Does Cat Fur Grow Back: Understanding Cat Hair Regrowth and Why It Does Not Always Occur

Yes, cat fur grows back. However, if your cat’s hair is not growing back, there are many reasons. Some more common causes of cat hair loss include alopecia (a condition that results in bald patches), mange (an infection of the skin caused by mites), and fungus infections.

If any of these problems are affecting your cat, it’s essential to seek veterinary care as soon as possible to begin treatment. However, with early intervention, most cats can recover from hair loss and enjoy healthy scalps again!

Growing Back Cat Hair in Various Situations

After Shaving

Most cats will grow back their hair after a shave, but some may not. However, if your cat doesn’t grow back their hair after a shave, it’s possible that the hair was shaved too short and is now hidden beneath the skin.

It’s important to periodically inspect the areas around your cat’s neck and face for any evidence of shaving (i.e., redness, bumps). If you notice any shaving, immediately take your cat to the vet for evaluation. In the meantime, keep a close eye on your cat to ensure they are doing okay.

After Ear Mites

Cat hair will not grow back after ear mites, but if treated early enough with an over-the-counter medication, most cats can regrow their hair within a few weeks post-infection.

If your cat’s ears are red and swollen, they likely have ear mites and should be checked out by a vet ASAP! For those unlucky few whose cat’s hair does not grow back after treatment – there is no need to despair as many people find success using other methods, such as shampooing or steam cleaning their pet’s ears several times per week.

After Fleas

Fleas can be a significant problem for cat owners, and they can cause a lot of hair loss. If you catch the problem early on, you can stop the hair loss from happening altogether.

You will need to treat your cat for fleas and put medicinal drops on them daily for a month. For example, consult with a vet if you are unsure how to proceed or have any other questions. In the meantime, keep your cat groomed regularly to prevent hair loss from happening in the first place.

After Ringworm

Hair loss from ringworm is not always permanent, but it can be severe and require treatment. If you notice bald patches or hair loss, see your doctor immediately for an examination and treatment plan.

Ringworm is a fungal infection that can affect cats of all ages. It’s usually yellow and itchy and can spread quickly through the cat’s fur. If you think your cat may have ringworm, take them to the vet for a diagnosis.

While most cases of ringworm respond well to therapy, some do not recover completely. If this is the case for you, you must consult a doctor to avoid long-term damage or cosmetic concerns such as thinning hair or a receding scalp line.

Treatment typically involves using topical medication to kill the fungus and reduce inflammation. After treatment, your cat may need to be confined for a few days while the area heals.

Whether hair loss is a minor inconvenience or a significant concern, you should not take ringworm lightly. Instead, take the time to get checked out and get on the path to hair regrowth – it’ll be worth it!

Over Scars

Cat fur grows back over scars, but it may not be as full or dense as before the injury. If you’d like to keep the spot looking its best, trimming the hair around it every few weeks is a good idea.

Also, ensure to keep the cat clean and groomed so that hair doesn’t accumulate around the scar.

Why a Cat’s Hair Is Not Growing Back

Fur Shedding

Cats are known for their short hair, meaning they must shed it every few weeks. The length, density, and texture of your cat’s fur will determine how often it will clear. You can try different things to encourage your cat to keep its coat longer, like scratching posts or giving them toys that make noise when played with.

Dermatophytosis (Ringworm)

Cats are commonly affected by dermatophytosis, a fungal infection of the skin. This can happen at any age and is often caused by environmental stressors such as climate changes or new home pets.

If you notice your cat has bald patches on its skin, it’s best to take them to the vet for a check-up. Treatment options include anti-fungal medication and topical creams.

External Parasites

If you own a cat, they are likely infected with external parasites. These parasites can affect your cat’s hair growth and make it difficult to regrow hair. Therefore, treating them regularly using specialized products is vital to keep them healthy and parasite-free.


Scabies is a skin disease caused by mites. They burrow into the skin and cause intense itching. The cat scratches and rubs against things, then transfer the mites to other people or animals they come in contact with.

If your cats catch scabies, it is challenging to get rid of – treatment involves antibiotics and a lot of care and attention. So it’s essential to keep your cat indoors so they can’t scratch at people or contaminate other cats with their infection until the condition is treated.


If you are experiencing a loss of fur on your pet and it isn’t due to health problems, there is a good chance that an allergy is the cause. Allergies can be caused by many environmental factors, including cat hair.

If changing your pet’s diet or introducing new allergens into their home doesn’t help, talk to your veterinarian about possible treatments such as injections or inhalers.


Stress is a significant contributor to hair loss in cats. When cats are stressed, their hair won’t grow back as fast. However, if the cat gets enough exercise and has a regular grooming schedule, its hair will usually regrow evenly. However, if another issue is causing stress in the home (such as another pet), it may also affect the cat’s hair growth.

Autoimmune Diseases

It is not uncommon for cats to suffer from autoimmune diseases. These diseases are caused by the body’s immune system going haywire and attacking its tissues.

The most common symptoms of these disorders include hair loss and skin lesions. Treatment usually involves a combination of drugs and vaccines. Still, if you notice any changes in your cat’s health, it is crucial to get them checked out by a veterinarian as soon as possible.
