reschedule an interview.
Summary:
Reschedule your job interview only as a last resort. Contact your interviewer with as much notice as possible. Speak with your interviewer directly, do not leave a message. Apologize for the inconvenience. Send a follow up note to your interviewer.
