Hello, I'm a genetics enthusiast with a passion for understanding how our DNA influences our physical traits. When it comes to hair texture, genetics play a significant role.
Hair texture, including whether it is curly, wavy, or straight, is largely determined by the shape of the hair follicle and the structure of the hair shaft, both of which are influenced by our genes. The specific genes that are most associated with hair curliness are still a subject of research, but it is known that multiple genes contribute to this trait.
One of the key genes that has been identified is the TRICHORHINOPHOSPHATE (TRIP) gene. Variations in this gene have been linked to differences in hair texture. Additionally, other genes are also believed to play a role, and it's the combination of these genetic variations that ultimately determines whether a person's hair is curly.
Environmental factors can also influence hair texture to some extent, but the underlying trait is primarily genetic. For example, hair can become curly due to environmental conditions like humidity, but if the genetic predisposition for straight hair is present, the hair will likely return to being straight when the environmental conditions change.
In summary, while there is still much to learn about the specific genetic mechanisms involved, it is clear that curly hair is indeed genetic.

Hair type is an interesting case of something called incomplete dominance. What this means is that with hair type, if you have one of each version of the gene, you get a mix of the two or wavy hair. So for hair type, CC gives curly, Cs gives wavy and ss gives straight hair.
