Hair loss treatments are effective, aren't they? I realized I really needed to get my scalp fixed.

My scalp was very hot and severely red, and eventually, the hair on the crown and sides of my head thinned out drastically. The itching is intense, and my hair feels greasy if I skip washing it for even a day, so it feels like my scalp's environment is completely ruined. I am anxious every day, fearing that I will lose hair uncontrollably if this continues. Even when I try to soothe it with scaling shampoos or tonics, the relief is only temporary, so I realized I ultimately need professional hair loss treatment to fix the scalp's condition first.

Has anyone received medical hair loss treatments for scalp regeneration or to reduce heat sensation? I am curious if a treatment program that combines inflammation care with hair root strengthening injections is effective. For those who have improved from cases like mine where seborrheic dermatitis progressed to hair loss, please share your criteria for choosing a clinic or your care routines.
