Question) Will it be effective if I just switch my hair loss shampoo?

Lately, it bothers me because the drain is full of hair every time I wash my hair. My hair seems thinner than before, and I'm worried because the top of my head looks a bit sparse.

People around me are suggesting I try hair loss shampoo. Could simply changing my shampoo really help? I am considering switching shampoos first before visiting a doctor. There are so many types that I'm not sure which ingredients or product to choose.

Has anyone actually seen a reduction in hair loss or seen positive results after using hair loss shampoo? I am also curious if you managed this alongside medical treatment or nutritional supplements. Please share any product recommendations, care methods, or personal experiences you may have. 😊
