I'm only 17 years old, yet I've recently noticed my hairline is starting to recede. My parents on both sides are in their mid 40's, and neither have them have shown any signs of hair loss. Is this even possible for someone my age? Should I be worried? Am I freaking over nothing? Is there anything I can do? Etc.
Thank you so much for the help.
Here are a few pictures.
