(Concern) My hair lacks strength.

As I get older, my hair quality has also declined. My hair is gradually losing strength, and I am shedding more during seasonal changes.

I'm trying not to dye or perm my hair often. Especially, the front part with the parting is falling out more. Maybe it's because I wash my hair frequently in the morning and evening? I'm also taking brewer's yeast, but I haven't noticed any effects yet ㅠ

Please recommend shampoos, treatments, or scalp massages that are good for hair loss.
