Hair loss concerns

When I was young, I often heard that I had a lot of hair, and I would go to the hair salon.

I often hear that my perm turns out well and that people around me also say the same.

Many people asked what kind of perm I got, but now that I'm getting older, my hair has thinned to about one-third. When I tie my hair up, I don't even have a proper head shape.

I'm really worried because it sticks together like a head soaked in rain.

I dyed my gray hair with a device, and my hair quality has become very poor.

My worries have doubled.

I'm using the hair loss shampoo, but I don't really notice any effects.

How does everyone manage hair loss?
