What is a one-sentence summary of the following article?
Your hair follicles need vitamins, nutrients, and proteins to function properly and build strong hairs. These are delivered through the blood stream, and massaging your eyebrows can stimulate circulation, ensuring your cells get the nourishment they need. Gently massage your eyebrows using the tips of your fingers. Make circular motions along the length of your brow bone. Your blood system delivers nutrients to the cells in your hair follicles, but it's up to you to provide your body with those nutrients. A healthy, balanced diet will keep your hair strong, glossy, and can prevent some types of hair loss.  Eat proteins like nuts, chicken, turkey Greek yogurt, and eggs to prevent hair growth from stalling or entering a resting state. Your hair is made from proteins, and can't produce new hair if you aren't providing your body with enough protein.  The B vitamin biotin can be found in eggs, almonds, wheat bran, salmon, and avocados. Biotin enhances hair growth and can also make hair grow faster.  Dark greens like spinach, kale, and chard contain vitamins A and C. Vitamin deficiencies can cause your hair to fall out. If you're feeling impatient, you can use makeup to make your brows look fuller or fill in any bald patches. Use a sharp eyebrow pencil and draw "hairs" with light, feathered strokes. Concentrate on holes and sparse areas. Follow this up with a dusting of brow powder, which clings to your existing hair, and your eyebrows will look fuller.  Never stray too far from your natural eyebrow color. If you are a brunette or a redhead, look for a pencil that is one shade lighter than your hair.  If you are a blonde, look for a pencil that is one shade darker than your hair color.

Summary:
Massage your eyebrows to improve circulation. Eat a protein and vitamin-rich diet to help your hair grow. Fake it by using an eyebrow pencil and powder.
