I'm curious about hair loss treatment.

Like a female model selling wigs on home shopping, my front and top hair are sparse.

I also tried partial wigs, but it seems that you need some hair volume in the front for the clips to stay securely in place.

The amount of hair loss is so significant that the stress is quite overwhelming.

I want to receive treatment but I am unsure which treatment would be best. I am an elderly person, so I understand, but my stress is very severe, and I want to undergo treatment for my own satisfaction. What is the most effective treatment?
