Losing Your Eyebrows? 8 Reasons Your Brow May Be Thinner

Emily LaCroix

Hair loss can happen anywhere, even to your eyebrows. Yes, it can be totally frustrating when you first notice your thinning brows. It can leave you wondering how and why. Luckily for you, even if you suffer from thinning eyebrows, they don't have to stay that way! 

There are tons of ways you can help promote eyebrow hair growth. Here at TatBrow, we know how important having on-point eyebrows is, so we want to help you get to the bottom of your issue and help you get those bold brows back.  

Why Your Brows Are Thinning Out

There are tons of reasons why you may be experiencing hair loss. It can be something as minor as stress or something as flexible as an unbalanced diet. Sometimes, the reasoning is more complicated, like a preexisting skin condition or infection, but that's not to say those aren't treatable either.

Before we get into what you can do to get your brows back to normal, we think it's important to find the root of the issue. Let's talk about why your brows are thinning in the first place. 

1. Nutrient Deficiency

Your body relies on nutrients to function properly. You need to be consuming the right amounts of carbs, fats, and proteins. A very common reason people experience hair loss is due to a lack of proper nutrients. 

To aid hair growth, you need to ensure you're consuming all the right vitamins and minerals. If you aren't consuming enough vitamin A or Zinc, it can cause your cellular growth to slow down. Other deficiencies that can hinder hair growth are Biotin, Vitamin C (which helps collagen production), Iron, Vitamins E, B12, and D, And Omega-3 Fatty Acids. 

If you're experiencing hair loss, we suggest you evaluate your diet first. If you're sure you're eating all the right foods (and right amounts), then your hair loss may be due to a different reason. 

2. Eczema 

Eczema is a common skin disease that affects around 15 million Americans yearly. Eczema can be very uncomfortable and cause hair loss. If you experience itching, irritation, redness, and oozing of the skin, you may have eczema. 

While eczema isn't curable, there are tons of ways you can combat the symptoms. Of course, you will want to consult a medical professional before trying any treatments on your own. 

3. Stress and Anxiety 

Often stress or anxiety can cause hair loss. While sometimes it can seem hard to find a way to minimize stress or deal with anxiety, there are a few ways you can help manage them both. 

Try to put aside a day or two a week that you spend on yourself. Get a massage or get your nails done. Making sure you prioritize your mental health is essential to having peak physical health as well. 

You may not see changes immediately, but patience is key when dealing with hair loss and regrowth. Just try to stay positive. 

4. Pregnancy and Childbirth 

If you're experiencing hair loss during or after pregnancy, it's totally normal. Many women struggle with this symptom. It is a symptom that isn't talked about as frequently as nausea or morning sickness, but it is definitely very common. 

In most cases, after a few months postpartum, your hair loss should stop and begin to return to normal. 

5. Aging

It can be a hard pill to swallow, but aging is a big reason for hair loss. There's no shame in it. Your body does wonderful things every day, and hair loss due to age is just the way of life for most people. 

While you can't stop hair loss if it's caused by old age, you can always find ways to make your brows look fuller. 

Most young people fill in their brows for the aesthetic anyway, so you should never feel embarrassed if you're filling them in due to hair loss. 

If you're new to filling your brows in, we suggest getting a tool that makes the brows natural-looking. Our Microblade pen will leave your brows looking just as full and natural as they were ten years ago!

6. Over-Plucking or Waxing

Plucking, waxing, and threading causes trauma to your hair follicles, and after time it can cause them to stop growing. If you make sure you don't over-pluck your brows, then hairs not growing back shouldn't be an issue. The whole point of you plucking your eyebrows is because you don't want the hairs there anyways.

Be careful with how thin you're plucking your brows unless you want them that thin forever because they might not grow back!

7. Telogen Effluvium

Telogen Effluvium is a common reason for hair loss. Hair loss occurs after the hair growth cycle is interrupted by hormonal changes. Sometimes you can't always pinpoint what causes hormonal changes, but if you talk with your doctor, they may be able to help. 

It's a good idea to look at any medications you may be on. A common side effect of prescription medication is hair loss and drastic changes in hormones. 

8. Autoimmune Disease 

Certain autoimmune diseases can cause hair loss. One that is known to cause extreme hair loss is called Alopecia Areata

Alopecia Areata causes random spots of hair loss as well as complete baldness (in some cases). If you suffer from this autoimmune disease, then that might be why you're experiencing thinning of the eyebrows. 

How To Fix Thin Eyebrows 

Obviously, no one wants thin eyebrows. Suppose you're experiencing thinning of the brows. In that case, it can be super frustrating — especially if you've had big bushy brows your whole life. 

Yes, it can be upsetting, but luckily for you, there are so many ways you can help combat hair loss (especially in the brow department). 

Your first (and most popular) option would be to fill them in. Filling in your brows gives the illusion of naturally thick brows, even if you don't have 'em. 

Filling your brows in is great, and if you can find a good eyebrow pen that works for you, it's even better. However, it can be difficult for some people to get the hang of filling in their eyebrows. If you aren't gifted with a steady hand, we've got options for you too. 

Being able to do your brows perfectly is an art, so we get it if you'd like to skip that option completely. We recommend you try a brow enhancing or growth serum. They're known to help your brows grow thick, fast! 

There are also natural oils that are thought to help aid hair growth. Many people put Jojoba oil in their head hair to promote hair growth. If you apply Jojoba oil to your eyebrows, it will help you get those full brows back!

Of course, this can feel pointless if the eyebrow hair that grows just continues to fall out, but then maybe this isn't the option for you. Some people experience hair loss in phases, and after it grows back, it stays. 

If you don't want to fill in your brows or the growth serum isn't cutting it, you can talk with a doctor or dermatologist to see what they suggest!

In Conclusion

If you're suffering from thin or thinning eyebrows and don't know why we hope this helped you pinpoint the reasoning. It can be super frustrating when experiencing hair loss, but that's not to say it's hopeless. Sometimes all it takes is something as simple as switching up your diet or prioritizing your mental health. Stress and anxiety are very real causes of hair loss, and they should never be ignored.
