Is it too early to experience shock loss? 3 weeks post-op.

To be specific, this question refers to my exsisting hair, not my grafts. 30 yr old male. NW 2.5. On propecia 5 yrs, no further loss or thinning the entire time. Just underwent a small 850 FUE. Majority of grafts placed in area with no hair Since the HT my hairline started thinning quickly over the last week. Not to be dramatic but I’m definitely loosing native hair. Odd thing is they’re thick hairs, not thin. All have white caps In your experience does this reverse? Going to the doc soon.
