Has anyone tried the Pantodil Hair Ampoule? My scalp has been feeling a bit empty lately.

Hello. I've never really paid much attention to hair care, but I was shocked recently when I saw a picture a friend took of me. It was taken outdoors with the sun behind me, and the crown of my head looked much thinner than I'd expected. I'd often been told I had thick hair, but the saying "time is everything" really hit home, and I've suddenly become concerned. The area around my parting feels particularly bare, and I'm constantly concerned about it whenever I go out. Now, I feel like simple shampoo isn't enough, so I'm researching Pantodil Hair Ampoule for some nourishment. I've heard it's gentle and has good ingredients, so I'm considering trying it as a starter. I have an oily scalp, so I was worried it might be too greasy, but after reading reviews of Pantodil Hair Ampoule, many people say it leaves my hair feeling refreshed, which has me a little more reassured. I'm curious to know if anyone who has used Pantodil Hair Ampoule regularly has noticed any improvement in hair strength. Do you have any special tips or massage techniques for applying it? I'm acutely aware of the need for proper care these days, so I'm desperate for your valuable advice. Any suggestions are welcome, and I would appreciate it.
