PRP with blunt cannula: I got a PRP injection into eyebrows for hair growth with a blunt cannula into subdermal layer. Thoughts?

it hurt a lot & there was a crunchy sound and he was very strong pushing the cannula through... Does that destroy anything in the skin or hair follicles ? Can you really stay in the subdermal layer with that blunt cannula ? I got the feeling he switched to the dermis (dermal layer) ...therefore he had to push so much... 2nd day post: its just a bit swollen and hurts just a bit ... Thank You so much ! Best, Carlo //
