Please recommend a care cycle for Pantodil hair ampoules!!

My hair feels weak and seems to be falling out constantly, so I'm planning to get scalp care. I heard that using Pantodil ampoules strengthens the hair from the roots; is that true? Is the typical schedule for Pantodil treatments weekly?

I heard that having a healthy scalp prevents facial skin from sagging, so I'm planning to take really good care of it!! For those of you who have tried Pantodil, please let me know your real reviews on whether you saw any improvement in hair texture or volume!! I want to stock up while the benefits are good this month!!
