Why Am I Losing My Hair? 12 Common Causes of Hair Loss in Women and Men
Hair loss is common, but it isn't always caused by genetics. Thinning hair, a widening part, a receding hairline, or increased shedding can have many possible causes, including hereditary hair loss, hormonal changes, nutritional deficiencies, stress, medications, and certain medical conditions.
At NOVA Hair and Skin Clinic in Fairfax, VA, we evaluate hair loss based on your individual pattern, history, and goals to help identify potential causes and develop a personalized treatment plan.
If you've recently noticed more hair in your shower drain or brush, you're not alone. The important question is: why is it happening?
1. Hereditary Hair Loss
One of the most common causes of hair loss is androgenetic alopecia, also called male pattern hair loss or female pattern hair loss.
Genetics can influence how your hair follicles respond to hormones and how long individual hairs remain in their growth phase.
In men, hereditary hair loss may appear as:
Receding temples
A thinning crown
A gradually expanding bald spot
Progressive thinning across the top of the scalp
In women, it may present as:
A widening center part
Reduced overall density
Thinning around the crown
A smaller ponytail
Increased scalp visibility
Because hereditary hair loss tends to progress gradually, early evaluation can be helpful.
2. Hormonal Changes
Hormones can have a significant effect on hair growth.
Women may experience increased shedding or thinning following:
Pregnancy
Childbirth
Menopause
Changes in hormonal contraception
Certain hormonal conditions
Conditions such as polycystic ovary syndrome (PCOS) can also be associated with androgen-related hair changes.
If your hair loss appears alongside irregular periods, acne, increased facial hair, or other hormonal symptoms, discussing these changes with a healthcare professional may be appropriate.
3. Stress and Illness
Significant physical or emotional stress can trigger a type of temporary hair shedding known as telogen effluvium.
Potential triggers include:
Major illness
Surgery
High fever
Significant emotional stress
Rapid weight loss
Severe dieting
Major lifestyle changes
With telogen effluvium, increased shedding may become noticeable several weeks or months after the triggering event.
The good news is that this type of shedding can often improve once the underlying trigger is addressed.
4. Nutritional Deficiencies
Your hair follicles require adequate nutrients to function normally.
Hair shedding can sometimes be associated with deficiencies involving nutrients such as:
Iron
Vitamin D
Zinc
Vitamin B12
Protein
However, taking supplements isn't necessarily the answer for everyone.
More isn't always better. Excessive supplementation can sometimes cause problems of its own. If nutritional deficiency is suspected, appropriate medical evaluation and laboratory testing can help determine whether supplementation is actually needed.
5. Thyroid Disorders
Both an underactive thyroid (hypothyroidism) and an overactive thyroid (hyperthyroidism) can affect the hair-growth cycle.
Hair changes associated with thyroid problems may include:
Increased shedding
Overall thinning
Dry or brittle hair
Changes in hair texture
Thinning of the outer eyebrows in some cases
If hair loss occurs alongside fatigue, unexplained weight changes, temperature sensitivity, or other thyroid-related symptoms, talk with your healthcare provider.
6. Medications
Some medications can contribute to hair shedding as a side effect.
Medication-related hair loss can occur with certain drugs used to treat conditions such as:
High blood pressure
Depression
Thyroid disorders
Blood clotting conditions
Autoimmune diseases
Cancer
Never stop a prescribed medication because of hair loss without speaking with the prescribing clinician.
If you believe a medication may be contributing to shedding, your healthcare provider can help determine whether an alternative is appropriate.
7. Autoimmune Conditions
Certain autoimmune conditions can affect hair follicles.
One example is alopecia areata, which can cause sudden, well-defined patches of hair loss on the scalp or other areas of the body.
Some people experience small patches, while others can develop more extensive hair loss.
Because autoimmune-related hair loss can require a different treatment approach than hereditary thinning, proper diagnosis is important.
8. Tight Hairstyles and Hair Practices
Repeated tension on the hair can contribute to traction alopecia.
This can occur with hairstyles that consistently pull on the follicles, including:
Tight ponytails
Braids
Cornrows
Extensions
Tight buns
Certain hairpieces
Repeated tension can eventually damage follicles.
Reducing tension early may help prevent additional damage. In more advanced cases, permanent follicular damage can occur.
9. Scalp Conditions
A healthy scalp provides the foundation for healthy hair growth.
Inflammation, infection, or other scalp disorders can contribute to shedding or hair loss.
