4 months is the exact answer.
Eyebrows can fall out for a variety of causes. Excessive plucking, shaving for years, and even shaving are all major causes of sparse or absent brows.
There are other physiological reasons for brow hair loss, such as alopecia areata, hormone imbalance, and poor nutrition.
Another well-known chemo adverse effect is brow hair loss. The cause of your brow loss, your age, and other factors may influence how long it takes for your hair to come back. According to research, brows usually recover after four months.
Do your brows regrow?
It was thought that if one’s brows were shaved or lost, they would never grow back.
However, your brows should regrow unless you have a medical problem causing your hair loss.
A 1999 research dispelled the notion by demonstrating that shaved brows come back naturally. In the study, five patients had one of their brows shaved, while the other brow was kept intact for comparison.
Photographs obtained at each follow-up were used to measure regrowth over six months. Except for one female participant who had light-colored, sparse brows that took a full six months to grow back to normal, all of the other participants’ brows had grown back to normal after four months.
Hair growth follows a three-phase cycle. The phases are not coordinated, and some hairs remain in one phase for a longer period than others.
Phases of the brow growth cycle
Hair growth occurs in three stages. Anagen, catagen, and telogen.
- Anagen is the first and most vigorous developing phase; brows grow at a slower rate of 0.14mm to 0.16mm per day during this phase. This stage lasts between 30 and 45 days.
- Catagen is the intermediate phase of the cycle, lasting 2 to 3 weeks, during which growth ceases, and follicles come closer to the skin and begin to fade.
- Telogen, or the resting phase, is the final stage of the growth cycle in which new ones replace older hairs. For example, when brows develop, older hair falls off, and new hair grows to restart the cycle. This stage lasts between 4 and 8 weeks.
The length of the anagen phase determines hair length. Eyebrow hair grows at a slower rate than scalp hair and has a significantly shorter anagen phase. Eyebrows grow at a rate of 0.14 mm to 0.16 mm every day.

Do brows regrow after shaving?
Although it is not a systematic method for shaping your brows, you may have tried it if the notion of plucking is too uncomfortable.
While we don’t advocate shaving your brows owing to the risk of cutting yourself or worse, plus it’s simply too difficult to obtain a precise shape, the good news is that if you have already shaved them, your hairs will come back rather rapidly.
Because shaving eliminates hairs above the skin’s surface rather than from the root, hairs will regrow within a week or two.
You’ll probably discover that they grow back so fast that you’ll need to reach for your razor to keep your brows clean constantly. Even more, motivation to try a different approach!
Do brows regrow after plucking?
When a hair is pulled from the root, a new one grows in its place. While it may take some time for new hairs to appear above the skin’s surface — the development cycle of brow hairs can take anywhere from four to six weeks – you can be confident that they are coming back.
Hairs may not return if a follicle has been injured or traumatized during the hair removal process. When this happens, repetitive and excessive tweezing is to a fault.
Do brows regrow after waxing?
Hairs will grow back slower since each hair has been plucked from the root, just like plucking. Some people might anticipate their hair to come back softer and sparser after waxing, while others will notice that their hair grows back just as consistently as it did before waxing.
Do brows grow back after being threaded?
Threading, which has been the predominant method of hair removal in Asia for generations, involves rolling twisted cotton thread pieces over your brows to pull them out of the follicle. Threading (like plucking and waxing) removes hair from the root. Thus it will take many weeks or more for your hair to return.
Do brows regrow after microblading?
Microblading (also known as feathering) is a brow tattooing method that employs a fine blade to mimic individual hairs in sparse brows. It does not affect normal hair development because it does not remove hairs but rather creates ‘fake’ hairs where none exist naturally.
Why Does It Take So Long to Regain Your Eyebrows?
A variety of things might impact how soon your brows grow back. Here are a few examples:
- Cuts, burns, and other brow hair follicles
- damage caused by tweezing and waxing
- Pregnancy
- Anxiety and Stress
- Aging-related thyroid illness
- Skin disorders such as eczema and psoriasis are examples.
