In one sentence, describe what the following article is about: Do you wash your hair every single day? This can really dry it out, since you're washing away the oils your scalp produces to keep your hair shiny and healthy. Washing every day can also lead to oily hair, since stripping your hair of its oils causes your oil glands to go into overdrive. Try this routine instead: Wash your hair just two or three times a week. If you feel like your hair is getting dirty between washes, you can apply a dry shampoo on the days that you don't wash your hair. Just apply a small amount to your roots and then rub it throughout your hair to the ends. Rinse out your conditioner with cold water. Hot water is hard on your hair and can lead to split ends and frizz. Rinsing out your conditioner with cold water seals the cuticle, resulting in shiny, bouncy hair. Think of your hair like your best silk dress. After hand washing it, would you ball it up and wring it out? No, that would destroy its shape and fibers. Your hair is similarly fragile and needs to be treated with care to stay healthy. After washing your hair, gently pat it dry with a towel instead of wringing it out. Let it finish air drying. Use a comb instead of a brush. Forcing a brush through tangled hair can cause it to rip and break. Use a wide-toothed comb to gently work through the tangles from bottom to top to prevent breakage. Put away your hair dryer, straightener, curling iron, and hot rollers unless you have a special occasion at hand. Applying heat to your hair can damage it, so it's best to let your hair air dry instead. If you want to use the blow dryer sometimes, use it on a cool setting. When you do use heat styling devices, be sure to put a protective serum in your hair beforehand. Try an egg yolk and olive mask, a vinegar rinse, or put plain yogurt or sour cream on your locks. Search online for instructions. Egg oil contains Omega-3 fatty acids, antioxidants, and cholesterol, and is like a complete solution to hair problems like hair loss, grey hair, and frizzy hair.
Summary: Change your washing routine. Handle your hair gently. Use heat styling devices sparingly. Use homemade treatments. Use egg oil (Eyova):

A human foot has an arch underneath, which helps propel the body forward each step, as it acts like a spring. Animals like apes have flat feet, as they grasp the ground with their toes. The arch is kept in place by ligaments. Also, the big toe on an ape faces outward, perpendicular from the other toes. In a human, all of the toes go in the same direction. In addition, humans bear weight on the whole foot, which is why it is long and narrow. Other animals mainly bear weight on their toes. Other animals walk on all fours, which is why they tend to have larger bones in their arms than humans. Humans don't bear weight on their arms, so the bones don't have to be as large. For instance, an ape or even a horse bears weight on all 4 legs, so the upper limbs are more developed. Because humans walk upright, the thigh bone, otherwise known as the femur, is the longest, strongest bone in the body. On the other hand, the femur will be the same length as other bones in animals. Look for the long bone starting just above the knee and extending up towards the pelvis. The 2 calf bones, the tibia and fibula, are separate in humans. In other animals, these 2 bones are often fused together. Check these bones, and see if they are a single bone or 2 bones to identify animal or human remains.
