How to Grow Eyebrow Hair Back Fast: The Ultimate Guide

I can’t tell you how many times I’ve over plucked or misapplied wax to my brows, leaving myself with lopsided or pencil thin eyebrows. If this has happened to you, I can imagine the regret you are feeling right now!

Thankfully, there are several ways to speed up eyebrow hair growth and soon this will all be in the past!

So how to grow eyebrow hair back fast? The best way to grow eyebrow hair back quickly is to use an oil that stimulates hair growth or an eyebrow growth serum. Apply either the oil or serum daily for 8 to 16 weeks or until your eyebrow hair has grown back completely.

Read on to learn about the best oils to use and which eyebrow growth serum I recommend.

Castor Oil

Castor oil is typically used as a laxative, but this versatile oil is also packed full of proteins and fatty acids. There hasn’t been studies on castor oil for hair growth, but many natural beauty proponents swear by it’s hair stimulating effects.

Although there isn’t solid evidence on it’s effects, a study has confirmed that it increases the luster of hair which improves appearance. So it’s worth a try if you’re on a tight budget. You can find it at any grocery or drug store and it’s super cheap, at only a dollar or two per bottle. The downside is that it can irritate skin in some people.

To see if castor oil is okay for your skin, do a patch test by applying a drop in an area like the back of your hand. Rub it in and wait to see if irritation occurs. If after several hours, your skin is still fine, you should be good to go.

For brow growth, try rubbing a drop into brows and let it sit for 30 minutes. Then gently cleanse brows with your usual facial cleanser and rinse thoroughly.

Olive Oil

Olive oil is all natural and packed with vitamins A and E, which have been linked to hair growth. In some studies, olive products have specifically been linked to improved hair growth as well.

This oil is natural, inexpensive, and easy to find in any grocery store. Ideally, organic extra virgin olive oil is best. The main downsides? Olive oil can cause acne and it doesn’t smell great.

To use, just take a drop or two and gently massage into your brows up to several times a day. It may take up to 10-20 minutes of massaging for the oil to be thoroughly absorbed by your hair and skin. If too much oil remains on your eyebrows, gentle dot them with a towel to wipe excess oil off.

Coconut Oil

If the odor of olive oil is too much for you, coconut oil might be a better fit. It is full of fatty acids that improve texture and prevent breakage. It works by penetrating hair shafts so well that water is not easily absorbed. Wet hair is weak hair, so it is less likely to break after a coconut oil treatment.

Just like olive oil, you can use any coconut oil in the grocery store. However, my favorite coconut oil for skin and hair care is Fractionated Coconut Oil by Sky Organics because it’s less greasy and doesn’t go rancid as quickly.

Coconut oil can be applied to eyebrows the same way as olive oil: just massage a tiny amount into your brows up to several times a day.

Coconut oil is usually better for oily skin than olive oil and may be better for acne-prone skin as well.

Aloe Vera

There is no direct evidence that aloe vera improves hair growth. However, it does increase circulation when applied to the skin, which theoretically may help with hair growth.

The main advantage of trying aloe vera gel over the other oils listed is that it will be less likely to cause acne breakouts.

If you have an aloe vera plant, you can get gel by simply breaking a leaf in half and squeezing some gel out. Then store the leaf in the refrigerator. You can buy aloe vera leaves at some Indian grocery stores as well. Or you can buy aloe vera gel on Amazon.

To use for hair growth, just massage a drop into your brows once a day.

Eyebrow Growth Serum

Although oils are cheap and easy to find, eyebrow growth serums are simply amazing. They protect your eyebrows from breakage and stimulate growth, so your brows may be back in business as quickly as eight weeks.

The downside is the cost, typically ranging from $30-150 per container. If you can handle that price tag, it’s well worth it if you want better looking eyebrows quickly.

Although there are tons of eyebrow growth serums on the market, I recommend RevitaBrow Advanced Eyebrow Conditioner (click here to check out all the reviews on Amazon, many include before and after photos).

This serum is cruelty free, vegan, and hypoallergenic. It contains peptides and lipids that stimulate hair growth, strengthen hairs, and enhance shine and appearance. It also contains prostaglandin, which helps to darken light hairs, making brows look fuller and healthier.

Tips for Using Products to Grow Eyebrow Hair Back Fast

  • Avoid getting products or oils in your eyes. If you do, flush your eyes with water immediately.
  • Massaging the oils will work best if you use your fingers, but if you prefer, you can use a cotton swab instead.
  • If any product causes redness, irritation, or acne breakouts, stop using and try another one out.

