Please recommend a hair essence that helps with hair loss management!

I am worried because my hair is getting thinner.
Lately, I feel like I'm losing more hair and it's getting thinner overall.
I am looking for a hair essence that might be helpful for hair loss management.
Which hair essence should I use?
And which ingredients help prevent hair loss and improve scalp health?
It would be great if you could also let me know the price range.
