Make sure you are getting enough nutrients like vitamins A, C, D, and E by eating at least 5 servings of fresh fruits and vegetables daily. Include spinach and other leafy greens, carrots, tomatoes, and bell peppers. Get vitamin C from fruits like oranges, berries, and melons. Silica strengthens hair and is vital for hair growth. Bananas, raisins, oats, and beer are all rich in silica. Vitamin C helps the body absorb iron and produce collagen. Fruits like strawberries, blueberries, oranges, kiwi, broccoli, and a number of other fruits and vegetables are high in vitamin C. While you don't need to overeat protein, make sure you are getting enough in your diet. A balanced diet, including getting enough protein, can help reduce hair loss. Protein can also strengthen your hair and keep it healthier. Women 19-30 years old should be getting 5 1/2 ounces (or ounce equivalents) a day, while women 31 and older should be getting 5 ounces. Men 19-30 should be getting 6 1/2 ounces (or ounce equivalents) a day, while men 31-50 should be getting 6 ounces and men 51 and older should be getting 5 1/2 ounces. "Ounce equivalents" are servings of other proteins besides meat that the government considers equal to an ounce, such as 1 egg, 1/2 an ounce of nuts, and a 1/4 cup of beans or tofu. Stick with lean sources of protein, like fish, beans, and tofu, since high fat intake can increase testosterone, which has been connected with hair loss. Iron is one of the leading causes of hair loss, so making sure you get enough is important. Have your doctor check your iron levels, as you may need to take a supplement if you're not getting enough. Animal protein provides a good amount of iron, but so do leafy greens, lentils, and broccoli. The reason iron can cause hair loss is that your body may steal from your hair follicles if it is iron deficient. While omega-3 fatty acids won't necessarily prevent hair loss, especially if it's from a medical condition, they do contribute to healthier hair, and they are used by hair cells near the skin. Plus, they're good for your overall health. Eat fatty fish like salmon, trout, and herring. Vegetarians can get omega-3 from walnuts, pumpkin seeds, and avocados. B vitamins include riboflavin, folate, biotin, niacin, and others. These vitamins work together to help sustain healthy hair, which in turn can help prevent hair loss. You can take a supplement, but you can also get many of these vitamins from your diet. Leafy greens, vegetables from the ocean, and whole grains are all good sources of B vitamins. Sulfur, particularly that found in the amino acid L-Methionine, can increase hair health. Nuts, especially Brazil nuts, are high in this amino acid, as well as animal protein, soy beans, and sesame seeds. Vegetables like leafy greens also provide this amino acid. Not getting enough biotin in your diet can make your hair straw-like and brittle. When your hair is brittle, it's more likely to break, leading to you losing hair. Increasing biotin in your diet can help with hair loss. Eggs yolks, whole grains, yeast, soy flour, and liver all have high levels of biotin. Being hydrated is necessary for good health, including healthy hair. Make sure you are drinking the recommended amount of water. The Institute of Medicine recommends that men consume 13 cups of water daily and women consume 9 cups of water daily. Try drinking water with fresh fruit like strawberries or oranges in it for added flavor. If you are having trouble getting your necessary nutrients from diet alone, you may want to add a supplement that is specifically designed for reducing hair loss and contains all of these important vitamins and minerals. You may also consider taking a supplement with 500 to 1,000 milligrams of L-Lysine daily, which can help improve hair loss. Many eyebrow growth products are currently on the market, including gels and serums. None have been approved by the FDA for treating eyebrow loss. Use any such products with caution and monitor closely for side effects. If you're diabetic, having uncontrolled blood sugars over a long period of time can lead to hair loss. Therefore, to decrease this problem, try to keep your blood sugars under control through eating the prescribed diet for diabetics, taking your medications, and monitoring your blood sugars. If your blood sugars are often out of control, talk to your doctor about changing up your medication.

Summary: Eat plenty of fresh produce. Eat more lean meats and legumes. Get enough iron. Eat omega-3 fatty acids. Get plenty of B vitamins. Check your sulfur intake. Get enough biotin. Drink enough water every day. Consider taking a hair growth supplement. Maintain a consistent blood sugar.

Most conductive glasses are coated with an indium tin oxide residue. This allows the surface of the glass to conduct electricity rather than insulate it. You can buy conductive glass online or at a solar supply store. This glass is usually found in 1x1in (2.54x2.54 cm) squares. Add ethanol to your titanium dioxide in a glass beaker and stir. You should use the most pure ethanol you can find. Two hundred proof lab grade ethanol is best, but vodka or Everclear will work in a pinch. Use about one milliliter of ethanol per donut and shake or stir the solution in a glass or beaker. Put a layer of tape around three sides of the glass. This will help you control the depth of your coating. Use a dropper or pipet to drop a small amount of the titanium dioxide solution onto the surface of the glass. Use a microscope slide to scrape the the excess liquid off, leaving just a thin coating. Repeat this process ten times. Each drop should be sufficient to coat the glass one time with a thin film. In total, you will use ten drops to form ten layers of titanium dioxide. Put the solar cell into a clear, heatproof beaker or dish. Place the container on a hotplate (or place the solar cell directly on the hotplate). Turn the hotplate on and cook the cell for 10-20 minutes. You will have to watch the cell closely. It will turn brown, and then back to white. When the cell goes back to its original white color, this means that the organic solvents (the ethanol) have burned off, and the cell is finished heating. Teas contain organic compounds known as anthocyanins. These compounds are good at capturing light in the visible spectrum. Brew a cup of herbal tea and submerge the solar cell for a few hours. Darker teas, such as hibiscus, work best. This will stain the cell and allow anthocyanins to bind to the surface of the cell. The cell is now capable of capturing visible light. Prior to staining, the cell could only capture light in the UV spectrum.
Summary: Use conductive glass. Make a titanium dioxide solution. Coat the glass. Cook the solar cell. Stain the cells with tea.