- Abrasive makeup
According to the American Cancer Society, chemotherapy medications destroy hair follicles, resulting in hair loss. Chemotherapy targets and destroys all rapidly dividing cells in the body, including those responsible for hair growth.
Chemotherapy does not always result in hair loss. Which hair falls out and how much hair falls out varies from person to person — even while using identical drugs. Some drugs induce hair loss all over the body, including the brows, while others cause scalp hair loss.
Chemotherapy hair loss is often temporary. Brows and other hairs frequently begin to sprout before therapy is done.
Your brows will regrow almost always, but your age and overall health will dictate the rate at which they will regrow. A little effort, avoiding plucking and waxing, and a diet adjustment may be all necessary.
A medical problem causes your brows to fall out or prevents them from growing correctly. Consult a doctor if your brow hairs fall out and stagnate for no obvious cause.
How to Regain Eyebrow Growth
Here is a few brow routines to make your face more brow “friendly”:
1. Get rid of that magnifying glass.
Give your brows the space and time they require, just like you would a broken relationship. “However, if you gaze in the magnifying mirror every day, worrying over each hair, your brows will never have a chance to recuperate,” Dr. Khetarpal advises.
2. Castor oil
Castor oil has long been used as a natural home cure for hair loss and has recently been popular for brows and eyelashes.
There haven’t been any scientific studies to verify that castor oil may restore hair, but the major ingredient in it, ricinoleic acid, has been related to hair regeneration. At the very least, it can keep your brows moisturized, which may help avoid breakage.
3. Fresh out of the shower, pluck your brows
After a shower, skin becomes softer and more sensitive. As a result, Brow hairs easily slip out with minimum effort.
4. Keep a close eye on your nutrition.
Eating a well-balanced diet helps boost brow development. If you aren’t receiving enough nutrients from your diet, consider taking a supplement. Of course, before beginning a new supplement program, consult with your doctor.
Iron
Anemia caused by iron deficiency is a common cause of hair loss that can also affect the brows. Getting enough iron in your diet may aid in the growth of your brows. Iron-rich foods such as iron-fortified cereals, white beans, and spinach can help you get more iron.
Biotin
Biotin, often known as vitamin H, is a member of the vitamin B family. Biotin tablets for hair growth are becoming increasingly popular. Although research on biotin for hair development is sparse, some indication is that increasing biotin consumption may improve hair growth.
You may enhance your biotin intake by eating biotin-rich foods, including organ meats, nuts, and whole grains. Biotin supplements are also available on the market.
Ingredients derived from nature
By stimulating follicles, vitamin E, olive oil, coconut oil, lipids, and biotin products help eyebrows grow faster and thicker. These natural substances also hydrate the hair follicle. Some individuals also use henna eyebrows 1 technique for brow tinting, which is a natural substance for the brow tinting.
5. Aloe Vera gel
Calcium and magnesium are both found in Aloe Vera leaves. Calcium is an important component for hair health, while magnesium helps to promote follicular hair development.
6. Experiment with a brow growth serum or other topical treatment.
Bimatoprost (Latisse®) is a prescription ointment used to lengthen and thicken eyelashes. It has been demonstrated to benefit brows.
Consider 2% or 5% minoxidil (brand name Rogaine®) if you prefer an over-the-counter option. While it is intended to stimulate hair development on the scalp, it can also stimulate hair growth on thin brows.
There are two warnings about using Rogaine:
- Feel the burn: If you get it in your eyes, it may create a burning feeling.
- Unwanted hair: Rogaine has a field effect, which means that even if you only use it on your brows, hair will grow elsewhere on your face.
Conclusion
There is no fast remedy for brow thickening. Your age, genetics, and hormones affect the rate at which your brows grow back. Eating a nutritious, well-balanced diet may be advantageous. Hair is mostly made up of proteins, and animal studies have shown that a shortage of protein can result in hair loss.
B vitamins, as well as vitamins A, B, C, and D, have also been related to improved hair growth. These vitamin supplements are abundant in dark green vegetables such as kale and spinach.
Treatment depends on the source of your hair loss; you may need to see a doctor to treat any underlying ailment causing your brow loss.
