Has anyone tried using scalp care ampoules to combat static electricity and itchiness in the winter?

It's past 6 PM, and I'm so hungry I almost cried when I passed a chicken place on my way home from work... I've only been dieting for three days, but why is the smell of chicken so strong? ㅠㅠ I barely resisted the temptation, came home, and when I looked in the mirror, I had a bigger worry than hunger. Maybe it's because the weather suddenly got cold and dry, but my scalp kept getting itchy, and the static electricity was really bad whenever I brushed my hair. So I quickly searched the beauty community and bought a scalp care ampoule. Do you guys use these regularly? This is my first time using this, so I'm really curious to see if it works right away. Yesterday and today, I thoroughly applied this scalp care ampoule after shampooing, and it felt slightly cooling and less sticky than I expected. So, my first impression was a good one! However, the bottle is smaller than I thought, so I think I'll use it up quickly. Do you know of any other scalp care ampoules that are cost-effective or effective for soothing and moisturizing? Every winter, my scalp gets so dry and flaky. I'd love to know if anyone else suffers from the same problem as I do, and how you all overcome it! I know I have a lot of questions, but if you could share any skin care tips, I'd really appreciate it!
