AGA (Androgenetic Alopecia): Causes, Symptoms, and Treatments for Hair Loss in Japan

by Business Vocal Executive Editor

Hair is often associated with beauty, confidence, and health. For both men and women, having a full head of hair is seen as a symbol of youth and vitality. When hair begins to thin or fall out, it can have significant emotional and psychological effects. People may feel less confident, which can negatively impact their social and professional lives.

Unfortunately, a high percentage of the male population in Asia, especially in Japan, suffers from hair loss due to Androgenetic Alopecia (AGA). Recent studies show that around 30% of men in Japan experience some form of hair loss by the time they reach 30, and the numbers continue to rise with age. By the age of 50, over 50% of men are affected by AGA. This trend is not only a cosmetic issue but also a growing concern in terms of self-esteem and well-being.

Background and Studies on Androgenetic Alopecia (AGA) 

The first scientific discussions surrounding Androgenetic Alopecia (AGA) date back to the early 20th century. The condition was initially studied by various researchers, but Dr. James Hamilton, an American dermatologist, is widely credited for laying the foundation of understanding AGA in men. In the 1940s, Dr. Hamilton conducted studies on the relationship between testosterone and hair loss, identifying dihydrotestosterone (DHT) as a key hormone involved in the development of male-pattern baldness.

Following Dr. Hamilton’s work, Dr. Thomas B. Dietrich, a prominent researcher in the 1950s, contributed to understanding the role of genetics in AGA. His studies confirmed that both genetic and hormonal factors contribute to hair loss, emphasizing the importance of DHT in shrinking hair follicles over time.

These studies marked the beginning of the modern understanding of AGA, which was later expanded upon by researchers worldwide, including those in Japan. Today, we know that AGA is influenced by both genetic predispositions and hormonal imbalances, with DHT being the primary culprit behind the shrinking of hair follicles.

What is AGA? Understanding the Medical Terms

Androgenetic Alopecia (AGA) is a hereditary condition that causes progressive hair loss, primarily on the scalp. It is driven by genetic sensitivity to dihydrotestosterone (DHT), a hormone produced from testosterone. DHT binds to receptors in hair follicles, shrinking them over time and reducing hair growth.

In men, AGA typically begins with a receding hairline and bald spots on the crown of the head. In women, AGA causes diffuse thinning across the scalp, usually without complete baldness. While it is more prevalent in men, women can also experience AGA, especially as they age or undergo hormonal changes such as during menopause.

Symptoms of Androgenetic Alopecia

Well as a problem that is generally attributed to genetics, it is quite important to understand that it the symptoms are not exactly the same in every individual. The most common symptoms of AGA include:

  • Receding hairline: In men, this often starts at the temples or forehead.
  • Thinning crown: A noticeable decrease in hair density at the top or crown of the head.
  • Diffuse thinning: In women, thinning occurs more evenly across the scalp, particularly at the crown.
  • Miniaturization of hair follicles: Over time, hair grows thinner, shorter, and less pigmented.

As the condition progresses, hair loss becomes more apparent and can affect a person’s self-image. Many people seek early intervention when they notice these symptoms to prevent further thinning.

Types of Treatments for AGA

There are several treatment options available for managing AGA. The most common include:

  • Minoxidil: An over-the-counter topical treatment that helps stimulate hair growth and slow down hair loss.
  • Finasteride: A prescription medication that blocks the formation of DHT, the hormone responsible for shrinking hair follicles.
  • Hair Transplants: A surgical procedure where hair follicles from areas with healthy hair are transplanted to balding areas.
  • Platelet-Rich Plasma (PRP) Therapy: A non-surgical treatment that involves injecting concentrated platelets into the scalp to promote hair regrowth.
  • Low-Level Laser Therapy (LLLT): A non-invasive treatment that uses light to stimulate hair follicles and promote growth.

These treatments may not cure AGA but can significantly slow its progression and restore some of the lost hair. It’s important to consult with a professional to determine the best course of action based on individual needs.

The Role of Professional Help in Finding a Clear Solution

While there are many over-the-counter and home treatments available, seeking professional medical help is crucial for determining the right approach. A dermatologist or a specialist in hair restoration can provide a diagnosis and recommend a personalized treatment plan tailored to the individual’s unique situation.

Professional consultations also offer access to advanced treatments like hair transplants or prescription medications, which are often more effective than over-the-counter solutions. These experts can also help manage expectations and ensure that patients understand the realistic outcomes of their chosen treatments.
