Understanding Androgenetic Alopecia: The Science Behind Male and Female Pattern Baldness

Washington, OH


Hair loss is a common concern that affects millions of people worldwide, impacting not only physical appearance but also emotional well-being. One of the most prevalent forms of hair loss is androgenetic alopecia (AGA), commonly known as male and female pattern baldness. In this blog, we will delve into the science behind androgenetic alopecia, exploring its causes, symptoms, and potential treatment options.

Defining Androgenetic Alopecia:

Androgenetic alopecia is a hereditary condition characterized by a gradual and predictable pattern of hair loss. It affects both men and women, although the presentation differs between the sexes. In men, it typically results in a receding hairline and balding at the crown, while women may experience diffuse thinning across the scalp.


The primary culprits behind androgenetic alopecia are hormones and genetics. The condition is linked to the hormone dihydrotestosterone (DHT), a derivative of testosterone. In individuals genetically predisposed to AGA, hair follicles on the scalp are sensitive to DHT. Over time, exposure to DHT causes the hair follicles to shrink and produce finer, shorter hairs. Eventually, these follicles may cease to produce hair altogether.

Genetic Factors:

Family history plays a crucial role in androgenetic alopecia. If your parents or grandparents experienced pattern baldness, you are more likely to develop it yourself. The inheritance of specific genes contributes to the sensitivity of hair follicles to DHT, making some individuals more susceptible to AGA than others.


The symptoms of androgenetic alopecia differ between men and women. In men, hair loss often begins at the temples and crown, forming an M-shaped pattern. Women, on the other hand, may experience diffuse thinning across the entire scalp, with the hairline remaining intact.


Diagnosing androgenetic alopecia typically involves a thorough medical history and examination of the scalp. In some cases, a dermatologist may perform additional tests to rule out other potential causes of hair loss, such as nutritional deficiencies or hormonal imbalances.

Treatment Options:

While there is no cure for androgenetic alopecia, several treatment options aim to slow down hair loss and promote hair regrowth. Common approaches include:

  1. Topical Medications: Minoxidil is a topical medication that is FDA-approved for treating androgenetic alopecia. It is available over-the-counter and can be applied directly to the scalp.
  2. Oral Medications: Finasteride, an oral medication, is FDA-approved for treating male pattern baldness. It works by inhibiting the conversion of testosterone into DHT, thereby reducing the impact of DHT on hair follicles.
  3. Low-Level Laser Therapy: This non-invasive treatment involves the use of low-level lasers or light-emitting diodes to stimulate hair follicles and promote hair growth.
  4. Hair Transplant Surgery: For those seeking a more permanent solution, hair transplant surgery involves transplanting hair follicles from donor areas to areas experiencing hair loss.
  5. Alma TED (trans epidermal delivery): A pain free, needle-free treatment option that stimulates the hair follicle and delivers serum to improve health, length, and thickness of the follicles.


Androgenetic alopecia is a common and often distressing condition that affects both men and women. Understanding the underlying causes and available treatment options is crucial for those dealing with pattern baldness. While there is no one-size-fits-all solution, consulting with a healthcare professional or dermatologist can help individuals develop a personalized approach to managing androgenetic alopecia and preserving their hair health.