What Hair Growth Products to Avoid

There are quite a few other suggestions on internet for how to grow eyebrow hair back fast or just speed up hair growth in general. I’ve looked into the claims behind many of these ideas and found that they either have no evidence or they have too many potential side effects to make them worth while. Here are a few I would pass on:

Petroleum Jelly

There is no evidence that it works for hair growth. This wouldn’t be so bad since it’s cheap, but it’s not a natural product and it causes acne in a lot of people. Therefore, I recommend skipping this.


There is one small study linking onion juice to hair growth. But until there is more peer reviewed studies proving that onion juice will make hair grow back more quickly, it’s definitely not worth smelling like an onion for weeks or months, in my humble opinion.


I’ve seen some websites that suggest putting turmeric on hair to stimulate growth. Ummm…do you want orange eyebrows? Because this is how you get orange eyebrows.

Egg Yolks

The hair growth benefits of eggs come from eating them, not applying them on your hair. Raw eggs can contain bacteria and are just gross, so I wouldn’t recommend putting them on your eyebrows.


There is no evidence that this speeds up hair growth. And squeezing lemons close to your eyes is a bad idea.

Other Ways to Boost Hair Growth

Reduce Stress

Stress wrecks havoc on the body and this affects hair growth as well. If you are under a lot of stress, take steps to manage it better. Some quick solutions may be as simple as getting some more rest and taking time to do yoga or mediation.

If stress is overwhelming, talking with a therapist or getting regular massage are great ways to take care of yourself (and the effects on your hair and health will be worth it).

Eat Well

Make sure you eat a well balanced diet, getting plenty of nutrients. Reduce sugar and processed foods. Some foods are especially good for hair growth, so try to include them in your diet each day:


Fish contain omega 3 fatty acids which have been linked to hair growth in some studies. To get the highest quality oil, eat wild caught fish. My favorite is wild caught Alaskan Salmon. It’s packed with healthy oil, but also low in mercury.


Eggs are packed with protein, zinc, selenium and other hair-stimulating nutrients including biotin. Your hair is made up of a protein called keratin. And biotin is the nutrient that is necessary for keratin production. So if you’re not getting enough biotin, your hair growth will be impacted.

Nuts and Seeds

Nuts and seeds are a tasty, easy way to get lots of high quality nutrition in your diet. They contain B vitamins, vitamin E, zinc and essential fatty acids. These are all necessary for healthy hair growth.

The best part is that you can pack them in your purse and keep them on hand for a quick, healthy snack, ensuring that you are getting some healthy nutrition each day without any prep work.


Most fruits contain antioxidants like Vitamin C. Antioxidants fight free radicals, those rogue molecules in your body that can damage hair follicles.

If you want the best bang for your buck, berries, including blueberries and strawberries, have more antioxidants than most other fruits.


Spinach is loaded with nutrients linked to hair growth, including vitamins A and C, iron, and folate. Get some in your day by adding it to a salad or sauteing a bunch in some olive oil for a side dish.

How Long Will This Take?

The hair growth cycle for eyebrows takes about four months total. But hair growth speed varies widely between people depending on a lot of factors, including genetics and age.

Some people can grow out brows as quickly as eight weeks, especially if they take extra steps to make the eyebrow hair grow back faster.

If your eyebrows seem to be taking forever to grow back or are thinner than they used to be, you may want to talk to your doctor to rule out any underlying health issues. Autoimmune disorders, anemia, thyroid disease are examples of medical conditions that can slow hair growth.

However, if you’ve over plucked your brows for years, some of those hairs may never grow back completely. The hair follicles can become damaged after plucking for years and eventually, they don’t produce new hair.

If this is the case, you may need to embrace thin eyebrows or try some tricks to make them look fuller.

How to Make Eyebrows Look Fuller

While you’re waiting for your eyebrows to grow back (or if you’ve given up on them), there are still a few things you can do to make your eyebrows look more appealing.

Make Up

You can tune up your brows pretty easily with just a brow pencil and some brow powder.

Start by brushing your brows, then use the brow pencil to draw a border around your brows, then color inside of the border.

Finish up by brushing brow power over the pencil marks, starting from the inner side of your brow near your nose and finishing on the other end of the brow.


If you want the full eyebrow look without using make up every day and have a big budget for just for eyebrows, microblading may be for you.

Microblading is a tattoo technique that leaves a semi permanent marks that mimic the look of eyebrow hair. Many women who have over-plucked their eyebrows for years have turned to microblading to make their eyebrows look fuller and have been happy with it.

The downside is the cost, ranging from about $350 to $800.

Final Takeaways

You have a lot of options for how to grow eyebrow hair back fast. Unfortunately, growing your eyebrows back completely may still take a few months, but you can get quicker results if you use hair stimulating products, eat well, and manage your stress better.

My fave eyebrow growth hack is using eyebrow growth serum, which tends to work well for most people and can give you good results within eight weeks.
