Is hair transplantation expensive?

In the past, hair loss was considered degenerative, so people just had to live with it or wear wigs, but nowadays that's not the case.

They say hair loss treatment is also available and that hair transplants are performed, so I think it's really a good world to live in.

I'm not there yet, but seeing my hair thinning and falling out at this rate makes me think that someday I will experience stress due to hair loss. Then I would want to get a hair transplant, but I'm curious about the cost. If I knew in advance whether I could afford it, maybe I could save up more diligently...
