I'm worried about hair loss.

I used to think it wasn't my problem.

Lately, when I wake up and see the hair I lost, I looked around and found that there are various scalp care shampoos, and if it worsens further...

It seems like there are hair transplants, wigs, and tattoos.

Since hair transplants are known to be expensive per unit, please advise if you have any tips on how to manage and care for your hair before it worsens.
