Since it's winter, I'm so thirsty, so I bought a scalp care ampoule... What do you all think?

After work, I showered and came out, and it was already past 8:30 PM. It's been so cold and dry lately, my face and entire body are feeling parched. I figured it couldn't get any better, so I've been trying to drink two liters of water a day, but it seems my scalp is the real problem. My hair feels tingly around my part, and the static electricity, perhaps from the heater, has gotten worse. So, I decided to buy my first scalp care ampoule. Thinking back, I feel like I've been neglecting my scalp health while pouring all my effort into my face with ampoules and creams. I'm feeling a little guilty. I'm hoping this scalp care ampoule will work for me. I applied it for the first time today and it definitely has a cooling sensation and has helped alleviate some of my dryness, which piques my curiosity. Many of my friends also experience stress from dead skin cells in the winter, so if it's really effective, I'd love to recommend it. Are any beauty experts out there who have tried scalp care ampoules? It might be a hassle to get into the habit of taking care of it at first, but since I've started, I want to keep it up along with the habit of drinking water and stay hydrated this winter!
