I am so curious about the effects of the hair loss treatment.

I am considering hair loss treatment because of my thinning scalp every time I look in the mirror.
I am asking this question because I am very curious about the effectiveness of the hair loss treatment.

I feel that drug treatment alone has its limitations, so I am looking for various information in hopes of seeing the effects of hair loss treatments.

How long does it actually take after the procedure to feel the noticeable effects of the hair loss treatment?

I would like to know if it simply results in fine hairs growing back, or if the hair roots themselves become stronger, leading to significant overall effects from the hair loss treatment.

Given the significant cost, I would appreciate your advice on whether the hair loss treatment will yield guaranteed results relative to the investment, and if you have any recommended management methods.
