Why Is My Hair Falling Out? Understanding Hair Loss Causes and Symptoms

Hair loss, also known as alopecia, is a common concern that can affect anyone, impacting just the scalp or the entire body. It can be a temporary issue or a more permanent condition. Understanding why your hair is falling out involves exploring various factors, ranging from genetics and hormonal shifts to medical conditions and even lifestyle choices. While hair loss on the head is more frequently observed in men, it’s a problem that affects people of all genders and ages.

Baldness, in particular, refers to significant hair loss from the scalp. The most prevalent cause of baldness is hereditary hair loss associated with aging. For some, accepting hair loss as a natural process is preferable, and they may choose to manage it with hairstyles or accessories like hats and scarves. Others seek treatments to halt further hair loss or stimulate regrowth.

Before deciding on any course of action for hair loss, it’s crucial to consult with a healthcare professional. A doctor can help pinpoint the underlying cause of your hair loss and discuss appropriate treatment options tailored to your specific situation.

Symptoms of Hair Loss: Recognizing the Signs

Hair loss manifests in diverse ways, depending on the underlying cause. It can develop abruptly or gradually, affecting solely the scalp or extending to the entire body. Recognizing the symptoms is the first step in addressing the issue.

Male-Pattern Baldness

Male-pattern baldness is a very common type of hair loss, often starting with a receding hairline at the forehead or thinning at the top of the head (the crown). This condition can progress, leading to partial or complete baldness in many men as they age. The pattern is typically predictable, beginning at the front and top of the scalp.

Female-Pattern Baldness

Female-pattern baldness presents differently, generally beginning with a gradual thinning of hair across the scalp. Many women initially notice hair thinning and increased hair loss particularly along their usual hair part and on the central top portion of the head. Unlike men, women are less likely to experience a receding hairline.

Patchy Hair Loss (Alopecia Areata)

Alopecia areata is characterized by sudden, patchy hair loss. It usually starts with one or more circular bald patches, which may overlap and become more noticeable over time. Some individuals might experience an itchy or painful scalp before the hair in these patches falls out. This type of hair loss is an autoimmune condition where the body’s immune system mistakenly attacks hair follicles.

Traction Alopecia

Traction alopecia is hair loss caused by hairstyles that repeatedly pull on your hair. Styles like tight pigtails, braids, cornrows, or the frequent use of tight hair rollers can lead to this condition. The constant pulling force damages the hair follicles, resulting in hair loss, particularly around the hairline and temples.

Frontal Fibrosing Alopecia

Frontal fibrosing alopecia is a type of hair loss characterized by a receding hairline, primarily affecting older women. The cause of this condition remains unknown, but it leads to scarring of the scalp and permanent hair loss along the front of the scalp. Early diagnosis and treatment are important to potentially slow down its progression.

Beyond these specific patterns, general signs and symptoms of hair loss can include:

• Gradual thinning on the top of the head: This is the most prevalent type of hair loss as people age. In men, it often starts as a receding hairline. Women typically notice a widening of their hair part. Frontal fibrosing alopecia is also becoming more common in older women, presenting as a receding hairline.
• Circular or patchy bald spots: Some people experience smooth, coin-sized bald spots, which can occur on the scalp, beard, or eyebrows. The skin in these areas may become itchy or painful before hair loss is noticeable.
• Sudden loosening of hair: Physical or emotional shocks can trigger sudden hair shedding. Handfuls of hair may come out when washing, combing, or even gently pulling your hair. This type of hair loss, known as telogen effluvium, is usually temporary and results in overall hair thinning.
• Full-body hair loss: Certain medical conditions and treatments, such as chemotherapy for cancer, can cause hair loss across the entire body. In most cases, the hair will grow back once the treatment ends. This type of hair loss is called anagen effluvium.
• Patches of scaling that spread over the scalp: This symptom is indicative of ringworm, a fungal infection. It may be accompanied by broken hair, redness, swelling, and sometimes oozing.

When Should You See a Doctor for Hair Loss?

It’s advisable to consult your doctor if you are concerned or distressed about persistent hair loss, whether it’s for yourself or your child, and if you’re considering treatment options. For women noticing a receding hairline, especially indicative of frontal fibrosing alopecia, early consultation is important to discuss potential treatments to minimize permanent hair loss.

