Men’s Hair Loss: Symptoms and Causes

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Male pattern baldness is a common condition characterized by a receding hairline, thinning at the crown, and overall hair thinning. The primary cause is androgenetic alopecia, a hereditary condition influenced by the hormone DHT. Understanding these symptoms and causes is crucial for effective treatment and management of hair loss in men.

Symptoms of Men’s Hair Loss

Men’s hair loss, commonly referred to as male pattern baldness or androgenetic alopecia (AGA), is characterized by a distinct pattern of hair thinning and loss. The primary symptoms include:

• Receding Hairline: One of the earliest signs of male pattern baldness is a receding hairline, often forming an “M” shape as the hair thins at the temples.
• Thinning at the Crown: Another common symptom is thinning at the crown of the head, which can eventually lead to a bald spot.
• Overall Thinning: Some men experience a more diffuse thinning across the entire scalp, rather than in specific areas.

These symptoms are progressive and can lead to significant hair loss over time if not treated1 2.

Causes of Men’s Hair Loss

The primary cause of male pattern baldness is androgenetic alopecia, a hereditary condition influenced by androgens, particularly dihydrotestosterone (DHT). The key factors include:

• Genetics: AGA is a hereditary disorder, meaning it is passed down from one’s parents. It follows a specific pattern causing progressive thinning of hair in both men and women2.
• Dihydrotestosterone (DHT): DHT, a derivative of testosterone, plays a crucial role in hair loss. It binds to receptors in hair follicles, leading to their miniaturization and eventual loss. Elevated levels of DHT in the scalp are a significant contributing factor to male pattern baldness1 3.
• Hormonal Changes: Changes in hormone levels, particularly an increase in DHT, can trigger and accelerate hair loss. Treatments that inhibit the conversion of testosterone to DHT, such as finasteride and dutasteride, have been shown to be effective in slowing hair loss and promoting hair regrowth1 3.
