Why Is My Hair Falling Out? 12 Common Causes of Hair Loss in Men and Women

Why Is My Hair Falling Out? 12 Common Causes of Hair Loss in Men and Women

Seeing extra hair in your brush, on your pillow, or in the shower can feel stressful. Many people in San Jose ask the same question: “Why is my hair falling out?”

Hair loss is very common. It can happen to men and women of all ages. Sometimes it happens slowly over time. Other times, it can happen suddenly.

The good news is that hair loss often has a cause that can be identified and treated. Here are 12 common reasons why your hair may be thinning or shedding.

1. Genetics

One of the biggest causes of hair loss is family history. This is called pattern hair loss.

For men, it often starts with:

• A receding hairline

• Thinning at the crown

• Bald spots

For women, it usually looks like:

• A wider hair part

• Overall thinning

• Less hair volume

Genetics can affect hair at almost any age.

2. Stress

Stress can affect your whole body, including your hair. Big life changes, emotional stress, or illness can push hair follicles into a resting stage.

This may cause:

• Sudden shedding

• Thin patches

• Hair loss a few months after stress

Busy lifestyles in San Jose can sometimes make stress-related hair loss more common.

3. Hormonal Changes

Hormones play a major role in healthy hair growth.

Hair loss can happen during:

• Pregnancy

• Menopause

• Thyroid problems

• Hormone imbalances

Women often notice thinning hair during major hormonal changes.

4. Poor Diet

Your hair needs vitamins and nutrients to grow strong.

Low levels of:

• Iron

• Protein

• Vitamin D

• Zinc

can lead to weak or thinning hair.

Crash diets and skipping meals may also trigger hair shedding.

5. Tight Hairstyles

Some hairstyles pull too hard on the hair roots. Over time, this can damage hair follicles.

Common examples include:

• Tight ponytails

• Braids

• Buns

• Hair extensions

This type of hair loss is called traction alopecia.

6. Heat and Chemical Damage

Frequent coloring, bleaching, straightening, or heat styling can weaken hair over time.

Signs of damage include:

• Breakage

• Dryness

• Thinning ends

• Fragile hair strands

Protecting your hair from excess heat can help reduce damage.

7. Medical Conditions

Some health conditions can cause hair loss.

These may include:

• Thyroid disease

• Autoimmune disorders

• Scalp infections

• Anemia

Hair loss is sometimes one of the first signs that something else is happening in the body.

8. Medications

Certain medications may lead to hair thinning or shedding.

Some common examples include:

• Blood pressure medicine

• Antidepressants

• Chemotherapy drugs

• Hormone medications

If hair loss starts after a new medication, speak with your doctor.

9. Aging

As we age, hair naturally changes.

Hair may:

• Grow slower

• Become thinner

• Lose volume

• Shed more easily

This happens to both men and women over time.

10. Scalp Conditions

A healthy scalp is important for healthy hair growth.

Conditions like:

• Dandruff

• Psoriasis

• Scalp inflammation

can affect hair follicles and lead to shedding.

An unhealthy scalp can make it harder for hair to grow properly.

11. Rapid Weight Loss

Losing a large amount of weight quickly can shock the body.

This can trigger temporary hair shedding because the body is under stress and missing important nutrients.

Hair often improves once the body recovers and nutrition becomes balanced again.

12. Poor Sleep and Lifestyle Habits

Lack of sleep, smoking, dehydration, and unhealthy habits can all affect hair health.

Your hair grows best when your body is healthy and balanced.

Simple lifestyle changes can sometimes improve hair growth over time.

When Should You Get Help?

It is normal to lose some hair every day. But you should pay attention if you notice:

• Sudden hair shedding

• Bald spots

• A widening hair part

• Thinning edges

• Scalp irritation

• Hair that feels much thinner than before

Early treatment can often help slow or improve hair loss.
