Male pattern Hair fall. It aggravates?

Suffering from hairfall since I was 21 years old and it's been 7 years now, consulted many doctors and used many medicines (minoxidil..), shampoos(anti dandruff..), lotions(no skurf, ultiderm, anaboom) for the same over the years. Now the dandruff problem subsided to some extent but the hairfall and secretion of white, greasy sebum for every 2 days has not gone yet. Never bothered about taking any nutritional foods for all these years for my hair health but for the past six months been taking sunflower, almonds, pumpkin, watermelon and flax seeds every day in the morning and no big change from this. I started taking whey protein for the past 1 week thinking the fall is becoz of protein deficiency. Will this be able to stop hairfall and start hair regrowth? Already hairs are miniaturized and front scalp became visible😞. Some say whey protein lessens hairfall and some say it aggravates? Respected doctor your precious advice is appreciated.
