Beer yeast shampoo for hair loss management

For hair loss management, I know that it's not good to be exposed to too much UV rays, and it's also recommended to have good airflow, dry hair well, and rinse thoroughly. The separate product I use is beer yeast shampoo. I apply the ampoule after drying my hair, spray it on, and massage it in for care. The beer yeast extract contains 790,000 ppm, which is said to help with hair loss management. I started using it because previous media suggested that beer yeast is good for hair care.
