After applying this Pantodil Hair Ampoule, won't my hair become greasy or anything?

Hello, I am in my 30s and I am stressed out because I feel like my hair is falling out too much these days.
In particular, I feel like the crown area is getting a bit dry, so I'm looking into Pantodil Hair Ampoule.

What worries me the most is that after applying this product, my hair will become greasy or clumpy.
Is it absorbed well enough that I can apply it in the morning and go straight to work?

I'm curious to know if there are any people who have said that their hair has grown back or that their hair has become stronger after using the Pantodil Hair Ampoule.
If there are people who have tried it themselves, could you tell me what it feels like and what it smells like, it would be a great help in making a purchase.
