Androgenic Alopecia (Pattern Hair Loss): Causes & Symptoms

Androgenic alopecia—commonly known as male pattern baldness (AGA) or female pattern hair loss (FPHL)—is a gradual, progressive type of hair thinning influenced by genetics, hormones, and lifestyle factors. It is the most common form of hair loss seen in both men and women.

What Causes Androgenic Alopecia?

1. Hormonal Factors:
   Elevated levels of androgens, particularly dihydrotestosterone (DHT), can cause hair follicles to shrink, resulting in thinner, weaker hair over time.
2. Genetics:
   A hereditary predisposition plays a key role. If hair loss runs in your family, you're more likely to experience pattern baldness.
3. Lifestyle Factors:
   Although hormones and genetics are primary contributors, lifestyle habits such as poor nutrition, unmanaged stress, and improper scalp care can worsen the condition.

Symptoms in Men:

• A receding hairline, often beginning at the temples
• Thinning at the crown of the scalp
• Development of an “M-shaped” hair loss pattern over time

Symptoms in Women:

• Diffuse thinning across the scalp, especially noticeable along the center parting
• Rarely leads to complete baldness
• A “Christmas tree” pattern (widening of the central part) is often observed

Understanding the early signs of androgenic alopecia can help in taking timely action to slow progression and explore available treatment options.
