What are good ways to prevent hair loss?

My biggest complex is that I have too few friends.

If you really try to grasp it with your hand, it's less than a quarter of your friend's head size. Every time, I really struggle with it...

I've been hearing teasing since long ago, like "You're going to go bald, what will you do?" and it's really bothering me.

Now that I’ve had a baby, I started losing hair more quickly, and now the older I get, the faster it falls out.

50 cases a day? That's considered normal, but I am processing several times that amount.

Every time I clean up the thick hair that accumulates after washing my hair, it hurts my heart so much. How do others like me manage this situation?ㅠㅠ
