Why are hair transplants so expensive?

[VeraJordan]

Hello everyone,
Most people have very healthy hair. There are also a few people with alopecia, although they are young, but their heads have lost a lot of hair, revealing bald patches, little hair. That makes them very insecure about their appearance, especially for women. To overcome that situation, many women have chosen hair transplant solutions. But indeed, I do not understand for what reason that hair transplants for women are so expensive?
Thanks everyone.
