How do you take care of your scalp at home?

I've always seen people around me take care of their scalps, but I never really empathized with them. This winter, I noticed my hair falling out in clumps every time I moved, almost like I was shedding hair. That's when I suddenly became interested in scalp home care. I used to just pick a shampoo with a nice scent, but now I use a shampoo specifically for hair loss, use a treatment, and apply scalp nutrients. I also turned a deaf ear to the advice from experts about not drying my hair with too much hot air, but now I always use lukewarm air for the first half of my haircut, and only use hot air at the end to make sure it's all done. Even after doing this, my hair still falls out. ㅠ

Those who have seen results with scalp home care, please give me some tips on what kind of scalp home care you do.
