Do you all use scalp care ampoules to manage dry scalp in the winter?

The smell of chicken wafting from the elevator on my way home from work almost knocked me out... I resolved to diet for the end of the year, but it's really hard to resist. I barely managed to hold it in and showered, but now my scalp is itching like crazy. How do you all deal with the dryness on your crown of the head, which gets worse in the winter? My scalp feels cracked from the heater wind, so I tried a scalp care ampoule. It feels instantly refreshing, but I'm not sure how long it'll last. Now that I'm in my 40s, my hair is thinning, so I've heard using this scalp care ampoule is essential. Is there a special way to apply it? Is it okay to just apply it, or is it okay to just dab it on? I'm curious how you all manage it. Since I made a big purchase, I want to see the results! Do I need to massage it in for 10 minutes or can I just leave it on and go to bed? I'll be waiting for the answers from experts who know the answer!
