Ever wondered if chimpanzees can go bald? Turns out, they can.
Just like us, chimps can lose hair as they age, or because of stress, illness, and a few other things. Male chimps often get bald spots on their heads when they’re older—honestly, it looks a lot like male pattern baldness in humans.
You might picture chimps with thick, wild fur all over, but their hair can thin out or vanish in spots. Sometimes, stress or social habits—like yanking each other’s hair—leave them with patchy baldness.
That can make a chimp look pretty different, sometimes even a little odd or unexpected.
Their hair loss affects more than just looks. It can influence their health and social standing, and scientists even study bald chimps to learn more about human biology. There’s something oddly fascinating about the way this trait connects us with our primate cousins.

Do Chimpanzees Go Bald Naturally?
Most chimps have thick fur all over their bodies. Still, some of them start losing hair as they get older, or because of genetics or life in captivity.
Their hair loss can look a bit like what happens to humans, but with its own quirks.
Typical Hair Patterns in Chimps
Chimpanzees usually have dark brown or black hair that covers almost everything. The longest hair grows on their backs and shoulders, and sometimes it can get up to 20 cm long.
Their limbs and bellies have shorter hair. Faces, palms, soles, and fingers are mostly bare.
This uneven fur helps them move around and survive in the forest. Most chimps hold onto their fur unless age or health issues step in.
Incidents of Hair Loss in Captivity
Chimps living in captivity lose hair more often than wild ones. Stress from tight spaces or not enough social time cranks up their cortisol levels.
When cortisol rises, hair starts to thin or fall out. Some chimps pull their own hair or rub against things, leaving bald patches.
Parasites like mites or fungal infections can also make them lose fur. If caretakers provide good enrichment and care, it helps a lot.
Genetic and Age-Related Hair Loss
Older chimps sometimes get bald spots, kind of like people do. This hair loss (androgenetic alopecia) mostly hits male chimps.
It usually shows up when they reach their late 20s or early 30s. Changes in hormones, especially testosterone, drive this.
Female chimps can lose hair too, but it’s less common. Genetics definitely play a role, so some chimps just shed more as they age.
You’ll see things like a receding hairline or a thinning crown, which is strangely familiar.
Human vs. Chimpanzee Baldness
Chimps and humans both lose hair because of hormones and aging, but their baldness looks different. Chimps don’t really get the same clear patterns we see in people.
Chimps are more likely to lose fur because of disease, stress, or parasites. Humans usually keep scalp hair but lose body hair, while chimps can lose fur almost anywhere.
If you’re curious, there’s more on this in the discussion on hair loss in chimps.
Causes and Comparisons of Baldness in Primates and Other Animals
Primates like chimps lose hair for a bunch of reasons, and their baldness doesn’t always look like ours. Stress, health issues, and social habits all matter.
Some other animals—like stump-tailed macaques or certain dog breeds—show their own odd baldness patterns too.
Alopecia and Stress-Induced Hair Loss in Chimps
Alopecia causes sudden hair loss in chimps. Their immune system starts attacking hair follicles, and fur vanishes in patches.
Bald spots can pop up fast, and that’s stressful for the chimp. Stress itself also triggers hair loss.
When chimps feel stressed, their hormones shift, and their hair gets weaker. Young chimps separated from their groups often lose fur because of emotional stress.
That’s actually pretty similar to how stress causes hair loss in people.
Impact of Overgrooming and Social Behavior
Grooming matters a lot to chimps. It helps them bond and keep clean.
If chimps don’t groom much—maybe because they’re stressed or isolated—their fur can get scruffy and thin. Sometimes, chimps or other apes groom too much, and that causes hair loss too.
Overgrooming usually comes from anxiety or social tension. When grooming habits change, their fur definitely takes a hit.
How Baldness Occurs in Other Species
Some animals besides primates go bald, though the reasons and patterns aren’t always the same. For example, stump-tailed macaques start losing hair as they get older.
Older males seem to lose hair more often, and researchers usually link this to hormone changes. Their baldness looks a bit like human male pattern baldness, but it’s not quite the same thing.
A couple of dog breeds, like dachshunds and greyhounds, also deal with male pattern baldness. Unlike alopecia, this type of baldness follows a certain pattern and gets passed down through their genes.
So, baldness can show up in all sorts of ways depending on the animal, their hormones, and their genetics. Kind of fascinating, right?
