The probability of a fair coin coming up "heads" on any given flip is always 50%, regardless of previous outcomes. Each flip is independent of the others, so the previous streak of "heads" has no impact on the next flip. Therefore, the probability of the coin coming up "heads" on the next flip is still 50%.
