As it says in the title, can a good diet help hair loss?
A diet is not really that important in regards to MPB. This is all about genetics and DHT blockers. Baldness depends on your genetics, if you have MPB genes you are gonna lose hair no matter how well you eat.
All being said, eating healty can only have a positive impact on your life.
Not if you have MPB bro, only the big 3 can help them but eating healthy can only help matters i guess.
No doubt a healthy diet can improve your lifestyle and possibly improve hair quality so of course it has major positive to lead a healthy lifestlye.
