Women’s hair loss

Around age 48, when my bangs reached about 50cm in length, I started to worry because it didn't seem long enough. Over the past five years, I noticed that the bottom of my hair is visible, and when I look from the front, I can see my scalp, which bothers me a lot. I have been doing scalp massages, but it doesn't seem to help. I don't know the cause. Could it be because I have many gray hairs and frequently dye my hair? Or am I starting to experience hair loss?
