Are there any good home care methods for hair volume?

Hello! Lately, I've been losing a lot of hair and it seems to be weakening significantly, which is incredibly concerning. Every time I look in the mirror, I see my parting and crown getting wider, which stresses me out. It's time to start taking better care of my hair.

Before going to the hospital, I'm researching home remedies to prevent hair loss. Some say regularly eating black foods like black beans is essential, while others recommend brewer's yeast supplements, which are said to help strengthen hair roots.

I'm interested in pantothenic acid, a component that directly affects hair structure, as it's said to be effective. I'm curious to hear from those who have actually tried these supplements or foods about their effects. Or, have you tried hair loss treatments or found that your own unique shampooing or scalp massage routines have helped?

​I would really appreciate it if you could share any valuable tips, even the smallest ones, in the comments.
