Those who have tried Pantodil Hair Ampoule, how is the effect?

My hair has been falling out noticeably lately, so I'm trying to start taking care of it, and a friend recommended Pantodil Hair Ampoule.

The advertisements claim it's incredibly good for scalp nutrition, but I'm curious to hear from those who have actually used Pantodil Hair Ampoule for a long period of time. Specifically, I'd like to know if Pantodil Hair Ampoule actually helps with stress-related hair loss.

I'm curious about the non-sticky texture and whether the Pantodil Hair Ampoule causes hair to become greasy after use. Since it's a bit pricey, I'm posting this because I want to make a careful decision before purchasing the Pantodil Hair Ampoule.
