You see short hairs floating above your scalps, sprinkled throughout the length and think - oh no, is this breakage? Have I damaged my hair?
Probably not. Apply some simple hair logic. It's reckoned that we lose 50-100 hairs each day when we and our scalps are healthy. This varies - a few months after the end of summer we usually lose more hairs than in spring.
All things bring equal, it makes sense that 50-100 new hairs have begun to grow each day. And of course they're shorter than the rest of your hair.
Welcome those new little hairs. They're not broken or damaged, just exploring their new world.
