Your eyebrows frame your face, so they're an important part of your look. If your brows are a bit too thin, they can distract people from admiring the rest of your features. Chemical hair-growth treatments help fill out sparse eyebrows, but you might feel reluctant to slather the stuff on your skin. Instead, try giving your brows volume with a few drops of castor oil. Castor oil's benefits come from ricinoleic acid, also known as omega-9 fatty acid. This acid works its magic by stimulating eyebrow growth and nourishing your hair follicles.
Wash your face and eyebrow area with warm water and cleanser. Pat your face dry with a towel.
Dip a cotton swab or thin-tipped makeup brush into a container of castor oil. Shake off any excess oil.
Brush a drop or two of oil on each eyebrow. Rub the oil in well with the brush or cotton swab.
Massage a drop of glycerin into each eyebrow, if desired. Glycerin may boost the effectiveness of this remedy.
Repeat this process nightly before you go to bed. You should see results within six weeks.
