Hey there! I experienced shock loss after my hair transplant, and let me tell you, it can be a bit alarming but it's totally normal. In my case, it lasted for about 2-3 months post-surgery, but everyone is different. The new transplanted hair will eventually grow back, so try not to stress too much about it.
Just make sure to follow your doctor's post-op care instructions, be patient, and give it time. It can be frustrating, but the end results are worth it. Hang in there!
