You can also get an eyebrow transplant, which grafts hair with follicles from above the ears to the brow area to encourage new hair growth. If it takes, the outcome lasts forever.
One step further is tattooed eyebrows, which are meticulously made into a perfectly arched eyebrow shape with textured, hair-like strokes that can last a lifetime.
If you aren't fond of being poked and prodded, the market's best brow tints, brow gels, and concealers will work wonders to spruce up your disappearing eyebrows.
