The scalp is a concern during dieting... Has anyone tried a scalp care ampoule?

It's already 12:07... It's midnight and quiet, but the winter wind howls outside the window. The room is warm with the heater on, but the low humidity makes me feel like my whole body is drying out. I'm on a diet, so I had a very light dinner. But at this hour, the savory smell of chicken wafting past my nose is driving me crazy. I'm staring at the mirror, trying to forget my hunger, and suddenly I wonder why my crown and hairline look so empty. It's great that my face is slimming down as I lose weight, but maybe it's a lack of nutrition or the dryness of winter. My hair doesn't look what it used to, and my heart sinks. I'm a worrier, so when I get anxious, I can't sleep. So, desperately, I recently bought a bottle of scalp care ampoule and started using it. After showering, I thoroughly dry my hair with lukewarm air, then apply these scalp care ampoules, one by one, focusing on the crown and sides of my head. At first, I doubted whether they would actually absorb, but I rely on the coolness of the cool formula and continue to apply them diligently every night. Besides these scalp care ampoules, are there any other lifestyle habits I should follow? The weather is already cold and my heart is heavy during the holiday season, and I'm terrified of losing my precious hair. I'm curious to know if anyone else experiences sensitive scalps or flaky skin like I do in the winter. I'm trying to resist the temptation of chicken and go to bed early tonight, but I hope these habits bear fruit and my efforts are worth it. Good night, everyone, and take care of your scalp health...
