My hair is thinning and falling out a lotㅠ Can you recommend some supplements?

I am currently in my late 40s.

As I entered my 40s, my hair started to thin.

Since two years ago, when I started losing a lot of weight by dieting

My hair loss has also worsened.

Every time I wash and dry my hair

It's stressful because I'm losing a handful at a time.

I'm curious about supplements that are effective in preventing hair loss.

I'm always surprised when my younger sibling asks where all that hair went.ㅠ

Please recommend supplements that are effective in preventing hair loss.
