In one sentence, describe what the following article is about: Nothing communicates maturity like confidence. Even if your physical appearance, unique personality, or social skills aren't what you wish they are, that doesn't have to stop you from building self-confidence. There's a fine line between being confident and being arrogant or condescending. Confidence is feeling good about yourself, not better than those around you. Don't excessively brag about your accomplishments or speak in a way that puts you above others. This is classic immature behavior. Slouching is another classic behavior associated with teens. Hold your head up high and straighten your back. Learn how to walk confidently and improve your posture. Start by standing up straight wherever you are, whether it is walking down the street, sitting at your desk, using a computer, or waiting in line. Correct yourself whenever you notice your posture faltering. Soon, it will become second nature. Changing the way you carry yourself goes hand-in-hand with confidence. Keep your head up high; don't stare at the ground. Look people in the eye when you talk. Speak slowly and confidently instead of loudly. Remember your manners by using "please" and "thank you." Listen closely to what others say; few things demonstrate maturity as much as a good listener. When people finish stories about themselves, don't immediately launch into a story about yourself. This makes you look self-centered and uninterested. Instead, react to their story first, then use your own story as a way of relating to the other speaker. Learn how to use small talk. Ask how people are doing. Talk about the weather. Ask about their families. Be polite and carry on light conversation with people. People who are always complaining come off as immature and self-centered. As you mature, you accept that things come and go, and that complaining is unlikely to assist you. Brooding about how awful your life is won't help you actually improve it. Venting to your friends can be beneficial for catharsis or to solicit advice, but constantly complaining about inconsequential occurrences is very juvenile. This doesn't mean dropping unnecessarily large words during everyday conversation, which will make you look desperate for attention. Focus on cutting out childish words that will clearly identify you as a teen. Speak slowly and deliberately. Make your words count by thinking about word choice. Learn some sophisticated vocabulary. A good place to start is with SAT vocabulary. For example, say, "That's a novel idea!" instead of "That's a new idea." Tell someone to be "candid" with you instead of honest. A more sophisticated vocabulary makes you look mature and intelligent. Try not to overuse slang. Avoid "like," screeching "Oh My God!," and punctuating sentences with "totally," "you know," and other meaningless fillers. Try not to use "awesome" and "dude." When texting, avoid typing in all capital letters, because it gives the receiver the impression that you are screaming, which is not something that is acceptable among adults in most situations. In addition to that, it is generally a good idea to use profanity in moderation, and avoid using it when it does not provide the receiver a further understanding of what you are saying. If someone disrespects you, feel free to tell them to stop. After all, part of maturity is commanding respect. Be straightforward and communicate what you want. Avoid using excessive sarcasm or acting extremely offended. Even if you're joking with these snarky comments, they make you look bad and won't achieve the results you're looking for. For example, if someone interrupts you, say, "Hold on, please don't interrupt me." Don't say things like, "Wow, I can't believe you just interrupted me. Someone doesn't know when to shut up!" Learn when to let things go. Everyone has negative encounters with others, but it takes wisdom to learn how to pick your battles. Being spiteful, resentful, or malicious will make you look immature. Learn the difference between venting to a close friend and putting someone down behind their back. Sometimes when people rub you the wrong way, they often don't realize it. Be respectful of their feelings by either ignoring the mistake or, if necessary, clearly communicating to them that they have caused offense.
Summary: Be confident. Change the way you physically carry yourself. Develop social graces. Complain less. Improve your vocabulary. Stand up for yourself politely but firmly.

In one sentence, describe what the following article is about: The sooner you catch and treat the damage, the better. The longer you wait before treating the damage, the more difficult it will be to repair. In some cases, you may have to resort to more extreme treatments, such as cutting your hair. Your hair care regime includes not only treatments, but also good habits, such as avoiding heat styling. Clarifying shampoo can help smooth and calm your hair when it's dry or crispy. If you can't find a clarifying shampoo, use a gentle shampoo instead, then rinse your hair with apple cider vinegar. Wash your hair no more than twice per week. Skip the hot water and use cool or lukewarm water instead. Don't use a clarifying shampoo if your hair is severely damaged, as this could make the damage even worse. If you're unsure whether to use it or not, ask a stylist. Protein-based conditioners fill the tiny rips and tears in your hair, making it stronger. The repair is not permanent, and only lasts until the next time you wash your hair. The benefit is that your hair is stronger and more resistant to damage. Consider using a leave-in conditioner after you step out of the shower. This will help lock the moisture in and keep your hair hydrated throughout the day. Follow the directions carefully. Don't leave the conditioner in for longer than the recommended time, as this can make your hair brittle. Get your hair damp first, then apply a deep conditioner to it. Pull your hair up into a loose bun, and cover it with a shower cap. Wrap a hot towel around your head, wait 10 to 20 minutes, then rinse the deep conditioner out. Look for ingredients such as keratin, olive oil, protein, or shea butter. If you are in a hurry, apply a deep conditioner to your hair after you rinse the shampoo out. Leave it in for 3 to 5 minutes, then rinse it out. You can use hair masks once or twice each week. Heat some olive oil over the stove, then allow it to cool down to room temperature. Apply it to clean, towel-dried hair. Tuck your hair under a shower cap, then wrap a hot towel around your hair. Wait 1 hour, then rinse the oil out with cold water. Use shampoo to remove any residue, if desired. You can do this treatment 1 to 3 times a month. How much olive oil you use depends on how long and thick your hair is. You need enough to completely saturate your hair. For a deep conditioning treatment, leave the oil on overnight. How often you use a treatment depends on the product itself, so read the label carefully. In most cases, you can use them once or twice a week. If you don't see any progress after 3 months, your hair is likely damaged beyond repair. Visit a salon to have the damage cut out. Keep in mind that not all treatments work for everyone. What works for your best friend may not work for you. How short you cut your hair depends on how far up the damage extends. Ideally, you should cut all of the damage off. If your hair is damaged all the way to the roots and you don't want to cut all of your hair off, cut layers into it instead. This will prevent the damage from creeping further up the hair shaft. Make the most of your cut. Go for a chic bob or a cute pixie. If you want something more edgy, try an undercut instead. If you don't want to go too short, you can trim your hair every 4-6 weeks until the damage is gone. This will take longer, but will prevent the ends from fraying, which can increase the damage.
Summary:
Start your new hair care regime immediately. Use a clarifying shampoo if your hair is dry or staticky. Strengthen your hair with a protein-based conditioner. Turn a deep conditioner into a hydrating mask. Replenish your hair with a hot oil treatment. Give treatments 3 months before reassessing your hair. Cut the damage off as a last resort.
