In one sentence, describe what the following article is about: Do not use a plastic comb or a comb with no handle. Your hot comb must be made of metal or ceramic so that it won’t melt, and it needs a heat-resistant handle so that you don’t burn your hand. Hot combs can be purchased at beauty supply stores or online. If you have a gas stove, hold the comb so that the teeth are just barely getting brushed by the top of the flames. For an electric stove, hold the teeth against the hot burner, and use medium to medium-high heat. After 30 seconds, test the comb before you use it by setting it on a white paper towel. If the towel turns brown, your comb is too hot and will damage your hair. Let it cool for a minute and test it again before using it in your hair. This test is very important, as your hair can burn or fall off if the comb is too hot. Remove the clip holding one of the bottom back sections of your hair. Give that section a quick comb-through with a normal plastic-tooth comb before using the hot metal comb. This prevents getting the hot comb stuck in your hair. Position the teeth of the comb on the hair near your roots. Do not allow the comb to actually touch your scalp, but get it as close as possible so you can straighten any new growth. Holding the section of hair out from your head with one hand, use the other to gently pull the comb all the way from the root through the ends of the hair in one quick motion. Avoid keeping the hot iron comb in one spot for too long, or you could scald your hair. If one pass-through didn’t get it straight enough, you can go over it again with the hot comb. But don't do this more than one additional time, or you risk burning your hair. One pass should be enough for fine or medium hair. Two passes may be necessary for coarse or thick hair. After running the comb through your hair a few times, it will begin to lose its heat. Hold it over the flame or on the burner again, but remember that it's already slightly hot so it won't take as long to warm back up. Remember to test the comb on a white paper towel each time you heat it up to make sure it isn't too hot for your hair. Continue hot combing, working your way from the nape of your neck to the top of your head. Work from back to front since the back is the hardest spot to reach, and having the rest of your hair in clips will make it easier to see what you're doing.
Summary: Use a ceramic or metal comb with a heat-resistant handle. Hold the comb over a stove burner for 30 seconds. Test the comb on a white paper towel. Loosen a section of hair. Place the comb close to your scalp. Pull the comb down through your hair quickly. Repeat on the same section of hair if necessary. Reheat the comb periodically. Comb the rest of your hair.

In one sentence, describe what the following article is about: Typically calls are made with either one reed or two reeds and a wooden, acrylic, or polycarbonate sound chamber that amplifies the sound.   A single-reed call has a larger range, both in terms of volume and sound control, but is a little more difficult to master in terms of technique. This would be a good option for the advanced (or at least experienced) caller. Double reed calls are quieter but easier to control and easier to vary in terms of sound. A double reed will require more breath, but is generally a better option for the beginner. Making accurate sounds is more important than volume and double-reeds have a reliable "sweet spot" that sounds very realistic. While the notable differences are few between the different materials that make up the sound chamber, knowing the subtleties will provide you with a good guide if you're planning on buying and a smart use when you plan to use them.  Acrylic calls will make a loud, sharp noise. These are useful for open-water and long distances. They're also very easy to take care of, extremely durable, and will stay clean in the elements, but are the most expensive option by far. Wooden calls make a soft and mellow tone that some say is more accurate. They're inexpensive, but more difficult to take care of, though they will last for a long time if you do. Polycarbonate calls are generally the same price as wooden calls and offer a sound somewhere in between the sharpness of the acrylic call and the softer tone of the wood. They're water-resistant and reliable. If you're going to be hunting on open water, or it's particularly windy out, you're going to need a call with a lot of volume. If you're going to hunt from a blind, or with decoys the ducks come right up to, it would be better to have a softer call that offered more finesse in terms of sounds. When you know where you're going to hunt, you can pick a smart call for the job. Talk to local hunters and sporting goods dealers to check out available calls and learn about popular varieties. Detailed instruction guides are available to guide you through the process of carving a wooden duck call, fitting it with reeds, and tuning it to the proper specifications. This allows you the option of customizing your call and designing it creatively. Cheap do-it-yourself kits are also available, but these are often low quality.
Summary:
Choose between a single-reed or a double-reed call. Select between an acrylic, wooden, or polycarbonate call. Consider volume. Try  making a call.
