If you’ve noticed your cat’s eyebrows looking a bit sparse lately, you may be wondering – do cat eyebrows grow back? Eyebrow hair loss in cats can occur for various reasons and may have you concerned about their health or appearance.

If you’re short on time, here’s a quick answer to your question: Yes, cat eyebrows often grow back on their own over time as long as there is no underlying medical condition causing permanent hair loss.

In this comprehensive article, we’ll explore the structure of cat eyebrows, reasons for eyebrow hair loss in cats, whether cat eyebrows grow back after shaving or plucking, steps you can take to encourage regrowth, and when to see your veterinarian about eyebrow hair loss.

The Structure and Purpose of Cat Eyebrows

Anatomy and Location of Cat Eyebrows

Cat eyebrows, also known as supraorbital ridges, are located above the eyes on a cat’s forehead. They are formed by the zygomatic and frontal bones of the skull. The eyebrows consist of hair follicles and sebaceous glands that produce oils to keep the hairs conditioned.

The main structural purpose of cat eyebrows is to protect the eyes by shielding them from dust, debris, sweat and moisture. The ridges of bone under the eyebrows act as a barrier to keep foreign particles from getting into the eyes. The eyebrows also help shade the eyes from bright sunlight.

Sensory Functions of Cat Eyebrows

In addition to providing protection, cat eyebrows serve some important sensory functions:

  • The eyebrows contain sensory nerve endings that can detect touch and movement. Light brushing against the eyebrows stimulates these nerves.
  • There are scent glands associated with the hair follicles of the eyebrows. Cats use these to deposit facial pheromones, which are chemical scent signals that communicate information to other cats.
  • The eyebrows help funnel scents upwards to the nose so cats can better detect odors in their surroundings. The angle of the eyebrows toward the nose likely enhances this olfactory function.
  • Thicker eyebrows seen in some cat breeds, like the Persian, may also help amplify sounds toward the ears.

Common Causes of Cat Eyebrow Hair Loss

Grooming Habits and Shedding

It’s normal for cats to shed more during seasonal changes, but excessive grooming and licking can lead to hair loss and even bald spots. Cats feeling stressed or anxious may overgroom as a self-soothing behavior.

Using a soft grooming brush and regularly trimming mats and tangles can help reduce shedding and overgrooming.

Skin Conditions and Parasites

Skin irritations from allergies, infections, or parasites like fleas and mites can all prompt increased scratching, licking, and rubbing. This leads to broken hairs, bald patches, and even wounds or scabs on the skin. Treating the underlying condition will allow the fur to regrow over time.

For example, Revolution® kills fleas and treats ear mites to eliminate the itching sensation causing your cat discomfort.

Injuries and Trauma

Injuries from bites or scratches in a fight with another animal, getting hit by a car, or other physical trauma can damage hair follicles leading to temporary or permanent bald spots. Severe injuries may require stitches and antibiotics to help facilitate healing.

Consulting your veterinarian can determine suitable treatment options.

Hormonal Imbalances and Disease

Various feline diseases like diabetes or hyperthyroidism can spur hormonal shifts that affect the hair growth cycle. The overactive adrenal glands associated with Cushing’s disease often cause symmetrical hair loss on both sides of the body.

In many cases, treating the underlying condition helps restore fur regrowth over the span of several months. Early disease detection and specialized veterinary care aid the recovery process.

Do Cat Eyebrows Grow Back After Shaving or Plucking?

A cat’s eyebrows, also called whisker pads, serve an important sensory function. Located above the eyes, the eyebrows contain nerve endings that are part of the cat’s sophisticated whisker system. When a cat’s whiskers detect stimuli, signals travel to the eyebrows and then the brain, helping the cat gather information about its surroundings.

If you shave or pluck your cat’s eyebrows, they will usually grow back over time. However, the regrowth process can take weeks or even months. Additionally, repeatedly removing the eyebrows may damage the hair follicles and nerve endings, impacting proper regrowth.

The Cat Eyebrow Regrowth Process

Each cat eyebrow hair sits inside its own follicle under the skin. The follicle contains cells that produce keratin, the protein that makes up hair. As new cells form, they push old cells up and out of the skin, causing the hair to grow.

When you pluck an eyebrow hair, you remove the entire hair including the root. Shaving only cuts off the hair shaft above the surface of the skin. In both cases, the cells inside the follicle are still intact and will continue to generate new hair cells.

As the new cells accumulate, they will push a new hair up and out.

Initial eyebrow hair regrowth may start to be visible above the surface of the skin in 2-6 weeks. However, it often takes 3 months or more for the hair to regrow to its previous length, thickness, and sensory ability. The regeneration timeframe varies based on factors like the cat’s health and age.

