I am curious about the effectiveness of hair loss treatments.

Phew...
My hair started falling out significantly, and recently, my scalp on the crown of my head is clearly visible, causing me immense worry. I have tried changing shampoos and taking supplements, but they haven't had much effect, so I am considering medical treatment. I have heard about various methods like follicular injections and exosomes, and I would like to know how effective these hair loss treatments actually are. If I start treatment in the early stages, can I see more noticeable results? I have heard that the effectiveness of treatments varies greatly depending on individual constitution and the speed of hair loss progression; I am curious how long it typically takes to see fine hairs grow or hair thicken after starting treatment. I am also concerned about potential side effects, such as hair falling out again if I stop the treatment midway. I would appreciate it if you could share your criteria for choosing the right type of treatment or reviews from those who have seen satisfactory results from hair loss treatments.
