I'm worried because I'm losing a lot of hair.

Hello. I am older and have a lot of hair loss in my family, so I have been worried about it. Recently, I have been losing a noticeably large amount of hair. I have tried many shampoos that are said to be good for hair loss, but I am not sure about their effectiveness. I do eat food, but it doesn't seem to have much effect. If you know of any methods that have worked for you, please let me know.
