Why are Men more Prone to Hair Loss?

Hair loss is a common phenomenon that affects people of all genders and ages. However, when it comes to hair loss, men often take the spotlight. It is estimated that approximately two-thirds of men experience some degree of hair loss by the age of 35. While women also face hair loss challenges, the prevalence and pattern of hair loss in men differ significantly. In this comprehensive article, we will delve deeper into the various biological, genetic, hormonal, and environmental factors that contribute to why men are more prone to hair loss than women.

I. Hormonal Factors:

The Role of Androgens: Androgens, a group of male sex hormones, play a crucial role in male hair loss. Testosterone, the primary androgen, is converted into dihydrotestosterone (DHT) by the enzyme 5-alpha reductase. DHT, in genetically susceptible individuals, binds to receptors in the hair follicles, leading to a process called miniaturization. This results in thinner and shorter hairs until the follicles eventually cease producing visible hair.

Genetic Susceptibility: Male pattern baldness, or androgenetic alopecia, is the most common form of hair loss in men. It is strongly influenced by genetics and tends to run in families. Several genes have been identified as potential contributors to male pattern baldness, including those involved in hormone regulation, hair follicle development, and immune response.

II. Structural and Biological Differences:

Hair Follicle Sensitivity: Hair follicles in men are more sensitive to the effects of DHT than those in women. This increased sensitivity stems from the presence of androgen receptors in the scalp follicles, which triggers a cascade of events leading to hair follicle miniaturization and eventual dormancy.

Hair Follicle Distribution: The distribution of hair follicles on the scalp also contributes to the differing patterns of hair loss between men and women. Men tend to lose hair in a characteristic pattern known as the Norwood-Hamilton scale, which includes a receding hairline and thinning crown. This pattern is a reflection of the androgen-sensitive follicles located in specific regions of the scalp.

III. Genetic Factors:

Polygenic Inheritance: Male pattern baldness is considered a polygenic trait, meaning it is influenced by multiple genes rather than a single gene. Various studies have identified potential genetic markers associated with male pattern baldness, highlighting the complexity of its inheritance.

X-Chromosome Inactivation: Another genetic factor that contributes to the discrepancy in hair loss between men and women is the presence of two X chromosomes in women. Women have the ability to compensate for genes related to hair loss through a process called X-chromosome inactivation, which renders one of the X chromosomes in each cell genetically silent. This phenomenon provides some level of protection against hair loss for women.

IV. Environmental and Lifestyle Factors:

Hairstyling Practices: Certain hairstyles that exert excessive tension or traction on the hair, such as tight ponytails, braids, or man buns, can contribute to a condition called traction alopecia. This type of hair loss is more commonly observed in women but can affect men who engage in similar styling practices.

Smoking and Poor Nutrition: Lifestyle choices can impact overall hair health. Smoking has been associated with increased hair loss due to reduced blood flow to the hair follicles, while a poor diet lacking essential nutrients can deprive the hair of the nourishment it needs to thrive.


While hair loss can be a distressing experience for men, understanding the complex interplay of hormonal, genetic, structural, and environmental factors can shed light on why men are more prone to hair loss than women. By unraveling these factors, individuals can make informed decisions about treatment options, explore preventive measures, and adopt lifestyle modifications that promote optimal hair health. It is important to note that seeking professional guidance from dermatologists or hair loss specialists is essential for accurate diagnosis, personalized treatment plans, and ongoing support. Remember, hair loss does not define one’s worth or masculinity, and embracing one’s individuality and self-confidence can greatly enhance the journey of coping with hair loss.
