Problem: Article: It's important to start off with a clear base coat applied thinly, smoothly, and carefully. Some base coats act as adhesives that help to retain the nail color and make it last longer, preventing chipping. Others are nail thickeners, which brittle nails sorely need. Talk to your friend which is more up their alley? Just one layer is plenty. Base coats also don't take that long to dry, so don't feel the need to take a break. By the time you hit the tenth nail, the first nail should be ready for color. Ask your friend which color they would like and begin applying two coats evenly on each nail. Make the layers thin thin layers look better than one gloopy one. Start on the same finger as you did with the base coat and work your way over. Take your time, applying evenly and thoroughly. One swipe down the center, and one on the left and right for each finger. If you wind up getting color on the skin, take a small cotton swab dipped in nail polish remover and very carefully wipe it off, not touching the nail. Alternatively, take your own nail to lightly scrape off the not-yet-dried nail polish as soon as it hits the wrong place. Has your friend requested a French manicure? You can read about it here. The wide world of nail polish is getting wider and wider. If you have gems, tape, and other nail art equipment, why not try it out on your friend? You could also take a toothpick and make fancy designs. After all, the only way to improve is to practice. If your friend isn't sure if they want nail art, suggest just doing it on one finger. They can try it out, and the one-finger look is actually super trendy if they wish to keep it that way. Need ideas? Try reading wikiHow's article on how to do nail art. To seal in the color and prevent chipping, add on a topcoat. This also makes it super shiny and eye-catching. Keep this layer thin, however; another gloopy layer shiny though it may be won't make the nails look any better. Your friend should reapply a topcoat every day or so if they want the color to last longer.
Summary: Apply a base coat. Pick a polish. Apply nail art if requested. Apply a topcoat.

Problem: Article: Lemon juice is full of citric acids, which have a bleaching effect when they are repeatedly applied to hair. You will most likely need to repeat this process several times to see a significant change in your hair color.

You may also use limes, grapefruit, or any other fruit that contains a high concentration of citric acid. To make your own: Buy or pick four lemons. Slice the lemons in half. Squeeze the lemon juice into a bowl, or use a juicing device. Lemon juice is very acidic. Consider mixing 1/4 cup of water into every cup of lemon juice to avoid damaging your hair. If you use shampoo, make sure that it is thoroughly lathered into your hair. Make sure to mix it deeply into the roots. Be sure to shut your eyes tightly to keep out the lemon juice. The citric acid will burn if it makes contact with your eyes. It is important that you give the citric acid time to leach into your hair, but you do not want to leave the mixture in for too long--prolonged exposure to citric acid can damage your hair. The citric acid in lemon juice tends to have a drying effect on hair, and you do not want to risk damaging your locks.
