Is there a specific hair loss treatment that helps with recovery in a short period of time? Does anyone know about such procedures?

Recently, I pushed my diet a bit too hard to lose weight, and while I did lose weight, I ended up losing all my hair along with it. My heart sinks every time I see a clogged drain after washing my hair, and three or four strands fall out just by running my fingers through it. I am frantically taking protein and biotin, but the hair that has already thinned and fallen out is recovering so slowly that I am looking into professional hair loss treatments.

Has anyone received hair loss treatments, such as nutrient injections or follicle regeneration lasers, for acute or telogen effluvium? I need realistic advice from those with experience on whether there are specific treatments to help restore hair roots quickly when they have weakened due to dieting, and how often and at what intervals I usually need treatment to return to my original hair density.
