Hair loss, also known as alopecia, is a common concern that can affect anyone, impacting the scalp or the entire body. It can be temporary or permanent, stemming from various factors such as heredity, hormonal fluctuations, underlying medical conditions, or simply the natural aging process. While hair loss can occur in anyone, it is often more noticeable and prevalent in men.
Baldness, specifically, refers to excessive hair loss from the scalp. The most frequent cause is hereditary hair loss associated with aging. Individuals respond to hair loss differently; some embrace it, others conceal it with different methods, and some seek treatments to halt further loss or stimulate regrowth.
If you’re considering hair loss treatments, it’s crucial to first consult with your doctor to determine the underlying cause of your hair loss and explore the most appropriate treatment options for your specific situation.

Symptoms of Hair Loss: Recognizing the Signs
Hair loss can manifest in various ways, depending on the cause. It can begin abruptly or gradually, and affect solely the scalp or extend to the entire body. Recognizing the patterns and symptoms is the first step in understanding why your hair might be falling out.
Male-Pattern Baldness: The Receding Hairline
Male-pattern baldness is a very common type of hair loss in men. It typically begins with a receding hairline, where the hair gradually thins and recedes from the forehead. This can progress to involve the top of the head as well, leading to partial or even complete baldness in some cases. The pattern is usually quite predictable, starting at the temples and crown.
Female-Pattern Baldness: Thinning Hair and Widening Part
Female-pattern baldness, while sharing a similar name with its male counterpart, presents differently. It typically starts with a gradual thinning of hair all over the scalp, but is often most noticeable at the part line. Many women first observe thinning and hair loss where they part their hair and on the top-central portion of the head. Unlike men, women are less likely to experience a receding hairline.
Patchy Hair Loss (Alopecia Areata): Sudden Bald Spots
Alopecia areata is a type of hair loss characterized by the sudden appearance of smooth, circular bald patches. These patches can occur anywhere on the scalp, beard, or eyebrows and may sometimes overlap, creating larger areas of hair loss. In some cases, the onset of alopecia areata may be preceded by an itchy or painful sensation in the affected area. This condition is an autoimmune disorder where the body’s immune system mistakenly attacks hair follicles.
Traction Alopecia: Hair Loss from Tight Hairstyles
Traction alopecia is hair loss caused by repeated pulling or tension on the hair shafts. This can result from hairstyles like tight pigtails, braids, cornrows, or the frequent use of tight hair rollers. Over time, the constant stress on hair follicles can lead to damage and hair loss. Recognizing and changing these hairstyles early can often prevent permanent hair loss.
Frontal Fibrosing Alopecia: Receding Hairline in Older Women
Frontal fibrosing alopecia is a less common form of hair loss that primarily affects older women. It’s characterized by a gradually receding hairline, particularly at the front and temples. The cause of frontal fibrosing alopecia is not fully understood, but early treatment might help slow its progression and potentially avoid significant permanent hair loss.
Besides these specific patterns, general signs and symptoms of hair loss can include:
- Gradual thinning on top of the head: As mentioned, this is the most prevalent type, seen in both men and women as they age. Men often notice a receding hairline, while women experience a broadening of the part in their hair. Frontal fibrosing alopecia is also becoming increasingly recognized as a pattern in older women.
- Circular or patchy bald spots: Alopecia areata is the primary cause of these spots, appearing on the scalp, beard, or eyebrows. Itching or pain may precede the hair falling out.
- Sudden loosening of hair: Physical or emotional shocks can trigger telogen effluvium, causing hair to loosen and shed in handfuls when combing, washing, or even gently tugging. This type is usually temporary, leading to overall thinning.
- Full-body hair loss: Certain medical treatments, like chemotherapy for cancer, and some medical conditions can cause hair loss all over the body (alopecia universalis). Hair usually regrows after treatments conclude.
- Patches of scaling that spread over the scalp: This symptom is indicative of ringworm, a fungal infection. It can be accompanied by broken hair, redness, swelling, and sometimes oozing.
When to Seek Medical Advice for Hair Loss
It’s important to see a doctor if you are concerned or distressed by persistent hair loss in yourself or your child and are considering treatment options. For women noticing a receding hairline (frontal fibrosing alopecia), consulting a doctor for early intervention is advised to potentially prevent significant permanent hair loss.
Furthermore, seek medical advice if you experience:
- Sudden or unexplained hair loss.
- Patchy hair loss.
- More than usual hair loss when combing or washing hair.
- Hair loss associated with scalp pain or itching.
Sudden or unusual hair loss can be a sign of an underlying medical condition that requires diagnosis and treatment. A healthcare professional can help determine the cause of your hair loss and guide you on the best course of action.
