Your brows can begin to look thin and sparse if you have over-tweezed or waxed them, or simply because they've grown that way for years. If your brows look thin and sparse, you can grow them out to look bushy and full. It may take some time, as long as six months, to grow them out and achieve a thicker look. In the meantime, Anastasia Soare, an aesthetician featured in the "Los Angeles Times", suggests that you use a waxy eyebrow pencil to make your eyebrows look fuller and thicker.
Eat a well-balanced diet. For hair to grow anywhere on the body, you need to be following a healthy diet high in the essential nutrients required for the body to grow hair, such as the B vitamins, beta carotene, iron and protein. Some good foods to add to your diet are fish, poultry, milk, whole grain breads, whole grain cereals, beans, carrots, peppers and green leafy vegetables.
Take a daily supplement. If you are worried you are not getting the right vitamins and minerals from food, consume a supplement specially formulated for nail, skin and hair health.
Grow one row at a time. Soare reported to the "Los Angeles Times" that women should grow one row of hair at a time, starting with the one closest to your eyebrow.
Apply an eyebrow growth stimulating product. Topical treatments may encourage faster regrowth of your eyebrow hair. The solution is applied topically to the brow area every night after cleansing the face.
Use a highlighter stick or powder to improve your appearance while you grow in your thicker eyebrow hair. Put a small amount over stubble as the eyebrow hair grows back. Blend it with the rest of the brow for a more natural look.
Trim back brow hair from time to time. If the hair starts to get too bushy, you should trim it back with a pair of nail scissors.
