Hairline hair transplant?

I wonder if filling in the hairline might make the face look a little smaller.

I always feel a bit self-conscious when I tie my hair up or let my bangs fall forward ㅠㅠ

Is it possible to perform hairline restoration like hair transplantation for hair loss?

Because it's a partial area, how much the cost will be, as well as the durability and naturalness?

I'm curious about how detailed and specific it is.

I'm curious about the honest reviews from those who have received it ㅠㅠ

I'm also worried about whether there are any side effects,ㅠ.
