Male Baldness Info

27, earlier i have been using commercial brands of shampoos regularly, suffered from severe stress and chronic depression throughout the early 20′s, and ate junk now and then. I have made major corrections to my lifestyle, now i don’t require any medication for depression (cured a year ago), stopped applying any shampoo except natural herb extracts, turned vegan and strictly obeying the rules of complete nutrition.
but, probably due to my earlier pathetic lifestyle i suffer from early hair fall/baldness . to be very clear, it is ‘Male Pattern Type 2′ baldness. My maternal grandpa is partially bald (he didn’t have it that early), paternal side it is seen only after 50′s.
how can i prevent farther hair loss. do ladies in late teens and 20′s find partial baldness (see link) unattractive over a good athletic physique, education and height?
p.s. shaving scalp looks disgusting on me.

In January my hair started to thin out all over, and hair was falling out all more than usual. Then that slowed down, but I noticed that my hair line at the front and sides is receding.
Is there anything I could be eating or doing that is causing male pattern baldness to affect me early?
