It feels like my parting is getting wider... Could this be the start of hair loss?

Lately, every time I look in the mirror, it seems like my parting line is getting wider, and it's really bothering me...

It feels like my scalp is more visible than before, and my hair seems to have thinned out a little.

It seems like the amount of hair falling out when I shampoo or dry my hair has increased, but I'm confused whether this is normal shedding or early-stage hair loss.

In this case, is it possible that this is an early symptom of hair loss?

For those who have had a similar experience, I'm curious how you managed it.
