Is It Normal to Have Weak Hairline Corners?

I am a 21 year old male. When I pull the hair at the corners (above the temples) I can lose 2 or 3 hairs at a time. The hairs here seem to fall out much easier compared to the rest but is this just normal?

It’s not necessarily “normal” for the hairline corners to be weaker than the rest of the hairline, but it could be due to the maturation of your hairline or early balding. Or it could be something as simple as styling product (hair spray, gel) in your hair that is trapping the hairs going through the regular growth cycle from falling out during your daily activities.
