Hair loss occurs when the normal hair growth cycle is disrupted, causing excessive shedding or thinning. The average person loses 50-100 hairs daily, but excessive hair loss exceeds this amount. Causes range from genetic factors to medical conditions and lifestyle habits.
Each hair follicle cycles through three phases: anagen (growth), catagen (transition), and telogen (resting). A disruption in any phase can lead to hair loss. For example, stress or illness may push follicles into the telogen phase prematurely, causing temporary shedding.
The most common types of hair loss include:
| Type | Cause | Duration |
|---|---|---|
| Androgenetic alopecia | Genetics and hormones (DHT) | Progressive |
| Telogen effluvium | Stress, illness, or nutritional deficiencies | Temporary (3-6 months) |
| Alopecia areata | Autoimmune attack on hair follicles | Unpredictable |
Androgenetic alopecia, or pattern baldness, affects about 50% of men and women over age 50 (American Academy of Dermatology). Telogen effluvium is often reversible once the underlying cause is addressed.
Consult a healthcare provider if hair loss is sudden, patchy, or accompanied by other symptoms like scalp pain or itching. A dermatologist can diagnose the cause through blood tests, scalp biopsies, or medical history review. Treatment options vary depending on the diagnosis, including medications, lifestyle changes, or therapies like platelet-rich plasma (PRP).
I noticed my hair shedding increased after a stressful project at work. After ruling out medical conditions, my doctor suggested reducing stress and improving my diet. Within six months, my hair regrowth stabilized.
While genetics can't be changed, adopting healthy habits may reduce hair loss risk. Eat a balanced diet rich in proteins, vitamins, and minerals. Avoid tight hairstyles that pull on the hair and limit heat styling tools. Manage stress through exercise, meditation, or therapy.
If hair loss persists despite lifestyle changes, consult a specialist for personalized advice. Understanding the root cause is the first step toward effective treatment.
