Moles, those small, dark spots on our skin, are a common feature for many. Often called beauty marks, they can add character and uniqueness. But if you’ve noticed hair sprouting from one of your moles, you might be wondering if it’s normal or a cause for concern. It’s a question that often pops up: Why Do Moles Grow Hair?
This article delves into the reasons behind hairy moles, exploring what they signify about your skin health and when it’s time to consult a dermatologist. We’ll break down the science behind moles and hair growth, address common anxieties about cancer risks, and offer practical advice on managing hairy moles.
What Exactly Are Moles?
To understand why moles grow hair, it’s helpful to first understand what moles are. In simple terms, moles are clusters of skin cells. Medically known as melanocytes, these cells are responsible for producing melanin, the pigment that gives our skin its color. According to the Mayo Clinic, most people develop between 10 to 45 moles during childhood and adolescence. While some moles may fade over time, many remain throughout adulthood.
Dr. Paul Curtiss, a board-certified dermatologist with U.S. Dermatology Partners Carrollton, explains, “Melanocytes are normally distributed throughout our skin, and impart its natural pigment. It’s normal to have several collections of moles which develop early on in life.”
Moles can appear virtually anywhere on the body – from your arms and face to less visible areas. For the most part, moles are benign. However, in rare instances, a mole, including a hairy mole, can become cancerous. Knowing the signs of healthy versus potentially problematic moles is key to proactive skin health.
The Connection: Moles and Hair Growth
So, why do some moles grow hair while others remain smooth? The answer lies in the structure of our skin. Moles themselves don’t inherently cause hair growth, but they can develop in areas where hair follicles already exist.
Dr. Curtiss clarifies, “Moles are normal structures within our skin and don’t normally impede other structures in our skin. As such, moles in normal hair-bearing areas (which are most areas of the body except for our palms and soles) may grow hair.”
Essentially, if a mole forms on top of or around a hair follicle, the follicle continues its natural cycle of hair production. The hair simply emerges through the mole, just as it would through normal skin. This is similar to how hair can sometimes grow from a pimple – the skin structure, including hair follicles, remains functional even within these skin developments.
Hairy Moles and Cancer: Separating Fact from Fiction
One of the primary concerns people have about hairy moles is the potential link to skin cancer, particularly melanoma. It’s crucial to understand that having hair growing from a mole is not automatically a sign of cancer. Melanoma, a serious form of skin cancer, is relatively rare, accounting for only about 1% of all skin cancers, according to the American Cancer Society.
Dr. Curtiss reassures, “Generally, a hair within a normal-appearing mole is not a sign of cancer.” He outlines the characteristics of a typical, benign mole:
- Consistent Color: Usually brown, tan, or black with an even shade throughout.
- Regular Shape: Typically round or oval with well-defined borders.
- Texture: Can be flat or slightly raised.
- Size: Generally less than six millimeters in diameter (about ¼ inch).
Most moles remain harmless throughout life. However, it’s vital to be aware of the signs that could indicate melanoma or another form of skin cancer. Dr. Curtiss highlights the ABCDEs of melanoma detection – changes to watch for in a mole:
- Asymmetry: One half of the mole does not match the other half.
- Border Irregularity: The edges are notched, uneven, or blurred.
- Color Changes: Variations in color within the mole, or a change in color overall (e.g., from tan to darker brown or black).
- Diameter: Growth in size, especially if larger than 6 millimeters.
- Evolution: Any change in the mole – in size, shape, elevation, color, itching, bleeding, or crusting.
If you observe any of these changes or have concerns about a new mole, it’s essential to consult your doctor. They may recommend a dermatologist for a thorough skin examination to determine if your moles are benign or require further investigation.
Managing Hairy Moles: Removal and Hair Management
While hairy moles are usually not dangerous, some individuals may find the hair growth bothersome for cosmetic reasons. Fortunately, there are ways to manage both the hair and the mole itself.
For hair removal, Dr. Curtiss suggests common methods like shaving, waxing, or plucking. “The hairs that grow out of moles can easily be shaved, waxed, or plucked. (Just make sure the method you use is gentle enough that it doesn’t break the skin.)” It’s important to use gentle techniques to avoid skin irritation or damage.
If you wish to remove the mole entirely, this requires a procedure performed by a dermatologist. “And in order to completely remove the mole itself, they have to be cut off,” Dr. Curtiss explains. Mole removal is a relatively quick procedure that can be done for cosmetic reasons or if there is a medical concern about the mole.
However, Dr. Curtiss cautions against laser hair removal on moles. “Treatments like laser hair removal should be avoided over moles, as the laser may have trouble localizing energy to the hair follicle, instead [targeting] pigment within the mole.” Laser treatments can potentially cause discoloration of the mole, making it appear worse rather than resolving the hair issue.
When to Seek Professional Advice
Regular skin checks are a crucial part of maintaining skin health. It’s generally recommended to see a dermatologist if you notice any new moles or changes in existing ones.
Dr. Curtiss advises, “While it’s normal for moles to appear during childhood, you should develop less new moles [as you age]. New moles after age 30 can be harmless, but likely should be checked out by your health-care provider.”
Even if a mole appears benign, professional skin checks are proactive. Dermatologists can provide guidance on how often you should have your skin examined and address any specific concerns you might have about your moles, hairy or otherwise. Early detection is key in managing any potential skin issues, making routine checks a valuable part of your healthcare.
Frequently Asked Questions About Hairy Moles
Why do hairs from moles sometimes seem thicker?
Moles don’t disrupt the normal function of hair follicles. If a mole develops in an area with strong hair roots, like the arms or chin, the hair growing through it may appear thicker and coarser. This is often why hairs from moles on limbs can be more noticeable than those on areas with finer hair.
Is there a reason for different hair types growing from moles?
The appearance of hair from moles can vary. You might see different colors and textures depending on the location of the mole and your natural hair type. For example, gray or white hairs might appear in moles near the hairline, especially as you age and develop gray hairs elsewhere. The melanocytes within the mole, responsible for pigment, can also influence the color of the hair growing from it.
Is it good luck if a mole grows hair?
You may have heard the folklore that a hairy mole is a sign of good luck. This belief originates from Chinese tradition, associating it with fortune and prosperity. While there’s no scientific basis for this, the presence of hair does indicate a healthy hair follicle beneath the mole, which in itself is a positive sign of skin function.
In Conclusion
Hairy moles are typically a normal skin feature and not a cause for alarm. The hair growth is simply a result of hair follicles functioning beneath the mole’s surface. While most hairy moles are benign, it’s important to monitor all moles for changes in size, shape, color, or any new symptoms. Regular skin self-exams and professional dermatologist check-ups are the best way to ensure your skin health and address any concerns proactively. If you have any worries about a hairy mole or any other skin changes, seeking advice from a dermatologist is always the most prudent step.
