Could Hairline Lowering Cause Hair Loss in Men?

What are the chances of some sort of balding from the hairline lowering procedure on men??? Im 27 years old and have not have any balding whatsoever yet and have no history of balding in my family. I am also Brazilian.

Any surgery like you describe (since it is stressful) could kick-start hair loss in men. With that being said, I generally recommend that the hairline lowering procedure (where a piece of forehead is removed and the hairline is brought down) is not a procedure for men. On the remote possibility that there is late onset balding in your case, you will be left with an obvious scar as the hairline recedes. If, on the other hand, you elect to lower the hairline with hair transplants, then there will be no loss of the leading edge of the hairline, as hair transplants are permanent.

The worst case scenario of having hair transplantation to restore or lower the hairline is that the hair behind it might recede, leaving a gap between the transplanted hairline and the hair behind it. In that worst case scenario, you can transplant the hair and fill in the gaps.
