How does the Pantodil Hair Ampoule feel? Has anyone tried it?

My hair keeps falling out and getting thinner, so I'm looking into trying a scalp care ampoule.

I've heard that the Pantodil Hair Ampoule is easy to use because it's a roll-on type, and that it's good for preventing hair loss. Has anyone tried it? If so, please share your experience with the Pantodil Hair Ampoule.

I'm curious if my hair will feel greasy or sticky after application. Since I have a very oily scalp, the first thing I consider when buying hair products is whether or not they make my hair greasy. I also want a hair ampoule that can take care of the oiliness of my scalp.

I would like to know if it prevents hair loss and controls sebum so that the scalp doesn't get oily. I want to know if the Gal Pantodil Hair Ampoule doesn't make my hair greasy after use and if the scalp stays refreshed.
