Fix Thin Eyebrows: 5 Proven Ways to Achieve Gorgeous Brows

If the cause is a medical condition, a brow pencil can create a more uniform look.

According to Washington, D.C. dermatologist Elizabeth Tanzi, MD, if your eyebrow hair is falling out, it may be a symptom of an underlying disorder. “Thinning brows can be a sign of a condition like eczema, alopecia or an underactive thyroid, all of which can cause you to lose your hair.”

An easy way to transform thin, out-of-shape brows is with a brow pencil, like KIMIKO Beauty Super Fine Eyebrow Pencil Automatique ($31) which has fine point tip to help smoothly and easily draw on hairs to shape, define and fill in sparse areas.

If the cause is overplucking, revive sparse areas with a brow serum.

Overplucking is a common grooming mistake, but it’s also one of the biggest reasons for hair loss in the eyebrows. “Eventually, the plucked hair grows back in, but after a while, the growth rate shortens a bit with each cycle,” says New York hair restoration surgeon Carols Wesley, MD. “The areas that have been overplucked come back shorter and thinner, leading to long-term thinning.”

Try a strengthening brow growth serum like Anastasia Beverly Hills Brow Genius ($65), which contains peptides, biotin and castor oil to help keep brow hairs softer and fuller. 

If the cause is a poor diet, thicken existing hairs with a tinted brow wax.

A diet lacking in vitamins A, B, D or E, or an iron deficiency, can be the culprit for your sparse eyebrows. In addition to adopting a well-balanced diet, a key step to getting fuller brows is to thicken or darken the individual hairs.

For a quick fix, fake better brows in an instant with Lawless Hold Up Soft Set Creamy Brow Wax ($21), which tints, shapes and sets natural hair to mimic the look of better brows. 

If the cause is age-related, try microblading for a long-lasting fix.

As you age, you may notice a change in the density of your brows. Although the hairs may still be growing, they may appear thin and faded in color. A technique called microblading uses fine, hair-like strokes to deposit semipermanent pigment into the skin. “Microblading is the most natural-looking way to make your eyebrows look like they have more hair,” says brow expert Nadia Afanaseva of Eye Design New York. “You can create any shape or arch you want, and your new brows can last anywhere from one to three years.”

If the cause is genetic, eyebrow restoration can boost hair growth.

Hereditary hair loss can shorten the time that hair spends growing, causing the follicles to shrink. An eyebrow transplant permanently restores growing hair by using healthy follicles from a donor site on your scalp and transplanting them to an area where brow hair is weak. “On this patient, I removed hair from the scalp and placed individual hairs into incisions made in the brow,” says Philadelphia hair restoration specialist Thomas Griffin, MD. “Once the grafts heal, it grows like normal hair.”
