Losing strands is totally normal. But Dr. Wexler is quick to add that things like over-tweezing (it causes scarring to the follicles), waxing, severe weight-loss, stress, excessive touching, hormonal changes, and auto immune disease can cause irregular brow hair loss.
"As we age, it's completely normal for our hair, including eyebrows and lashes, to thin," says Audrianna Mora, the Global Education Manager of RevitaLash Cosmetics. Over time, skin loses its elasticity, causing hair follicles to become brittle and fall out.
Most of the time, eyebrows do grow back, but how fast they grow will depend on your age and overall health. A little patience, avoiding plucking and waxing, and changing your diet may be all you need.
Dermatologists believe that telogen effluvium, a condition where the body tells hair follicles to stop growing hair, is caused by hormones that the body produces in increased amounts as a reaction to anxiety.
Most people begin noticing hair loss during adulthood. But less commonly, some people start losing their hair as teenagers. Hair loss can be difficult for anybody, but especially if you're younger. Losing one's hair can have a huge impact on self-esteem.
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.
The average eyebrow has closer to 250 hairs. With a typical hair cycle (anagen phase of 60-70 days), that means we're looking at 3 hairs per day being lost for a normal cycle. If the patient's anagen phase is genetically determined to be a bit longer, we're looking at around 2 eyebrow hairs being lost per day.
When it comes to eyebrow regrowth, patience is key. “Give it at least two to three months to see hair growth. The hair growth cycle for eyebrows is between three and four months, so you need enough time for the hair to respond to your changes,” recommends Dr. Khetarpal.
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.
While hair on the scalp usually stays in the anagen phase for 2 to 7 years (depending on various genetic factors), the hair of your eyebrows and eyelashes stay in that phase for a meager 30 days. Therefore, they don't get as much time to grow and become as long as the hair on your head.
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.
Baldness or hair loss is usually something only adults need to worry about. But sometimes teens lose their hair, too — and it may be a sign that something's going on. Hair loss during adolescence can mean a person may be sick or just not eating right.
To sum up, if you have an X-linked baldness gene or your father is bald, the chances are that you will get bald. Moreover, if you have some of the other genes responsible for baldness, you are even more likely to lose your hair.
If your mom's dad is bald, then there's a high chance you'll go bald in the future. If your father is bald as well, then those chances go up even more! But even if baldness doesn't run in your mom's family, it's still possible you'll go bald.
Ideally, eyebrow slits take as much time to grow back as normal eyebrow hair. But, there are certain differences. If you use a razor, the hair will come back in a fortnight. However, if you tweeze the hair, they may take a lot more time to grow back, from weeks to months.
It only makes sense that skinny brows are making a comeback now. Much like the transition from the '80s to the '90s, the emerging beauty look is piggybacking off the big, bold eyebrow look spurred by celebrities like Lily Collins and Cara Delevingne in the 2010s.
