There may not be any natural way to get curls then.

Fwiw beauty is subjective. When I traveled around, I learned that most people with curly hair and brown eyes wanted blonde hair and blue eyes. Then I met some blondes with blue eyes in the US that wanted curly hair with brown eyes. They sell certain creams in non white countries that make your skin look whiter while people in the US are spending hundreds of dollars going to tanning beds to look darker.

When I realized this fact, I just embraced my features. You can find ways to accentuate your natural features.
