Pantodil Hair Ampoule: Will this help with volume at the crown of the head?

Lately, I've been going out to take photos of my hair with friends often, and every time I take a photo from above, I'm shocked by how bare my crown looks. I've never had to worry about my hair thinning, but I've been so stressed that my parting has been getting wider. So, I was looking for a new shampoo and something to try, and I came across some pretty good reviews of the Pantodil Hair Ampoule, which piqued my interest. My scalp is sensitive, so I'm worried it might be too irritating or irritating. How does the Pantodil Hair Ampoule feel? I'm drawn to the idea that it absorbs without stickiness, but I'd love to hear some real feedback from people who have actually tried it. Will applying it diligently every evening really help my hair thicken again? If you have any other effective routines, please share them with us.
