Yes — if both straight-haired parents are heterozygous (Ss).
S is dominant, so straight phenotype can be SS or Ss. Crossing Ss × Ss gives a Punnett square: 1 SS : 2 Ss : 1 ss. That yields a 25% chance of ss, which is curly. If either parent is SS (homozygous dominant), curly (ss) offspring cannot result.
To determine a parent’s genotype, you can test-cross it with a known ss individual: if any offspring are curly, the parent was Ss.
