Much like the hair on your head, eyebrows can thin out or just stop growing.
In fact, all hair prevents growing after a certain length! Leg hair, arm hair, eyelashes, eyebrows, head hair, and even the hair on your butt will stop growing after a specific period of time. Precisely how long your hair can grow relies most importantly on your genes, age, hormones, and common health.
There may be a reason your eyebrow hairs aren't growing back. If you over-plucked too often or too hard, you could trigger your eyebrow to react to the plucking as trauma. Trauma to the follicle will mean your eyebrows won't grow back–at least not for now, because they're resting.
Hair at your eyebrows, like hair on other parts of your body, goes through a regular growth cycle," says New York City-based dermatologist Joshua Zeichner. "Eyebrow hair grows actively for three to four months, followed by a resting phase, after which the hairs are released from the skin.
As the follicles grow more sensitive to androgens, the hormones keep them in the anagen phase longer, leading to more hair growth with age in places such as the eyebrows, nose and ears.
It was an unexpected finding as previous research showed that thicker eyebrows are seen as more masculine and dominant. 'It could be that relatively thicker eyebrows signal other qualities, such as a tendency towards more grooming. 'It is also possible that this preference reflects current fashion trends.
Thick Eyebrows

So, don't expect to see those missing hairs pop up instantly a few days after plucking. Yates notes that "eyebrows have a three- to four-month growth cycle, so you need to wait at least two to three months to see if they will regrow after you stop plucking them."
Unfortunately, there's little to no evidence that any of the ingredients in Vaseline, which is a brand name for petroleum jelly, can grow thicker or fuller eyebrows. However, Vaseline is very moisturizing and may actually help eyebrows look fuller and thick, even if they're actually growing at the same rate.
Normal aging processes
As people get older, they may notice hair thinning or loss affecting the head, eyebrows, eyelashes, and elsewhere. Over time, some hair follicles stop producing hair, and the hair shafts become finer.
"Just like all hair, it's normal to lose a few eyebrow hairs daily," says Dr. Wexler. "The hair on our body and brows goes through a growing process which, in fact, is the replacement of the old hair with the new grown hair," adds Kety Vladuca, Eyebrow Specialist at Julien Farel Restore Salon & Spa.
For the Mexican American cholas of the 90s, their iconic makeup style -- featuring, you guessed it, dark pencilled thin brows -- came to represent their feminine power in the face of a hostile society.
Scientists have established that the shape, color, and thickness of your eyebrows are inherited traits. In one major study in 2015 , scientists found a strong relationship between inheritance of specific genes and eyebrow appearance.
The Reason: Aging Skin
Over time, skin loses its elasticity, causing hair follicles to become brittle and fall out. Some of these follicles may stop producing hair altogether, which is when eyebrows begin to recede and appear patchy.
Eyelash and eyebrow hair is the slowest growing hair on your face, compared to beard or scalp hair. Eyelash and eyebrow hairs can be expected to grow about 0.16mm per day, or about half as fast as your scalp hair.
For a healthy adult, a tweezed eyebrow hair will grow back in an average of 64 days. On the other hand, if you've been tweezing the same area for a long time, it may be too late. Eyebrow hair follicles are very sensitive to injury, and repeated plucking can permanently damage the hair root.
Eyebrow restoration
You can talk with a dermatologist or cosmetic surgeon about hair grafts that target your eyebrows. These types of grafts use your existing hair follicles to fill in thin spots and encourage regrowth.
If your brows are mostly gray, dyeing them is the best fix. Ask your stylist if your salon offers the service (it's often free when you get your hair colored), or have it done at a spa. "Even if the hair on your head is silver or gray hair, I suggest dyeing brows light brown," says Petrescu.
Conclusion: Tweezing does not cause hair to grow back thicker. Changes in hair texture are likely caused by hormonal and genetic factors.
Castor oil: Castor oil has an essential composition of a chemical, which is useful for hair growth. Gently apply and massage castor oil on each eyebrow for two or three minutes. Leave this on for 30 minutes. Then wash your eyebrows with lukewarm water and a gentle cleanser.
The eyebrows that are high in height and relatively obvious in turning can enlarge the distance between the eyebrows and the mandible, so the round face is suitable for drawing eyebrows with high bending. This combination of face and eyebrows will make face increasingly attractive.
I am reading a book called Survival of the Prettiest by Nancy Etcoff in which she says studies have shown that a higher brow actually looks less attractive to subjects who viewed various individuals with different brow heights. A low brow was considered sexier, more alluring, and more attractive.
In a study of 1,000 participants done at Oakland University in Michigan, researchers found that thicker brows on women were considered more attractive than thinner eyebrows.
