Genetics and Hair Loss


Genetics and Hair Loss

Do you feel like you’re losing more hair than usual? Chances are, genetics may be the cause. In this blog post, we’ll explore how different genes can impact your hair loss and provide tips on managing it.


This blog will explore the genetic basis of androgenetic alopecia, commonly known as male or female pattern baldness. This condition can affect both men and women and is caused by genetic or hormonal influences. We will look at the symptoms and inheritance of this condition and the role of the X chromosome in causing hair loss. We will also examine other factors contributing to hair loss, such as hereditary influences, age, hormones, and stress. Finally, we will discuss how a DNA test can help you understand your genetic predisposition to hair loss.

What is Male Pattern Baldness?

Men and women alike are susceptible to male pattern baldness, commonly known as androgenic alopecia or androgenetic alopecia. The disorder is characterised by thinning the scalp’s hair and a receding hairline. It has been estimated that genetics account for 80% of male pattern baldness, making it one of the most heritable conditions. The X chromosome may also play a role in male pattern baldness, as it is linked to the production of certain hormones that can affect hair growth. Other factors, such as hormonal changes, stress, and age, can also contribute to hair loss, but genetics are thought to be the primary cause. Understanding your DNA test results can help you determine if you are at an increased risk of developing male pattern baldness.

The Genetics of Male Pattern Baldness

The Genetics of Male Pattern Baldness is essential when looking at hair loss. Studies have shown that male pattern baldness (MPB) is highly heritable and is primarily attributed to genetics, with estimates of up to 80% of cases being attributed to genetic factors. Research has also demonstrated that the X chromosome plays a role in MPB, with some genetic variants found exclusively on the X chromosome-linked to a higher risk of MPB. In addition, environmental factors like hormonal changes and stress levels may also influence hair loss. By understanding the genetic components of MPB, individuals can gain insight into their likelihood of developing hair loss and take necessary steps to reduce their risk.

The Role of the X Chromosome

The X chromosome significantly influences the most prevalent kind of hair loss, male pattern baldness. Studies have found that the androgen receptor, a gene responsible for hair loss, is located on the X chromosome. Although this means that male pattern baldness can be inherited from either parent, it is more likely to be passed down through the mother. This means that the father’s genetic traits are not always a significant factor in determining how much hair loss an individual will experience. However, Genetics play an important role in hair loss, regardless of gender. For those looking to understand their own risk for hair loss better, a DNA test may help provide insight into their genetic predispositions.

Other Factors That Lead to Hair Loss

While genetics is the most common cause of hair loss, other factors can also lead to hair loss. These include medication, stress, and hormonal changes. Medicine may cause temporary hair loss or permanent baldness, depending on the type of drug and how long it is taken. Stress can also cause hair loss due to its effect on hormones, causing a condition known as telogen effluvium. Hormonal changes in both men and women can cause hair loss due to the increased hormone dihydrotestosterone (DHT). This hormone can shrink hair follicles, leading to baldness. Understanding the causes of your hair loss is critical to seeking appropriate treatment or lifestyle changes that could help reduce further hair loss.

Hereditary Hair Loss

The length of time that hair remains on the head may gradually shorten due to hereditary hair loss, commonly known as male pattern baldness or androgenetic alopecia. It is the most frequent reason for hair loss and is typically brought on by genetics, hormonal imbalances, and additional elements like stress and medicine. Genetic variations with a minor allele frequency of at least 1% have been found to account for 47.3% of hereditary-pattern baldness cases. Those genetically predisposed to this condition should pay special attention to their lifestyle and habits, which can lead to further hair loss. Eating a healthy diet and minimising stress can help reduce the progression of hereditary-pattern baldness for those predisposed to it.

Hair Loss and Age

Any age can experience hair loss, and as people age, the likelihood that they will experience symptoms rises. A 25% risk of some balding is present by age 30, and 50% of men have at least some discernible hair loss by age 50. About two-thirds of males begin to exhibit male-pattern baldness by the age of 60. Androgenetic alopecia is another common form of hair loss in both men and women, with its prevalence increasing with age. This type of hair loss is especially prominent in males and is known as male-pattern baldness. Genetics plays a vital role in hereditary hair loss, with the X chromosome playing a significant part in the development of this condition. Besides genetics, other factors such as medication, stress, and hormonal changes can also contribute to hair loss. Understanding these factors can help one take proactive steps to prevent or minimise further hair loss.

