Why is my hair falling out and getting thinner?

Understanding hair loss

Hair loss causes in women can feel overwhelming, but understanding what’s happening beneath the surface helps you take control. Your hair grows in cycles—anagen (growth), catagen (transition), and telogen (resting). When a higher percentage of follicles enter the telogen phase, you notice more shedding and visible thinning. By recognizing your pattern of female hair thinning and the phases of hair regrowth, you’ll be better equipped to address the root issues.

Common hair loss factors

Hormonal changes

Fluctuations in hormones often trigger thinning hair. Estrogen and progesterone keep strands in the growth phase longer, so when levels drop, more hair shifts into shedding.

Thyroid imbalance

An underactive or overactive thyroid can disrupt your hair cycle. For more details, see medical causes of hair loss.

Pregnancy and menopause

Postpartum shedding and menopause both involve rapid hormone shifts that can lead to temporary or prolonged thinning.

Nutritional deficiencies

Your diet directly affects follicle health. Missing key nutrients can stall growth and accelerate shedding.

Iron deficiency

Low iron impairs oxygen delivery to follicles, causing diffuse thinning. Learn more at hair loss deficiency.

Biotin deficiency

Biotin supports keratin production. A lack of this B vitamin can weaken strands and slow regrowth. Consider hair thinning vitamins if you suspect a shortfall.

Medical conditions

Underlying illnesses may manifest first as hair loss. Identifying them early helps you treat both the root cause and the symptom.

Autoimmune hair loss

Conditions like alopecia areata make your body attack its own follicles. For an in-depth look, visit autoimmune hair loss.

Scalp infections

Fungal or bacterial infections irritate the scalp and disrupt growth. Keep an eye out for redness, itching, or flaking.

Lifestyle triggers

Daily habits can either support or harm your hair’s health. Spotting harmful patterns is key to halting further loss.

Stress and hair shedding

High stress levels push follicles into the telogen phase prematurely, leading to notable shedding weeks later.

Styling damage

Excessive heat, tight ponytails, and harsh chemicals create breakage and traction alopecia. Avoid these hair thinning mistakes to preserve strand strength.

Diagnosing your hair loss

When to see a doctor

If you’re losing more than 100 strands per day or notice patchy bald spots, book a consultation. Early diagnosis delivers better outcomes.

Tests and evaluations

Expect blood work to check thyroid function, iron levels, and hormone panels. Your dermatologist may perform a scalp biopsy or pull test to pinpoint the type of hair loss, as outlined in causes of thinning hair.
