My scalp is getting thin. How effective is the Pantodil scalp ampoule? ㅠㅠ

Maybe it's because I've been so stressed lately, but a handful of hair falls out every time I wash it. My parting looks so sparse that I'm seriously considering using hair fibers. I'm wondering if getting the Pantodil scalp ampoule treatment at Maypure really makes fine downy hairs or strong baby hairs sprout up. ! ㅠㅠ Seniors who have gotten hit, please leave lots of vivid, genuine reviews lol
