My hair started to really thin when I was 40. These are things I personally did for myself that helped me regrow my hair and stop the hair loss.

I always had fine hair but my hair didn’t really start to thin out until I was 35 or so and at first it that was rather slowly and basically unnoticeable till I hit 40. Even then it was not too bad and I still could cover it up a bit. However, my hair got thinner and thinner & the good looking women I always attracted, somehow didn’t seem to be as attracted.
