Stages of Male pattern baldness, causes and Treatment

Male pattern baldness, also known as androgenetic alopecia, is a common condition affecting millions of men worldwide. It is characterized by a receding hairline and thinning of hair on the crown of the head. While the condition is generally considered to be a natural part of aging, it can have a significant impact on a man’s self-esteem and confidence.

Causes of Male Pattern Baldness

Male pattern baldness is primarily caused by genetics and hormonal changes in the body. It is believed to be related to the hormone dihydrotestosterone (DHT), which is a byproduct of testosterone. DHT binds to hair follicles and causes them to shrink, resulting in shorter and finer hair. Over time, this process can lead to hair loss and baldness.

In addition to genetics and hormonal changes, other factors may contribute to male pattern baldness. These include:

  1. Age: As men age, their hair follicles become less active, resulting in thinner and finer hair.
  2. Stress: High levels of stress can cause hair loss, although the exact mechanism is not fully understood.
  3. Poor nutrition: A diet that is low in nutrients, particularly vitamins, and minerals that are important for hair health, may contribute to hair loss.
  4. Medications: Certain medications, such as chemotherapy drugs and blood thinners, may cause hair loss as a side effect.

Hormonal Influence: DHT and Hair Follicle Miniaturization

DHT, a byproduct of testosterone, is present in higher levels in individuals with male pattern baldness. When DHT interacts with genetically susceptible hair follicles, it causes a process known as miniaturization. Miniaturization refers to the progressive shrinking of hair follicles over time, leading to shorter, finer, and less pigmented hair strands. Eventually, the affected hair follicles cease to produce visible hair, resulting in baldness.

Norwood-Hamilton Scale: Stages of Male Pattern Baldness

The Norwood-Hamilton scale is commonly used to classify the progression of male pattern baldness. It consists of seven stages, ranging from minimal hair loss at Stage 1 to extensive baldness at Stage 7. Understanding the stages helps individuals assess the severity of their hair loss and determine suitable treatment options.

Stage 1: No Significant Hair Loss

Stage 1 on the Norwood-Hamilton Scale represents minimal to no hair loss. The hairline is intact and positioned slightly above the temples, forming a straight line across the forehead. At this stage, there may be no noticeable signs of hair loss or recession.

Stage 2: Minimal Hairline Recession

In Stage 2, there is a slight recession of the hairline around the temples. The hairline may move slightly higher and develop a slight “M” shape. Despite the mild recession, the overall appearance of hair loss is still minimal.

Stage 3: Noticeable Hairline Recession

Stage 3 marks a more noticeable recession of the hairline, forming a deeper “M” shape. The temporal areas show significant hair loss, and the hairline may recede further backward. However, there is usually still a considerable amount of hair present on the crown area.

Stage 4: Advanced Hairline Recession and Crown Thinning

At Stage 4, there is significant hair loss both in the frontal hairline and the crown area. The hairline recession is more prominent, and the crown shows visible thinning or balding. The remaining hair separating the two areas becomes narrower.

Stage 5: Extensive Hair Loss on Top

In Stage 5, the hair loss becomes more pronounced. The area of baldness on the crown becomes larger, and the remaining hair separating the frontal hairline and crown is narrower. The two areas of hair loss may be more clearly defined.

Stage 6: Severe Hair Loss with Limited Separation

At Stage 6, there is a significant amount of hair loss on the top of the head, with minimal to no separation between the frontal hairline and crown areas. The remaining hair may form a thin bridge or show sparse coverage.

Stage 7: Extensive Hair Loss with Only a Rim of Hair Remaining

Stage 7 represents the most advanced stage of male pattern baldness. Only a rim of hair remains on the sides and back of the scalp, known as the “horseshoe” pattern. The hair loss is extensive, leaving the top of the head almost completely bald.

Treatment Options for Male Pattern Baldness

While there is no cure for male pattern baldness, there are several treatment options available that can help slow down or even reverse hair loss. These include:

  1. Medications: There are several medications that can be used to treat male pattern baldness, including finasteride and minoxidil. Finasteride is a prescription medication that works by blocking the production of DHT, which can help slow down hair loss and even promote hair growth in some cases. Minoxidil is a topical medication that is applied to the scalp and works by increasing blood flow to the hair follicles, which can help promote hair growth.
  2. Hair transplant: A hair transplant is a surgical procedure that involves transplanting hair follicles from one area of the scalp to another. This can be an effective treatment option for men with advanced hair loss.
  3. Laser therapy: Low-level laser therapy is a non-invasive treatment option that involves using light energy to stimulate hair follicles. This can help promote hair growth and reduce hair loss.
  4. Scalp micro pigmentation: Scalp micro pigmentation is a non-surgical procedure that involves tattooing tiny dots onto the scalp to create the illusion of hair follicles. This can be an effective treatment option for men who are not good candidates for hair transplant surgery.
  5. Hairpieces and wigs: Hairpieces and wigs can be an effective temporary solution for men with hair loss. They can be customized to match the color and texture of the natural hair and can be removed and reattached as needed.

Prevention of Male Pattern Baldness

Some of the most effective strategies for preventing male pattern baldness.

  1. Maintain a healthy diet:

A healthy, well-balanced diet is important for overall health, including the health of your hair. Eating a diet that is rich in vitamins, minerals, and protein can help keep your hair strong and healthy. Foods that are particularly beneficial for hair health include leafy greens, fatty fish, nuts, and eggs.

  1. Manage stress:

Stress is a common trigger for hair loss, and chronic stress can lead to a condition known as telogen effluvium, which causes hair to enter the resting phase of the hair growth cycle and fall out prematurely. Practicing stress-management techniques, such as meditation, yoga, or deep breathing, can help reduce stress levels and minimize the risk of hair loss.

  1. Use hair care products wisely:

Harsh chemicals and styling products can damage hair and contribute to hair loss. Avoid using products that contain sulfates, parabens, and alcohol, as these can dry out the scalp and damage hair follicles. Instead, choose natural, organic hair care products that are gentle on the scalp.

  1. Quit smoking:

Smoking has been linked to an increased risk of hair loss, as it can damage hair follicles and restrict blood flow to the scalp. Quitting smoking can improve blood flow to the scalp and help prevent hair loss.

  1. Treat underlying medical conditions:

Certain medical conditions, such as thyroid disorders, can contribute to hair loss. If you are experiencing hair loss, it is important to talk to your healthcare provider to rule out any underlying medical conditions that may be contributing to the problem.

  1. Consider medication:

There are several medications available that can help prevent hair loss and promote hair growth. Finasteride and minoxidil are two of the most commonly prescribed medications for male pattern baldness. Finasteride works by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone that contributes to hair loss. Minoxidil, on the other hand, works by increasing blood flow to the scalp and promoting hair growth.

  1. Hair transplant surgery:

For men with more advanced hair loss, hair transplant surgery may be an option. During this procedure, hair follicles are taken from areas of the scalp where hair is still growing and transplanted to areas where hair has been lost. This can be a highly effective way to restore hair growth and improve the appearance of the scalp.


Male pattern baldness, characterized by a progressive loss of hair on the scalp, is a common condition that affects many men. Understanding its causes, effects, and available treatment options is essential for individuals dealing with hair loss. While there is no cure for male pattern baldness, various treatments, including medications, hair transplantation, low-level laser therapy, and cosmetic techniques, can help manage the condition and promote hair growth. Additionally, maintaining a healthy lifestyle and adopting good hair care practices can support overall hair health. By seeking professional guidance and making informed choices, individuals can address the challenges associated with male pattern baldness and regain confidence in their appearance.
