Are the benefits of professional hair loss treatment certain?

Lately, my parting seems to be getting wider, and the amount of hair falling out every time I wash it has increased noticeably, which is really stressing me out. My scalp on the crown of my head feels like it is clearly visible, so I get self-conscious whenever I go out, and it has really lowered my confidence. Before it's too late, I plan to start professional hair loss treatment at a dermatology or scalp clinic.

There are various treatment methods such as injections, lasers, and medication prescriptions, but I am curious about the main advantages of hair loss treatment conducted at a clinic. Is there a definite difference in hair thickness or hair regrowth effects when combining dermatological hair loss treatment with home care alone? I would appreciate information from those with experience regarding the benefits of receiving professional treatment in the early stages and how long it typically takes to see results!
