“While it depends on many factors, including the tweezers you use, how often you pluck and how traumatic it is for your hair, you won't be stuck with thin eyebrows forever,” says dermatologist Shilpi Khetarpal, MD. “Most of the time, they grow back.”
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.
If you're not partial to growth serums, Dr. Engelman recommends applying castor oil or olive oil on the brows to stimulate hair growth and the growth of strong hair follicles. She says castor oil is known to not only help thicken eyebrows but eyelashes as well. "[Meanwhile], olive oil can help strengthen the hairs.
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. An underlying medical condition can cause your eyebrows to fall out or prevent them from growing in properly.
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.
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.

Aging – Prostaglandin is the hormone that signals your eyebrows to grow. As we get older, our natural prostaglandin production declines. That's why it's common around menopause for our eyebrows to thin, grow a little longer, become coarse and even change color.
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."
"Don't over-pluck, and if you want shaping done, have it performed by a professional, keeping in mind that any severe damage done to the hairs may be irreversible. Eyebrow hair can grow back, provided there's not been too much damage to the hair cycle, or the follicular stem cells."
Vitamin E oil: Vitamin E oil is another excellent choice to promote eyebrow hair regrowth. Take a Vitamin E capsule and break it open to extract the oil from it. Apply this to your eyebrows and leave it on overnight for best results.
There are two main types of castor oil to choose from for eyebrow application: clear or cold-pressed castor oil and Jamaican black castor oil, which is pressed from roasted castor seeds. Both types contain the same properties that may help hair grow thicker. It's important to choose a product that is pure castor oil.
Olive oil is also good for your eyebrows, as it contains Vitamins A and E which helps your eyebrow hair grow faster and thicker and help keep it dark-hued. To Use: Massage your eyebrows with warm olive oil for 5 minutes before going to bed. Leave it on overnight, then rinse it off with warm water the next morning.
Coconut oil is a generally safe and inexpensive remedy that may help you grow fuller brows.

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.
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.
Makeup artist Cara Lovello agrees: “Castor oil is said to help with eyebrow hair regrowth. The vitamins in the castor oil nourishes the hair follicles.” Another one of its star components is ricinoleic acid, an ingredient that has been said to improve blood circulation.
Aging and hormonal issues may conspire to thin out your eyebrows. Board-certified dermatologist and RealSelf contributor Sejal Shah, M.D., a fellow of the American Academy of Dermatology, explains that simply the aging of hair follicles can lead to hair looking thinner and more sparse.
Once a hair has been removed from the root, a new one starts to grow in its place. While it does take time for the new hairs to be visible above the surface of the skin – the growth cycle of eyebrow hairs can take anywhere between four to six weeks – you can rest assured that they are indeed growing back.
