Hair is an essential aspect of our appearance and personal style. It can be long, short, straight, curly, blond, brown, black, or red. But have you ever wondered where your hair genes come from? Are they inherited from your mother or father? In this blog post, we will explore this intriguing question and provide you with detailed insights into the genetics of hair.

The Genetics of Hair

Hair is composed of a protein called keratin. This protein is produced by specialized cells called keratinocytes, which are found in the hair follicles. The hair follicle is a small, sac-like structure located in the skin. Each hair follicle has its blood supply and is connected to muscles that allow the hair to stand up straight.

The genetic makeup of an individual plays a vital role in determining the characteristics of their hair. Hair color, texture, and thickness are all influenced by the genes we inherit from our parents. However, it is not a straightforward process, and there are several factors involved in determining our hair genes.

Hair Genes from Mother

One common belief is that hair genes are inherited from the mother. This idea has been perpetuated by old wives’ tales and folklore. However, scientific research has shown that this is not entirely accurate. While we do inherit some hair genes from our mother, we also receive genes from our father.

One of the genes that determine hair color is called the MC1R gene. This gene is responsible for producing the pigment melanin, which gives hair its color. It has been found that variations in the MC1R gene are associated with different hair colors, such as red and blonde. This gene is located on chromosome 16, which is inherited from both parents.

Hair Genes from Father

Another gene that plays a significant role in determining hair genes is the androgen receptor gene (AR). This gene is located on the X chromosome and is responsible for regulating the growth and development of hair follicles. Since males inherit their X chromosome from their mother, they can inherit hair genes from their maternal grandmother.

Moreover, a recent study has found that the gene EDAR (ectodysplasin A receptor) is responsible for determining hair thickness and density. This gene is located on chromosome 2 and is inherited from both parents. Thus, hair genes are not solely inherited from the mother, and it is a combination of genes from both parents that determines hair characteristics.

Other Factors Affecting Hair Genes

Apart from genetics, several other factors can influence hair genes. These factors include hormones, age, and environmental factors. For example, the hormone dihydrotestosterone (DHT) is known to shrink hair follicles, leading to hair loss. This hormone is produced from testosterone, which is more abundant in males than females. Thus, males are more likely to experience hair loss than females.

Age is another factor that can affect hair genes. As we age, our hair follicles shrink, leading to thinner hair. Moreover, environmental factors such as UV radiation, pollution, and harsh chemicals can also affect hair genes. Excessive exposure to these factors can lead to hair damage, hair loss, and changes in hair texture and color.


In conclusion, hair genes are a complex combination of inherited genes from both parents, with several other factors such as hormones, age, and environmental factors playing a role in determining hair characteristics. While the idea that hair genes are inherited solely from the mother is a myth, it is true that certain genes are more dominant and can have a more significant impact on hair genes. By understanding the genetics of hair, we can gain a better understanding of the characteristics of our hair and how to care for it properly.
