I am 25 years-old and had a hair transplant three months ago and all of my hair fell out that I had there before the transplant.
You developed shock loss after the surgery, a common event for young men. The prevention for this is the drug Finasteride which seems to work to prevent shock loss which can last almost a year after the surgery. Shock loss is an acceleration of the normal hair loss process and it is particularly dangerous for men in their 20s who have hair transplants.
