In one sentence, describe what the following article is about: Don't bleach hair that is freshly washed. The bleaching process will dry your hair out significantly, potentially causing damage and breakage. Your hair's natural oils will prevent this. A freshly-washed scalp is also much more sensitive and will itch more during bleaching. Your bleach kit will have two main components: dry powdered bleach and a hydrogen peroxide solution. Mix the two according to the ratios or instructions on your dye kit, using a tint brush or plastic spoon.  Follow the instructions on your kit if they are different from what is described here. Developers come in different strengths rated by numbered "volumes." If your hair is already fairly light, use volume 10. Volume 20 is for darker blondes, volume 30 for light browns, and volume 40 for darker browns and black.  Higher volumes can be more damaging to your hair, but they can also lighten it faster. If you've never bleached your hair to platinum blonde before, you will need to know how long it takes your hair to lighten. Select a small amount of hair close to the roots at an inconspicuous place and section it off. Brush on some bleach using a tiny brush. Let the bleach set and check the strand every 5 to 10 minutes. If your hair is not light enough after an hour, you will need to do multiple rounds of bleaching. Rinse the bleach away between rounds and reapply it. To minimize damage, do not leave bleach in your hair for over an hour. Use a tint brush to apply your bleach mixture evenly to your hair. Work in sections, brushing in the direction your hair grows.  Start from the very back of your head and work your way forward, leaving the sections of hair that frame your face for the end. If your hair is thick, flip up each section to expose the next layer of hair underneath and apply there, too. Leave about a one-inch section around your roots to do last, after the face-framing strands. The heat from your scalp will cause your roots to bleach a little faster than your normal hair. Try to go as quickly as possible to ensure an even color. Refer back to the results of your strand test to determine how long you should leave the bleach in your hair. Cover your hair up with either a shower cap or plastic wrap while you wait. Keep in mind that a little itchiness on your scalp is normal. Use warm water without shampoo. Be very careful to not get any bleach in your eyes as you rinse. If possible, ask someone to rinse your hair for you in a sink while you look up as if you were in a salon. If you aren't immediately moving on to the next step, allow your hair to air dry. Blow drying can further strip your hair of moisture, potentially exacerbating any damage the bleach has caused.
Summary: Wait a day or two after your last shampoo. Mix bleach powder with developer. Do a strand test. Apply the bleach. Let the bleach sit. Rinse out the bleach.

This will raise the alkalinity of the water by 10 ppm. Adjust the values to determine how much baking soda you need to add for the volume of your pool. For example, if you want to go from 60 ppm to 80 ppm in a 10,000 US gal (38,000 L) pool, you would add 2.5 pounds (1,100 g) of baking soda. Adding too much baking soda to the water at a time could raise the pH of the water. Let the baking soda settle and mix with the water before adding more. If you need to raise the alkalinity further, wait until the next day to add more baking soda. Use a circular motion as you pour the baking soda. It may cause some cloudiness in the water initially. The baking soda will sink to the bottom of the pool and settle before it begins mixing. To avoid cloudiness in the water, pour the baking soda directly into the skimmer. Your pool water needs to pump and circulate through a full cycle before you retest the water. Check the alkalinity using your test kit.  Let the pool run for a full pump cycle, which takes about 10 hours, before swimming. If your alkalinity levels are still off after the first baking soda treatment, add more baking soda to reach the desired ppm.

One-sentence summary -- Add 1.25 lb (570 g) of baking soda per 10,000 US gal (38,000 L) of water. Use only 2 pounds (910 g) of baking soda per day. Pour the baking soda into the deep end of the pool. Retest the water after 10 hours and make further adjustments if necessary.

Problem: Article: Plastic trash often kills birds in the wild, either because they eat it or they become tangled in it. By using less plastic, you can help reduce the dangers to birds in the wild. Simple changes you can make include using reusable cloth grocery bags instead of plastic, and switching to a reusable water bottle instead of drinking bottled water. When you do use plastic items, be sure to recycle them. Over time, this will decrease the amount of new plastic that needs to be produced. Millions of birds are killed by cars every year. Unfortunately, there’s no way to completely eliminate the danger posed by vehicles, but there are things you can do to help reduce the risk. When you’re driving the speed limit, you may be able to safely slow down or stop, giving the bird time to escape. If you speed, you might not have the reaction time needed to avoid hitting a bird that’s standing in the roadway or flying low to the ground. If you’re passionate about saving birds, choose a nonprofit conservation organization whose mission you feel passionate about, then donate to that charity. Private donations help these organizations continue to operate, so you’ll be doing your part to support their mission.  Some of the more well-known nonprofits working to protect birds include the National Audubon Society, the American Bird Conservancy, and Partners in Flight. You may be able to find regional organizations dedicated to protecting birds specific to your area. Local conservation efforts might include protecting nesting areas threatened by urban growth or tracking endangered bird species. Often, conservation programs will have opportunities for people to donate their time to helping protect birds. These might include spending time at a wildlife rehabilitation center or assisting with rescues after a disaster, like helping to clean birds after an oil spill. You can be alerted to volunteer opportunities by following different non-profit organizations on social media or signing up for their emails. If volunteering at a non-profit isn’t a good option, or if you’re looking for more ways to contribute on your own time, consider becoming a citizen scientist. Many conservation organizations rely on data like bird identification and population counts, and a lot of this information can be tracked simply by watching, classifying, and counting the birds that come to your feeder. You can then upload that information to the appropriate organization.  If you can’t be physically present to watch the birds, consider setting up a motion-activated game cam instead. For more information about becoming a citizen scientist, check out an organization like the Cornell Lab or Ornithology’s Project FeederWatch. You can learn more about Project FeederWatch at https://feederwatch.org/learn/. Some coffee and chocolate farms in Central and South America have started growing their plants in a forest-like environment, rather than clearing out the ground to grow them in full sun. This provides a safe environment for birds that would have been displaced by deforestation. You can help support their efforts by purchasing shade-grown coffee and chocolate whenever you see it.  The “shade-grown” designation will typically be clearly stated on the packaging. By maintaining a healthy ecosystem, including a natural habitat for birds, these farms are helping to increase the sustainability of their harvests.
Summary:
Switch to cloth grocery bags and reusable bottles. Drive the speed limit. Donate to an organization that works to conserve bird populations. Volunteer with a program to have a more hands-on impact. Become a citizen scientist by tracking bird data yourself. Buy shade-grown coffee and chocolate.
