Stress is a significant habit that can lead to early hair loss and as such you need to make sure that you relax regularly in order to prevent this from speeding up your baldness.
Baldness is very much genetic and while there are some things that you can do in order to prevent early baldness, it is unlikely that you can completely stem the tide if male pattern baldness runs in your family.
Make sure that you exercise outdoors as well, in sunlight preferably, in order to get healthy doses of vitamins D. Of course, there are alternative methods that you could use.
Vitamins such as iron, copper, calcium, zinc, and vitamins B 7 and B 12 should be incorporated.
Numerous different techniques can be incorporated in order to help, such as deep breathing exercises and meditation.
