Has anyone tried Pantodil Hair Ampoule?

Last weekend, I met up with some old high school friends I hadn't seen in ages. We took photos in the sunshine at a cafe with a beautiful outdoor terrace. Later, when I looked at the results, I was shocked by how bare my crown looked. I used to be so confident in my hair volume, but maybe it's just the passage of time that can't be helped. Every time I looked in the mirror, I sighed, and then I remembered a product a friend recommended: Pantodil Hair Ampoule. At first, I was skeptical, but now, determined to try something, I diligently apply it every evening after shampooing. Everyone around me raved about Pantodil Hair Ampoule. My scalp felt refreshed after using it, so I'm going to try it consistently. However, no matter how good the Pantodil Hair Ampoule is, I think I need to improve my diet and lifestyle habits to see a synergistic effect. So, I'm having a lot of trouble deciding. Has anyone else tried various solutions to their hair problems like I did? How do you usually take care of your scalp? Or, if you have any small tips that you've noticed while using this product like I did, please let me know.