Risks of Repeated Plucking or Shaving

While cat eyebrows tend to be resilient, repeated hair removal can cause long term damage. If the same hairs are plucked over and over, the constant stress on the follicles may destroy them. The nerves in the whisker pad area may also become irritated or inflamed.

Eventually, scar tissue can build up in the follicles and nerve endings, preventing regeneration. If this happens, your cat may permanently lose sensation in areas of its eyebrows and face.

In addition to physiological disruptions, behavior problems might arise. If your cat’s spatial awareness or \”whisker vision\” is impaired due to eyebrow loss, it may seem confused, frightened, or unusually clumsy.

Some cat owners think a hairless eyebrow look is cute or funny. However, it’s best not to tamper with your cat’s delicate sensory system just for cosmetic reasons. The eyebrows serve a crucial function for your cat’s comfort and safety.

What to Do If Your Cat’s Eyebrows Are Removed

Sometimes accidents happen. If your cat’s eyebrows get shaved at the groomer or plucked by a curious child, don’t panic. Just allow the area to fully heal before continually aggravating it by attempting mechanical hair removal again.

While you wait for regrowth, you can support the process by applying a healing ointment made with vitamin E. Ensure your cat’s food is rich in nutrients like omega fatty acids and vitamin B that assist with skin and coat health.

Most importantly, give those brows some TLC during the regrowth period. Avoid handling your cat’s face unnecessarily so the sensitive area isn’t disturbed. Recovery time will vary based on factors like your cat’s age, but diligent care can help your cat regain its lush, expressive eyebrows.

Encouraging Your Cat’s Eyebrow Regrowth

Ruling Out Underlying Conditions

Before trying to encourage eyebrow regrowth in cats, it’s important to rule out any underlying medical conditions that may be causing hair loss in that area. Schedule a veterinarian appointment to diagnose skin issues like allergies, infections, parasites, or hormonal imbalances that could be making your cat’s eyebrows fall out.

Treating these underlying problems is key for allowing healthy regrowth.

Providing Proper Nutrition

Giving your cat top-notch nutrition supports skin and coat health from the inside out. Make sure your cat’s diet includes high-quality proteins, healthy fats, vitamins, and minerals. Supplementing food with salmon oil, coconut oil, or fish oil adds beneficial fatty acids.

Proper hydration is also essential—keep fresh, clean water available at all times.

Using Conditioners and Supplements

Certain shampoos, conditioners, serums, and supplements are specifically designed to encourage eyebrow hair regrowth in cats. Look for products containing ingredients like melatonin, biotin, collagen, keratin, and amino acids.

Gently massaging conditioner into the brow area daily may stimulate blood flow and nourish hair follicles. When used alongside proper nutrition and medical care, these items support optimal regrowth.

Be patient, as it can take weeks or months for significant eyebrow hair to fill back in. Monitor your cat for signs of irritation. If products cause redness or inflammation, discontinue use. With diligent care both inside and out, your cat’s fabulous brows should return over time!

When to See the Veterinarian About Eyebrow Hair Loss

Eyebrow hair loss in cats can be concerning for pet parents. While some shedding is normal, excessive or patchy hair loss may indicate an underlying issue. Here’s a guide on when you should take your cat to see the veterinarian about eyebrow hair loss:

Sudden or Rapid Hair Loss

If your cat’s eyebrows seem to fall out very quickly, within a few days or weeks, a veterinary visit is a good idea. Rapid hair loss can signal an infection, parasite, or hormonal issue that needs treatment.

Partial or Patchy Hair Loss

It’s normal for eyebrow hairs to thin as cats age. But if your cat has bald patches or is missing chunks of eyebrow hair, it could indicate a skin condition like dermatitis, ringworm, or mites.

Hair Loss with Scratching or Redness

Feline hair loss is often accompanied by scratching, licking, or rubbing. Red, inflamed skin may also be present. This can point to allergies or skin infections requiring medication.

Hair Loss with Other Symptoms

If your cat’s eyebrow shedding occurs along with lethargy, appetite changes, or gastrointestinal issues, a vet visit helps identify if an underlying illness is the culprit.

No Regrowth After Shedding

It’s normal for cats to shed old eyebrow hairs. But if weeks pass without any regrowth, it may indicate an eyebrow hair cycle disruption warranting investigation.

Senior Cats with Hair Loss

Senior cats are prone to developing endocrine disorders like hyperthyroidism, which can cause eyelid hair loss. Vet exams help diagnose these diseases early.


In most cases, cat eyebrows will gradually regrow on their own as long as there is no medical condition causing permanent hair follicle damage. However, drastic or persistent eyebrow hair loss should be evaluated by your veterinarian to diagnose and treat any underlying problems.

With patience and a healthy environment, your cat’s fabulous brows should return over time. Pay attention to any changes and talk to your vet if you have concerns about permanent eyebrow hair loss.
