Can my tough hairdresser cause permanent damage to my hair?

My hairdresser was really tough , i felt my hair being pulled when he was using the scissors , he also kept scrubing my scalp hardly could that cause permenant hairloss , i also have thining hair & started exeriencing stage 1 of receding hairline so my hair usually falls fast , in the shower while shampooing i usually see like 25 hairs falling maybe there is more i could see but there is a side with more reced hairline than the other also i got some little dandruff too.