Causes of Hair Loss: Unraveling the Reasons
It’s normal to lose 50 to 100 hairs a day; this is usually unnoticeable as new hair is simultaneously growing. Hair loss becomes apparent when new hair fails to replace the hair that has fallen out. Understanding the causes is crucial in addressing “Why Does My Hair Keep Falling Out?”. Hair loss is often linked to one or more of the following factors:
- 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. Your genes play a significant role in determining your likelihood of experiencing this type of hair loss.
- Hormonal changes and medical conditions: Various conditions can induce temporary or permanent hair loss. Hormonal shifts related to pregnancy, childbirth, menopause, and thyroid issues are common culprits. Medical conditions like alopecia areata (an autoimmune condition), scalp infections such as ringworm, and trichotillomania (a hair-pulling disorder) can also lead to hair loss. Fluctuations in hormones, especially androgens, can significantly impact hair growth cycles.
- Medications and supplements: Hair loss can be a side effect of certain medications, including drugs used for cancer chemotherapy, arthritis, depression, heart problems, gout, and high blood pressure. If you’ve recently started a new medication and notice hair loss, it’s worth discussing with your doctor.
- Radiation therapy to the head: Radiation treatment to the head, often used for cancer therapy, can result in hair loss. In some cases, hair regrowth may not be complete, and the texture or density might be different than before.
- A very stressful event: Experiencing a significant physical or emotional shock can lead to telogen effluvium, a temporary type of hair loss. Many people notice general hair thinning several months after a stressful event. This type of hair loss is usually reversible once the body recovers from the stressor.
- Hairstyles and treatments: As mentioned earlier, excessive hairstyling or hairstyles that pull on your hair (traction alopecia) can cause hair loss. Hot-oil hair treatments, permanents, and chemical relaxers can also damage the hair and scalp, leading to hair fall. If scarring occurs from these treatments, hair loss can become permanent.

Risk Factors for Hair Loss: Identifying Vulnerabilities
Several factors can increase your susceptibility to hair loss. Recognizing these risk factors can help you understand your individual predisposition:
- Family history of balding: Having a family history of baldness, from either your mother’s or father’s side, significantly increases your risk of developing androgenetic alopecia.
- Age: Hair loss becomes more common as you age. The hair growth cycle shortens, and hair follicles may shrink, leading to thinning and slower regrowth.
- Significant weight loss: Sudden or significant weight loss can be a physical stressor on the body, potentially triggering telogen effluvium and temporary hair loss.
- Certain medical conditions: Conditions like diabetes and lupus are associated with an increased risk of hair loss. These systemic conditions can affect various bodily functions, including hair growth.
- Stress: While everyday stress is unlikely to cause long-term hair loss, significant or chronic stress can contribute to telogen effluvium.
- Poor nutrition: Nutritional deficiencies, especially in iron, zinc, and protein, can impact hair health and contribute to hair loss. A balanced diet is essential for healthy hair growth.
Prevention of Hair Loss: Protective Measures
While most baldness due to genetics (male-pattern and female-pattern baldness) is not preventable, you can take steps to prevent other types of hair loss and maintain healthier hair:
- Be gentle with your hair: Avoid harsh treatments and excessive manipulation. Use a detangler and be gentle when brushing and combing, especially when hair is wet and more fragile. A wide-toothed comb can minimize pulling.
- Avoid harsh treatments: Limit the use of hot rollers, curling irons, hot-oil treatments, permanents, and chemical relaxers, as these can damage hair and scalp.
- Limit tension hairstyles: Minimize hairstyles that pull tightly on the hair, such as tight braids, buns, and ponytails that use rubber bands or barrettes.
- Consult your doctor about medications: Discuss any medications or supplements you are taking with your doctor to see if hair loss is a potential side effect, and explore alternatives if necessary.
- Protect your hair from sunlight: Excessive exposure to ultraviolet (UV) light can damage hair. Use hats or hair products with UV protection when spending extended time in the sun.
- Stop smoking: Studies have indicated a link between smoking and baldness, particularly in men. Quitting smoking has numerous health benefits, including potential benefits for hair health.
- Consider a cooling cap during chemotherapy: If undergoing chemotherapy, ask your doctor about cooling caps. These devices can help reduce hair loss during treatment by cooling the scalp and reducing blood flow to hair follicles.
By adopting these preventative measures and understanding the various causes of hair loss, you can take proactive steps to maintain healthy hair and address concerns about “why does my hair keep falling out?”. Remember to consult with a healthcare professional for personalized advice and treatment options if you are experiencing persistent or concerning hair loss.