Understanding Your DNA Test

Understanding your DNA test is essential when considering hair loss. A DNA test can help identify the genetic markers associated with male pattern baldness and uncover any hereditary predisposition to thinning hair. These tests look for variations in specific genes, such as those located on the X chromosome, which is thought to be closely linked to the development of male pattern baldness. A DNA test can also uncover other factors contributing to hair loss, such as hormonal changes or age-related thinning. By understanding how genetics can affect hair loss, you can take steps to maximise your hair growth potential and slow down the progression of baldness.

Hormonal Changes and Hair Loss

Hormones can play a significant role in hair loss, especially for those with hereditary conditions such as androgenic alopecia. Falling estrogen levels can lead to temporary hair loss after giving birth, while PCOS is a hormonal imbalance that can cause hair shedding. In addition, Estradiol can significantly alter hair follicle growth and cycle by binding to the metabolism of locally expressed high-affinity estrogen receptors. Finally, hormones are not the only factor in hair loss, as other environmental influences such as stress and age can also cause thinning or balding of the scalp. You can better manage your risk factors by understanding how genetics and hormones affect hair loss.

Stress and Hair Loss

Stress may be a significant contributing factor when it comes to hair loss. High amounts of stress have been linked to telogen effluvium, androgenic alopecia, and hereditary-pattern baldness, three different kinds of hair loss. Telogen effluvium is a condition that causes thinning or complete hair loss when the hair follicles enter the resting phase too soon due to a stressful event. Male pattern baldness, also known as androgenic alopecia, is a hereditary disorder that affects both men and women. It can be recognised by a typical pattern of hair loss and is brought on by hereditary or hormonal factors. The hair loss pattern and the history of other family members with a similar type typically determine hereditary-pattern baldness. While there are some differences between stress-induced and genetic hair loss, their effects on people are usually identical. It’s important to understand that genetics plays a role in hair loss and that other factors, such as stress, can also impact it.

Could Anemia Thin Your Tresses?

Anaemia could thin your tresses. However, it is not the only cause of baldness. Male pattern baldness is believed to be a hereditary gene passed down from either side of the family. This type of hair loss, also known as androgenetic alopecia, is caused by genetics rather than anaemia. Other forms of hair loss, such as alopecia areata or female pattern baldness, can be caused by hormonal changes or medical conditions unrelated to anaemia. The best way to determine if you are experiencing hair loss due to anaemia is to speak with your doctor about any symptoms and get tested for anaemia levels in your blood. If it turns out that you do have anaemia, treatments are available to help you restore your hair growth and prevent further thinning or balding.

Does Hair Loss Come From Your Mother’s Side of The Family?

Does hair loss come from your mother’s side of the family? It is certainly possible. The leading cause of baldness is believed to be a gene passed down from either the mother or father and male pattern baldness (androgenetic alopecia) is one of the most common forms of hair loss. Genetics, hormones, and ageing cause this type of hair loss, and research suggest that it could be inherited from either side of the family. Hair loss can also be caused by medical conditions such as alopecia areata or hormonal changes associated with menopause. Although baldness is often hereditary, other factors can contribute to thinning or balding. It’s essential to consult a doctor if you’re experiencing hair loss, as many medical associations ensure that content about causes and treatments for hair loss is accurate and current. If you believe your hair loss may come from your mother’s side of the family, speak to her about her experience with hair loss – it might give you some clues as to what you can expect.

Unhealthy Diets Can Result in Sudden Hair Loss

Unhealthy diets can result in sudden hair loss and baldness. Genetics plays a significant role in determining whether someone will experience hair loss, as the gene for male pattern baldness is passed down from either side of the family. Male pattern baldness, known as androgenetic alopecia, is characterised by thinning or balding on the scalp in balding areas. Other causes of hair loss include hormonal changes, such as menopause or medical conditions like Parkinson’s disease. Sixty-three genes associated with baldness have been identified through peer-reviewed studies conducted at academic research institutions. Genetic variation in the human androgen receptor gene is the primary determinant of common early-onset androgenetic alopecia. Treatment for hair loss varies depending on the cause and severity, but several options are available, including medications, laser therapy, and hair restoration surgery. It’s essential to ensure our content is accurate and current when it comes to information regarding hair loss and genetics to ensure that people suffering from hair loss receive appropriate treatment.


In conclusion, male pattern baldness is a genetically determined androgen-dependent trait, and understanding the genetics behind it is essential for helping to identify potential genetic targets for intervention. Several factors can contribute to hair loss, including those related to genetics and hormones. Hereditary hair loss, age, hormonal changes, and stress can all play a role in male pattern baldness. Therefore, it is essential to understand your DNA test results to understand the risk factors that may be at play. Reducing stress levels can also help down balding and maximise hair growth potential.
