I'm curious about reviews from people who have received hair loss treatments!

I'm really stressed about hair loss because of my family history.
I've tried taking medicine and changing shampoos, but I haven't seen dramatic results, so
In the end, I wondered if a hair loss treatment was the answer.

I searched a lot, but there were too many promotional posts,
It's hard to tell which ones are genuine reviews.

Has anyone tried hair loss treatments (scalp tattooing, injections, etc.)?
What hair loss treatment you had,
How long is the pain or recovery period,
And I'm also curious about the most important thing: the cost.

I would like to know if the satisfaction level is really high and if there were any side effects.
I want to hear genuine reviews from people who have actually experienced it, not promotional reviews.

It would be a huge help if you could let me know whether you recommend it or not.
