What Age Does Hair Loss Stop In Men?

Quick Summary: When Does Hair Loss Stop in Men?

Key takeaway: According to studies, up to 30-50% of men will experience some form of male pattern baldness by the age of 50. Hair loss tends to stabilise between the ages of 30 and 50.

The American Hair Loss Association states that the vast majority of these cases (95%) are due to androgenic alopecia. The factors are influence hair loss in men include genetics, age, and hormonal changes[1] . It often results in recession to the hairline, temples and thinning to the crown.

So, what age does hair loss stop in men?

Many reports state that hair loss can potentially stabilise between the ages of 30 and 50. However, many men will experience continuous hair thinning even when they get past the age of 45. [2]

Read on to learn everything about hair loss in men, including when it starts and stops, as well as some measures that could actually help you stop hair loss.

Understanding the Hair Growth Cycle

Hair growth is a dynamic process that progresses through three main stages. These stages are absolutely fundamental to maintaining hair health and volume. [3]

Here’s a quick overview of these three stages:

1. Anagen (Growth Phase) – This is the most active stage where hair grows approximately 1 cm per month. This phase lasts between 2 and 7 years and is subject to genetic factors.
2. Catagen (Transitional Phase) – A short phase that only lasts two weeks. During this phase, hair detaches from its blood supply, which stops hair growth.
3. Telogen (Resting Phase) – Approximately 10-15% of scalp hair is in this dormant phase at any time. The telogen phase lasts about 3 months before the hair sheds and the cycle renews.

The first step to fully understand hair loss in men and whether it stops with age is to understand these three cycles.

When Does Hair Loss Start in Men?

Most men experience some degree of hair loss with age and it often starts in their 20s. However, the onset and severity vary greatly between individuals. The table below provides a detailed overview of when and how hair loss starts in different age groups.

Does Hair Loss Stop? Understanding Stabilisation in Men

Hair loss may stabilise for some men after an initial period of rapid loss. In general, this occurs around their late 30s or 40s, especially in those with milder genetic predispositions. However, men with strong genetic markers for hair loss will most likely continue to lose hair at a slower rate as they age.

The factors that determine at what age hair loss stops in men include:

• Genetics – Men with significant genetic predispositions tend to experience more rapid and prolonged hair loss. [4]
• Hormonal influence – High levels of DHT cause hair follicles to shrink over time. Hormonal shifts that occur later in life may reduce DHT’s impact on the scalp. [5]
• Lifestyle factors – Healthy habits (e.g., diet, exercise, stress management) play an indispensable role in whether your hair loss will stop with age or not. [6]

Patterns and Stages of Male Pattern Baldness

Male pattern baldness progresses in a characteristic pattern that’s defined by the Hamilton-Norwood scale. The scale classifies the stages of hair loss from minimal recession to severe baldness based on where thinning begins and how it advances. [7]

The table below details each stage and what to expect:

Some of the factors that influence the severity of hair loss include:

Scientists identified numerous factors that contribute to the pattern, severity, and timing of hair loss. If you understand these factors, you’ll be able to intervene and slow down the progress of hair loss. However, some of these factors are unmodifiable (i.e., there is nothing you can do to change them).

• Genetics and Heredity – Male pattern baldness (MPB) is hereditary and accounts for about 95% of male hair loss cases. A strong family history of early hair loss increases risk.
• Age-Related Changes – Hair follicles become increasingly sensitive to DHT as men age. This results in more gradual follicle miniaturisation, albeit some men experience stabilisation with time.
• Hormonal Factors – DHT plays a vital role in hair thinning and follicle shrinkage. Men with naturally high levels of DHT or testosterone may experience faster hair loss.
• Health Conditions – Medical issues (e.g., hypothyroidism, anaemia, certain autoimmune disorders) can cause temporary or permanent hair loss. [8]
• Medications – Hair loss is a common side effect of chemotherapy drugs, antidepressants, beta-blockers, and certain blood pressure medications. [9]
• Lifestyle Factors – Poor diet, stress, smoking, and inadequate sleep can negatively impact follicle health, which accelerates hair loss for individuals with a genetic predisposition.

Available Treatments to Slow or Reverse Hair Loss

There are numerous treatments on the market to aid men with hair loss. The effectiveness of these treatments varies greatly from one individual to another. Additionally, other factors such as hair loss stage, age of the patient, and their health status all play a role in this matter.

Let’s go over the most common treatment options for male pattern hair baldness:

Pharmacological Drugs- Minoxidil and Finasteride

Minoxidil is a treatment for hair loss that’s approved by the U.S. Food and Drug Administration (FDA). The topical form of the treatment is available over the counter to stimulate hair growth and stop hair thinning. [10]

The second pharmacological treatment is finasteride, which reduces DHT levels and slows follicle shrinkage. [10]

Low-Level Laser Therapy (LLLT)

Laser therapy stimulates follicles and may improve hair density. However, the results of this therapy vary widely. [11]

Hair Transplantation

Follicular Unit Transplantation (FUT) and Follicular Unit Excision (FUE) are surgical options that relocate hair from dense areas to thinning spots. This is the preferred treatment option for many men who have experienced a receding hairline or balding crown.

Lifestyle Changes

Diet, scalp care, and stress management may support follicle health and delay hair loss progression.

Platelet-Rich Plasma

Platelet-rich plasma (PRP) and topical antiandrogens are newer treatments that produce promising results. For example, PRP uses growth factors from the patient’s blood to encourage regrowth. [12]

Conclusion

Hair loss is a common and progressive condition in men that stems from genetic, hormonal, and lifestyle factors. It often stops or slows between the ages of 30 and 50. Although male pattern baldness is inevitable for most individuals, lifestyle changes and medical treatments provide potential ways to stop hair loss.

Make sure to consult with your healthcare provider early on to prevent further hair loss with various intervention strategies (e.g., dietary choices, stress management, medical treatments).
