Is Receding Just One Temple Peak Normal?

I have a question about temporal hair peak, my temporal hair peak in my left side has disappeared whereas the right side temporal hair peak is still ok, thus it makes an asymmetrical looks. It does not bother me since the temporal hair peak is not as important as baldness, however, I just want to know that does loss of temporal hair peak indicate the onset of hair loss on my scalp? And will my right side temporal hair peak follow the loss with my left side? Cheers

Your description of asymmetrical temple peaks are relatively common. It is one of many examples that humans are not perfectly symmetrical. It does not signify the onset of hair loss.
