Hair concerns, should I get a hair loss treatment?

I've never really had thick hair, but recently I've become increasingly worried because it seems like I'm losing a lot of hair overall. The crown of my head looks particularly sparse, and it's quite stressful because my scalp is so visible when I tie my hair up. Since I have curly hair, I used to get a perm once a month, but lately I'm hesitating to get the procedure done because I'm afraid of hair loss.

When I take photos, the top of my head looks thinner than I expected, which bothers me more. I've tried various shampoos and scalp care products, but I haven't noticed any significant changes. So, this time... hair loss treatment I am seriously considering getting it.

What I want to know is the actual extent to which hair loss treatments are effective in alleviating hair shedding and improving scalp health. I am also curious whether it is true that satisfaction is high when consistent care is followed according to the recommended sessions, and how long the effects last after the procedure.

Even for someone like me, who has thin hair and is concerned about hair loss on the crown of my head hair loss treatment I would like to hear opinions from those with actual experience regarding whether this is a suitable choice. I am leaving this question because I need information on actual satisfaction and effectiveness that cannot be determined from advertisements alone.
