Today is 4 week post op. I had my HT mostly done to the front hair line to reinforce it. I've been reading a lot about "Shock Loss" and I think that's whats been happening. The entire site of the HT has lost existing hair. Enough to be quite noticable. I'm very concerned. Dr. Bernstien says this is all normal and that whetever is lost usually comes back. I was hoping for some first hand advise.