You should also seek medical advice if you experience sudden or patchy hair loss, or if you notice more than usual hair shedding when combing or washing hair. Sudden hair loss can sometimes be a sign of an underlying medical condition that requires diagnosis and treatment. Prompt medical attention can help identify the cause and guide appropriate management.

Common Causes: Why Is My Hair Falling Out?

It’s normal to lose 50 to 100 hairs per day. This amount of shedding is usually unnoticeable because new hair is growing simultaneously. Hair loss becomes apparent when this cycle is disrupted, and new hair doesn’t replace the hair that has fallen out. Several factors can contribute to this imbalance.

Hair loss is often linked to one or more of the following causes:

• Family history (heredity): The most prevalent cause of hair loss is a hereditary condition occurring with aging. This is known as androgenetic alopecia, encompassing male-pattern baldness and female-pattern baldness. It follows predictable patterns: receding hairline and bald spots in men, and overall thinning at the crown in women. Genetic predisposition plays a significant role in these common types of hair loss.
• Hormonal changes and medical conditions: Various conditions and hormonal fluctuations can trigger temporary or permanent hair loss. These include hormonal shifts during pregnancy, childbirth, menopause, and thyroid problems. Medical conditions such as alopecia areata (an autoimmune disorder causing patchy hair loss), scalp infections like ringworm, and trichotillomania (a hair-pulling disorder) are also significant causes.
• Medications and supplements: Hair loss can be a side effect of certain medications. Drugs used for treating conditions like cancer, arthritis, depression, heart problems, gout, and high blood pressure can sometimes contribute to hair shedding.
• Radiation therapy to the head: Radiation treatment to the head can result in hair loss. While hair often regrows after treatment, it may not return to its original density or texture.
• A very stressful event: Experiencing significant physical or emotional stress can lead to a general thinning of hair. This condition, known as telogen effluvium, typically becomes noticeable several months after the stressful event and is usually temporary.
• Hairstyles and treatments: Excessive hairstyling or hairstyles that pull the hair tightly can cause traction alopecia. Frequent use of hot-oil treatments and permanents can also damage the hair and lead to hair loss. If scarring of the hair follicles occurs, the hair loss can become permanent.

Risk Factors for Hair Loss

Several factors can increase your likelihood of experiencing hair loss:

• Family history of balding: Having a family history of baldness, from either your mother’s or father’s side, increases your risk of developing similar hair loss patterns.
• Age: Hair loss becomes more common as you age, with androgenetic alopecia being increasingly prevalent in older individuals.
• Significant weight loss: Experiencing substantial weight loss, whether intentional or unintentional, can sometimes trigger hair loss.
• Certain medical conditions: Conditions like diabetes and lupus are associated with an increased risk of hair loss.
• Stress: High levels of stress can contribute to various types of hair loss, including telogen effluvium and trichotillomania.
• Poor nutrition: Nutritional deficiencies, especially in protein, iron, and zinc, can impact hair health and contribute to hair loss.

Prevention Tips for Hair Loss

While genetic hair loss (male-pattern and female-pattern baldness) is largely unpreventable, you can take steps to minimize other types of hair loss:

• Be gentle with your hair: Use a detangler and avoid harsh pulling when brushing or combing, especially when hair is wet and more fragile. A wide-toothed comb can be helpful. Limit harsh treatments such as hot rollers, curling irons, hot-oil treatments, and permanents. Reduce tension from hairstyles that use rubber bands, barrettes, and tight braids.
• Review medications and supplements: Discuss with your doctor any medications or supplements you are taking that might list hair loss as a side effect. There may be alternative medications available.
• Protect your hair from UV radiation: Excessive sun exposure can damage hair. Protect your hair from prolonged sunlight and other sources of ultraviolet light.
• Stop smoking: Some studies suggest a link between smoking and increased baldness in men. Quitting smoking is beneficial for overall health and may also benefit hair health.
• Consider a cooling cap during chemotherapy: If you are undergoing chemotherapy, ask your doctor about using a cooling cap. These caps can reduce blood flow to the scalp, potentially minimizing hair loss during chemotherapy treatments.

By understanding the various causes and symptoms of hair loss, and by taking preventive measures, you can be proactive in managing your hair health. If you are concerned about hair loss, consulting with a healthcare provider is the best step to determine the cause and explore appropriate solutions.
