Will I be able to feel the effects of the hair loss treatment?

Hello. I work in an office, and I am concerned because the hair on the crown of my head seems to be thinning significantly lately.

It stresses me out every time I look in the mirror, and it keeps bothering me whenever I see my reflection on my way to work. I am not taking any medication yet. I am considering starting professional hair loss treatments first to ensure more effective management.

What I am most curious about is the actual tangible effects. Do treatments like mesotherapy or injections really help thicken hair or promote the growth of fine hairs? I am too busy with work to visit frequently, so I am wondering how many sessions are typically required to see noticeable results from hair loss treatments.

I would like to know if I can resume my daily life immediately after the hair loss procedure, and if proper care can yield results beyond just maintaining my current condition. I am hesitating because I worry that I might just end up spending money without seeing any difference, so I would appreciate honest reviews or advice from those who have already experienced this!