Symptoms that deserve evaluation include:
Persistent itching
Scaling
Redness
Burning
Tenderness
Scalp sores
Sudden changes in hair density
Treating the underlying scalp condition may be an important part of addressing the hair loss.
10. Rapid Weight Loss and Restrictive Diets
Your body prioritizes essential functions when it isn't receiving adequate nutrition.
Significant calorie restriction, rapid weight loss, or diets lacking adequate protein and nutrients may trigger increased shedding.
If your hair loss began after a major change in weight or diet, tell your healthcare provider. The timing can provide an important clue when determining the cause.
11. Aging
Hair naturally changes as we get older.
Hair follicles may gradually produce finer strands, and the growth phase of individual hairs can become shorter.
As a result, you may notice:
Less overall density
Finer individual hairs
More visible scalp
Slower-growing hair
Changes in hair texture
Age-related changes can overlap with hereditary hair loss, making professional evaluation useful when thinning becomes noticeable.
12. Hair Loss After Surgery, Illness, or Major Life Events
Sometimes hair shedding follows a significant event that temporarily disrupts the normal hair-growth cycle.
This can include:
Surgery
Hospitalization
Severe infection
High fever
Major emotional stress
Significant dietary changes
This type of shedding may be temporary, but identifying the trigger can help determine what to expect and whether additional treatment is appropriate.
When Should You See a Hair Loss Specialist?
Not every episode of shedding requires treatment. However, it's worth considering an evaluation if you notice:
Rapid or sudden hair loss
A widening part
A receding hairline
A thinning crown
Bald patches
Persistent excessive shedding
Scalp inflammation or discomfort
Eyebrow or eyelash loss
Hair loss accompanied by other unexplained symptoms
The earlier the cause is identified, the more treatment options may be available.
How Is Hair Loss Diagnosed?
There isn't one treatment that works for every type of hair loss.
During a hair loss evaluation, your provider may consider:
Your hair-loss pattern
Where are you losing density, and how quickly is it happening?
Your medical history
Recent illness, surgery, pregnancy, menopause, stress, medications, and other health changes can provide important clues.
Family history
Genetic hair loss frequently runs in families.
Scalp examination
Examining the scalp and follicles can help distinguish different forms of hair loss.
Laboratory testing
Depending on your symptoms and history, your provider may recommend blood tests to investigate potential contributors such as nutritional or hormonal abnormalities.
Hair Loss Treatment Options
Treatment depends on why you're losing hair.
Depending on your diagnosis and individual goals, treatment options may include:
Minoxidil
Topical or oral minoxidil may be appropriate for certain types of hair loss. Your provider can discuss whether it is suitable for you.
Spironolactone
For some women with hormone-related hair loss, spironolactone may be prescribed off-label to help reduce androgen activity.
PRP Hair Restoration
Platelet-rich plasma (PRP) therapy uses a patient's own blood-derived platelets and growth factors as part of a treatment approach for certain types of hair thinning.
Hair Transplantation
For appropriate candidates with sufficient donor hair, FUE or FUT hair transplantation can redistribute existing follicles to areas of thinning or hair loss.
Combination Treatment
In some cases, combining therapies may provide a more comprehensive approach to hair restoration.
The goal isn't simply to treat the symptom. It's to understand the cause, pattern, and progression of your hair loss before deciding on treatment.

Frequently Asked Questions About Hair Loss
What is the most common cause of hair loss?
Hereditary hair loss, or androgenetic alopecia, is one of the most common causes of hair loss in both men and women. However, many other conditions can cause shedding or thinning.
Is hair loss always permanent?
No. Some forms of hair shedding, including certain cases of telogen effluvium, can improve after the underlying trigger is addressed. Other forms, such as hereditary hair loss, tend to be progressive without treatment.
Can stress cause hair loss?
Yes. Significant physical or emotional stress can trigger telogen effluvium, a temporary form of increased shedding.
Can women get hair transplants?
Yes. Some women may be good candidates for hair transplantation. Candidacy depends on the cause of hair loss, donor hair availability, pattern of thinning, and individual goals.
Can vitamins stop hair loss?
Vitamins can help when a genuine nutritional deficiency is contributing to hair loss. However, supplements are unlikely to correct every type of hair loss, particularly genetically driven hair loss.
What should I do if my hair is suddenly falling out?
Sudden or unusual hair loss deserves evaluation, particularly if it occurs with bald patches, scalp symptoms, or other changes in your health. Identifying the underlying cause is the first step toward choosing an appropriate treatment.
