Ask your stylist to add layers with a mid-length cut to remove weight in the roots of your hair and give it some movement. Avoid too much layering because your hair may look like a triangle. Mid-length hair may look like a helmet when thick hair gets too big for a choppy bob. Ask your stylist to add dimension to a chin-length cut by adding layers. Get rid of fluffiness with a balm or silky wax. You need product to anchor your pouf and weigh down your hair while still allowing it to move.

Search online or provide pictures for your stylist to give a starting off point. Find inspiration from celebrities with the same hair type.
Summary: Tie a topknot to avoid bed head. Lose weight on heavy hair. Add layers to avoid helmet head. Cut your hair with proper thinning shears and razors. Braid your hair. Talk to your stylist.

In one sentence, describe what the following article is about: Your optometrist may give you a variety of tests as well as questions to determine if you may have cataracts. While some tests will be routine, other are more specific to detect cataracts. Your optometrist will ask you questions about your vision such as what symptoms you're having and how long you've experienced them. They will also perform a standard eye exam by using the eye chart and the viewing device to determine if you need corrective lenses. The test is called the slit-lamp examination. It lets your optometrist see the front of your eye under magnification to check for anything unusual. The slit refers to an intense line of light that your optometrist uses. Along with magnification, this helps your optometrist examine each section of the cornea, iris, and lens. If cataracts are visible at this test, your optometrist may perform additional tests or diagnose you at this time. In either case, they will need to know the severity of the cataracts for a full plan of treatment. This test dilates your pupils and makes it easier for your optometrist to examine the retina at the back of your eye. If you get this test, get a ride home, since it may be unsafe for you to drive. When you're given a pupil dilation test, special drops are placed in your eye to dilate the pupil. The doctor may use either an ophthalmoscope or slit lamp for this examination. Since the pupils are artificially dilated, your doctor will probably recommend sunglasses for your trip home to avoid excessive UV exposure to the eye. The tonometry test is also known as the pressure test. It lets your optometrist know if you have elevated pressure in your eyes, which can be dangerous and a sign of severe cataracts. Tonometry tests can be electronic, contact, or non-contact. The most familiar tonometry test is the eye puff test, in which a small puff of air flattens your cornea to check for increased eye pressure. The tonometry test also tests for glaucoma. Since many of the symptoms of cataracts can also be symptoms of glaucoma, it's a good idea to make sure this is not your problem instead of cataracts. If your optometrist thinks you may have cataracts, they may refer you to an ophthalmologist. An ophthalmologist will make the final diagnosis and determine a treatment plan. Your ophthalmologist may suggest corrective lenses if your cataracts are not severe; however, in many cases, cataracts are serious enough to require surgery. Surgery for cataracts is generally a routine, outpatient procedure. In this surgery, your ophthalmologist removes the cloudy lens and replaces it with an artificial lens. After the surgery, you'll want to have someone drive you home. Your vision may be blurry for a while after the surgery; however, if it's still blurry after a few hours or if you experience any pain, contact your ophthalmologist immediately.
Summary: Visit your optometrist to be screened. Use light and magnification to examine your eye. Perform a pupil dilation test. Get a tonometry test. Schedule an appointment with an ophthalmologist.

In one sentence, describe what the following article is about: The riser is the small pipe that connects the sprinkler to the water line. The sprinkler head sits on the riser, which helps to regulate its up-and-down movement, rather than directly on the water line itself. To remove the sprinkler head, twist it to the left, or counterclockwise. If the riser comes off with the sprinkler head, simply unscrew the two pieces and reattach the riser to the water line, being careful not to damage the threading of either piece in the process. Be careful not to let too much dirt or debris fall into the open water line. It may help to cover it with a small cloth or plastic bag while you're working. To ensure that you're getting the type of head you need, take the old part to the store with you and purchase the same brand and model. If for some reason that's not an option, confirm that the new head has the same overall length and diameter as the old one. Sprinkler heads come in several different sizes and lengths. If you get one that's too long, it will stick up high out of the grass after you install it. If it's too short, it may not reach the surface of your lawn from its seat on the water line. Consider shopping around for a head that features a removable flush cap rather than a traditional nozzle. Flush caps make it easy to clear dirt from the head following installation or use. Wind the tape neatly around the riser threads so that it forms a thin, uniform layer. Applying thread seal tape (also known as "Teflon tape") will fill excess space between the riser and the body of the sprinkler head, creating a snug connection and decreasing the chances of future leaks. You can find thread seal tape in the plumbing aisle of any hardware store or home improvement center. It's not necessary to use thread seal tape on polyethylene risers, as the soft plastic will typically bend and expand enough to form a secure seal on its own. Position the female end of the sprinkler head over the male end of the riser and twist it to the right (clockwise) to install it. Continue tightening the head by hand until it's nice and secure. Jiggle your new sprinkler head a few times to make sure it isn't loose. Any extra movement could be a sign of a poor connection. Rotate the sprinkler head until it's pointing toward your lawn, shrubs, of flower beds. The last thing you want is for your newly-installed sprinkler to water your car instead of your plants! There should be no need to adjust a radial sprinkler head. These send out water in a full 360-degree radius, ensuring even distribution over the area they're situated in.
Summary:
Unscrew the faulty sprinkler head from the riser. Buy a replacement sprinkler head that's the same size as the old one. Wrap a length of thread seal tape around the male end of the riser. Screw on the new sprinkler head. Adjust the sprinkler nozzle to direct the spray pattern where you want it.
