Curly hair is a unique and beautiful hair type that has captivated people for generations. From tight coils to loose waves, curly hair comes in various textures and patterns, making each curl pattern unique. One question that often comes up when discussing curly hair is whether it is genetic. In other words, is curly hair something that you inherit from your parents, or is it solely determined by other factors? In this blog, we will delve into the topic of curly hair and genetics, exploring the science behind curly hair, the role of genetics in determining curl patterns, and other factors that can influence curly hair. So, let's unravel the mystery of whether curly hair is genetic.
Understanding Curly Hair
To fully comprehend the role of genetics in curly hair, it's essential to understand the structure of curly hair and how it differs from straight hair. Curly hair is characterized by its unique shape and structure, which differs from straight hair in several ways.
Curly hair has an oval or elliptical shape, which causes the hair shaft to curve or coil, resulting in curls or waves. This shape is due to the structure of the hair follicle, which is responsible for producing the hair shaft. In curly hair, the hair follicle is more asymmetrical, causing the hair shaft to grow in a curved or coiled pattern.
Additionally, curly hair has a higher level of porosity compared to straight hair. This means that curly hair tends to absorb and lose moisture more easily, which can affect its overall health, elasticity, and manageability.
Factors That Influence Curly Hair
While genetics play a significant role in determining the curl pattern of one's hair, other factors can also influence the appearance and behavior of curly hair. These factors include:
Ethnicity: Different ethnicities tend to have distinct hair textures and curl patterns. For example, individuals of African, Caribbean, or African American descent tend to have tightly coiled or kinky hair, while those of European or Asian descent may have looser curls or waves.
Hormones: Hormonal changes in the body, such as those that occur during puberty, pregnancy, or menopause, can affect the texture and curl pattern of the hair. Hormones can impact the shape and size of the hair follicle, which, in turn, can influence the curl pattern of the hair.
Environmental Factors: Environmental factors, such as humidity, heat, and climate, can significantly impact curly hair. High humidity can cause curly hair to frizz or expand, while dry environments can make it difficult to retain moisture in the hair, affecting its curl pattern.
Hair Care Practices: The way one cares for their hair, including styling, washing, and product usage, can affect the appearance and behavior of curly hair. Using harsh hair care products, heat styling tools, or improper brushing techniques can alter the curl pattern or damage the hair shaft.
Hair Length and Density: The length and density of the hair can also impact its curl pattern. Longer hair tends to have more weight, which can stretch out the curls and make them appear looser. On the other hand, shorter hair may have more springy curls due to the hair's reduced weight.
Genetics and Curly Hair
While other factors can influence curly hair, genetics play a significant role in determining one's curl pattern. The genetic makeup inherited from our parents can affect the shape and structure of the hair follicle, which, in turn, impacts the curl pattern of the hair.
Genes are the instructions that determine the physical characteristics of an individual, including hair type, color, and texture. The genetic information related to hair is stored in the DNA within the cells of the hair follicle.

Several genes have been identified to play a role in determining the curl pattern of the hair. One of the well-known genes associated with curly hair is the trichohyalin gene, which affects the keratin protein in the hair shaft and can influence the shape and texture of the curls. Another gene called the TCHH gene has been linked to the formation of the hair shaft and can impact the curl pattern.
However, it's important to note that curly hair is a complex trait, and multiple genes and genetic interactions can contribute to the overall curl pattern. It's not as simple as inheriting curly hair from one parent or another, but rather a combination of genetic factors from both parents.
Genetics can also determine whether an individual will have curly hair from birth or if their hair will change texture over time. For example, some individuals may be born with straight or wavy hair, but their hair may become curlier as they age due to changes in their genetic expression or hormonal fluctuations.
Furthermore, genetics can also affect other aspects of curly hair, such as its thickness, density, and porosity. These factors can impact how the hair behaves and how it responds to different hair care practices and environmental conditions.
It's also worth noting that curly hair can skip generations in families, meaning that even if one's parents or immediate family members do not have curly hair, it's still possible for an individual to have curly hair based on their genetic makeup.
Other Factors That Influence Curly Hair
While genetics play a significant role in determining curly hair, other factors can also influence its appearance and behavior. These factors include:
Hair Care Practices: How one cares for their curly hair can greatly impact its health, appearance, and curl pattern. Using gentle hair care products formulated for curly hair, avoiding harsh chemicals or heat styling tools, and adopting a proper hair care routine can help maintain and enhance the natural curl pattern.
Environmental Factors: Environmental factors such as humidity, heat, and climate can affect the behavior of curly hair. High humidity can cause frizz and shrinkage, while dry environments can make the hair more prone to breakage and dehydration.
Hair Manipulation: The way curly hair is styled, combed, or brushed can also influence its curl pattern. Aggressive brushing or combing, tight hairstyles, or constant manipulation of the hair can disrupt the curl pattern and cause hair to lose its natural shape.
Hormonal Changes: As mentioned earlier, hormonal changes in the body, such as those that occur during puberty, pregnancy, or menopause, can affect the texture and curl pattern of the hair. Hormones can impact the shape and size of the hair follicle, leading to changes in the curl pattern.
Diet and Nutrition: A healthy diet and proper nutrition can also impact the health and appearance of curly hair. Nutrients such as vitamins, minerals, and proteins are essential for maintaining strong and healthy hair, which can in turn affect the curl pattern.
In conclusion, curly hair is a unique and beautiful hair type that is determined by a combination of genetic factors and other influences such as environmental factors, hair care practices, hormonal changes, and diet. While genetics play a significant role in determining the curl pattern of the hair, it's important to understand that curly hair is a complex trait that can be influenced by multiple factors.
Understanding the role of genetics in curly hair can help individuals better understand their hair type and how to care for it. By adopting proper hair care practices, considering environmental factors, and understanding the impact of hormonal changes and diet on the hair, individuals with curly hair can maintain and enhance their natural curl pattern.
So, whether you were born with curly hair or your hair has changed texture over time, embracing and caring for your natural curls can help you embrace your unique hair type and enhance its beauty. With the right knowledge and care, curly hair can be a gorgeous and stunning asset that adds to your individuality and style.
While genetics may play a significant role in determining curly hair, it's important to remember that everyone's hair is unique and can be influenced by a variety of factors. It's not solely about inheriting curly hair from your parents, but also about understanding how to care for your curls and embrace their natural beauty.
