I'm guessing by your genes.
No human "discovered" curly or straight hair. It is in our genes and is how God made us.
All of their children will have straight hair, as the father can only pass on the dominant straight hair allele. The children will inherit one straight hair allele from their father and one curly hair allele from their mother, but the dominant straight hair allele will mask the recessive curly hair allele.
If you have straight hair of curly hair. I think straight haris is dominant.
The shape of the hair follicle determines whether hair is straight or curly. A round hair follicle produces straight hair, while an oval or asymmetrical follicle produces curly hair. Additionally, genetics play a significant role in determining hair texture.
