Androgenetic Alopecia (Pattern Baldness)

Androgenetic alopecia, often referred to as male or female pattern baldness, is a common form of hair loss that affects both men and women. It is the most common cause of hair loss, characterized by a gradual thinning of hair, typically starting at the temples or crown of the head. Here’s a detailed overview:


  • Hormones: Androgenetic alopecia is believed to be primarily driven by hormones called androgens, particularly dihydrotestosterone (DHT). DHT is a byproduct of testosterone, and individuals with androgenetic alopecia may have hair follicles that are more sensitive to DHT.
  • Genetics: Family history plays a significant role. If your parents or grandparents experienced pattern baldness, you are more likely to develop it.


  • Gradual Thinning: The most noticeable symptom is a gradual thinning of hair, usually starting at the temples or crown of the head.
  • Miniaturization: Hair follicles shrink over time, producing finer and shorter hairs.
  • Patterned Baldness: Men often develop a receding hairline, while women may experience widening of the part and overall thinning.


While androgenetic alopecia cannot be cured, several treatments can slow its progression or help regrow hair. These include:

  • Medications:
    • Minoxidil : Over-the-counter topical treatment that can be applied to the scalp. It helps to increase blood flow to the hair follicles and may stimulate hair growth.
    • Finasteride : Prescription medication for men that blocks the conversion of testosterone into DHT. It’s not FDA-approved for women due to potential risks during pregnancy.
  • Low-Level Laser Therapy (LLLT): Devices like laser combs or helmets can stimulate hair follicles and promote hair growth.
  • Platelet-Rich Plasma (PRP) Therapy: This involves injecting the patient’s own concentrated platelets into the scalp to promote hair growth.
  • Hair Transplant Surgery: In cases of advanced balding, hair transplant procedures can be effective. This involves moving hair follicles from areas of the scalp with healthy hair growth to areas of thinning or baldness.


While you can’t prevent androgenetic alopecia if it’s in your genetics, you can take steps to slow its progression:

  • Healthy Lifestyle: Eating a balanced diet, managing stress, and avoiding smoking can help.
  • Gentle Hair Care: Avoid harsh treatments, tight hairstyles, and excessive pulling or styling.
  • Early Treatment: Starting treatment early can be more effective in preserving and regrowing hair.

 It’s essential for individuals experiencing hair loss to consult with a dermatologist or hair loss specialist to determine the best course of action for their specific situation. Each person’s response to treatment can vary, so what works for one may not work for another.

  1. Psychological Impact: Hair loss, especially at a young age, can have a profound psychological impact. It can lead to decreased self-esteem, lack of confidence, and even depression or anxiety. Young people may feel less attractive or worry about how others perceive them.
  2. Social Effects: Balding at a young age can affect social interactions. Some individuals might withdraw from social activities, avoid dating, or feel self-conscious in public settings due to concerns about their appearance.
  3. Body Image: Young people experiencing androgenetic alopecia may struggle with their body image. Hair is often seen as an important part of physical attractiveness and losing it prematurely can lead to feelings of inadequacy or unattractiveness.
  4. Career Impact: In some professions, appearance can play a significant role. Young individuals with androgenetic alopecia may worry about how their hair loss affects their professional image. This can be particularly challenging for careers where youth and vitality are valued.
  5. Stress: The stress of dealing with hair loss at a young age can exacerbate the problem. Stress is known to contribute to hair loss, creating a vicious cycle for those already experiencing androgenetic alopecia.
  6. Treatment Challenges: Treatments for androgenetic alopecia can be less effective when the condition starts at a younger age. Hair loss prevention medications like finasteride and minoxidil are typically more effective when started early, so the delay in seeking treatment can impact the effectiveness.
  7. Family History Impact: Discovering hair loss at a young age might also bring attention to family history. Recognizing that it’s a genetic condition can lead to concerns about future generations and how they might be impacted.
  8. Misconceptions and Stigma: Hair loss is sometimes unfairly associated with aging, so young people experiencing androgenetic alopecia may face misconceptions or stigma from others who don’t understand why they’re losing hair at such a young age.

Genetic Basis of Androgenetic Alopecia:

Genes Involved: Androgenetic alopecia is believed to be influenced by several genes, particularly those involved in hair follicle sensitivity to dihydrotestosterone (DHT), a derivative of testosterone. Two main genes implicated are:

  • Androgen Receptor (AR) Gene: Variations in this gene can affect how sensitive hair follicles are to DHT.
  • 5-alpha reductase (SRD5A2) Gene: This gene is involved in the conversion of testosterone to DHT.

Inheritance Pattern: The inheritance pattern of androgenetic alopecia is complex and involves multiple genetic factors. It is considered a polygenic trait, meaning it is influenced by many different genes.

Role of Genetic Testing:

  • Predictive Testing: Genetic testing can provide information about an individual’s genetic predisposition to androgenetic alopecia. However, it’s important to note that the presence of these genetic variations does not guarantee someone will develop the condition.
  • Early Detection: Testing can be used for early detection in individuals who have a family history of the condition. This can help in taking preventive measures or starting treatments early to slow down the progression of hair loss.
  • Personalized Treatment: Genetic information can guide personalized treatment approaches. For example:
  • Knowing a person is more sensitive to DHT might suggest the use of medications that target DHT, such as finasteride.
  • Understanding the genetic profile could also help in the development of new treatments tailored to specific genetic variations.
