I am curious if those who have received hair loss treatments were actually effective.

Lately, I have been losing more hair when washing it, and the top of my head seems thinner than before, so I am becoming increasingly worried.
I have consistently used shampoos and supplements, but I haven't noticed any significant changes, so now I am even looking into hair loss treatments.
There is so much information on the internet that I didn't know what to believe.
I am writing to inquire because I am most curious about honest reviews from those who have actually received it.

In particular, I would like to know how effective the hair loss treatment actually is.
How long does it take to feel changes after starting the procedure?
I am curious to hear about your experiences regarding whether you feel your hair getting thicker or if the amount of hair loss decreases first.
I know that it varies from person to person, but I would like to hear about the general process of improvement.

I am also curious about what the biggest advantage of hair loss treatment is.
Is there anything that is more helpful than just taking medication?
I would like to know if consistent care helps with maintenance as well.
Whether the procedure tends to take a long time,
I would also like to hear opinions from those who have experienced it regarding the degree of pain.

Above all, I am most curious about the satisfaction level of those who have actually received it.
Since the cost of hair loss treatment is not insignificant, I want to make a careful decision before starting.
I would like to hear your honest feedback on whether you were satisfied with the procedure or if you were disappointed that the changes were less than you expected.
If there are significant differences between hospitals, is there anything you absolutely must check during a consultation?
It would be really helpful if you could share this information as well.
