Androgenetic alopecia is hereditary hair loss driven by follicle sensitivity to DHT, affecting 80–90% of men to some degree and a significant share of women, most often after menopause. Hair transplantation is currently the only method that restores hair to areas where follicles have stopped producing it; finasteride, minoxidil, and PRP can slow progression but do not permanently reverse it.

# Androgenetic Alopecia (Male Pattern Hair Loss)

## What Is Androgenetic Alopecia?

Androgenetic alopecia is a hereditary hair loss condition caused by genetic sensitivity of hair follicles to dihydrotestosterone (DHT). Affected follicles progressively miniaturize, producing thinner and shorter hairs until growth stops. It affects approximately 80–90% of men to varying degrees and a large proportion of women later in life.

- Also known as: male pattern hair loss (men), female pattern hair loss (women)

## How Does Androgenetic Alopecia Affect Men?

Male pattern hair loss usually begins between the late teens and early forties. It follows a recognizable sequence: recession at the temples, thinning at the crown (vertex), then merging of the frontal and crown areas. Progression is slow and often cyclical, with periods of heavier shedding followed by relative stability.

- Pattern stages: temple recession → crown thinning → frontal-crown merge

## What Causes Androgenetic Alopecia In Men?

The main drivers are genetic predisposition, follicle sensitivity to DHT, and age-related changes in the hair growth cycle. DHT shortens the anagen (growth) phase, so each cycle produces progressively weaker hairs until the follicle stops functioning.

- Key factors: genetics, DHT sensitivity, growth-cycle aging

## What Are The Symptoms In Men?

Symptoms develop gradually rather than in sudden patches: a receding frontal hairline, increased scalp visibility at the crown, and an overall drop in hair density. Complete baldness can take many years to develop and depends on individual genetics.

- Visible signs: receding hairline, crown thinning, reduced density

## How Does Androgenetic Alopecia Affect Women?

In women, the condition is called female pattern hair loss. It presents as diffuse thinning on the crown and widening of the central part, while the frontal hairline is usually preserved. Complete baldness in women is rare.

- Pattern: crown thinning, wider part, hairline preserved

## What Causes Androgenetic Alopecia In Women?

Female pattern hair loss stems from genetic predisposition, age-related hormonal changes, and increased follicle sensitivity to normal androgen levels. Unlike men, women often do not have elevated androgens; their follicles simply react more strongly to typical hormone levels.

- Key factors: genetics, hormonal aging, follicle sensitivity

## What Are The Symptoms In Women?

Hair thinning in women progresses slowly and evenly, with individual strands becoming finer and overall volume dropping rather than forming distinct bald patches. The change often becomes more noticeable after menopause but can start earlier in genetically predisposed women.

- Onset marker: often more visible after menopause

## How Is Androgenetic Alopecia Treated?

Treatment aims to slow progression and preserve existing hair, since regrowth of fully inactive follicles requires surgery. Non-surgical options include prescribed topical or oral medications, PRP therapy, and scalp-focused treatments; these delay thinning but do not permanently restore lost hair. Hair transplantation is the only method that restores hair to areas where follicles are no longer active, transferring healthy follicles from donor areas to thinning or bald regions.

- Methods: finasteride/minoxidil, ketoconazole shampoo, PRP, hair transplantation

## What Is The Long-Term Outlook?

Androgenetic alopecia is progressive. Early diagnosis preserves more existing hair and keeps more treatment options open. Management should be individualized and guided by qualified medical professionals.

## Frequently Asked Questions

### How to stop androgenetic alopecia?

Starting finasteride and minoxidil early is the standard approach to slow progression. Ketoconazole shampoo and hair transplantation are additional options depending on the stage.

### What is Stage 4 male pattern baldness?

Stage IV involves deeper temple recession combined with crown thinning, while a bridge of hair still connects the two areas.

### What triggers androgenic alopecia?

Genetic sensitivity of hair follicles to DHT triggers the condition, causing progressive follicle miniaturization and thinning over successive growth cycles.

### Can male androgenetic alopecia be reversed?

Finasteride and minoxidil can produce partial regrowth, but full reversal of established hair loss is uncommon without a hair transplant.

### Will I go completely bald with androgenetic alopecia?

No. Many men do not go completely bald, particularly when treatment starts early in the progression.
