Why do I have long curly hairs on my calves?

I’m an Asian girl and I know that most female Asians don’t really have a lot of body hair. I only have really fine thin body hair that is almost unnoticeable (unless you really look closely) on my arms, legs, belly and breasts so I never really felt the need to shave or remove them. However, what bothers me most is body hair on my calves. I never shaved them my whole life yet why are they long and curly?

A lot of people advice me to not shave it because it will just worsen (based on their experience) and once you deal with it, you will have to go through it your whole life and laser treatments are way too expensive.
