Hair loss and vitamin D

I am a 19 year old guy from Danemark. I have had a passion for having that metalhead looking long hair and I did grow it out quite a bit. At about 18 I went through a lot of emotional stress and had a very bad diet (sugars/carbs/not enough calories). At about this time I have noticed some extra hair in the shower so I didn't think much of it. Fast forward a few months and I started seeing more and more day by day. It got to a point that if I brushed my hair i would remain with almost a mini rug of hair on the hairbrush. I got recommended to watch your videos by a friend and saw your video about vitamin D and hair loss. I started taking about 20,000 IUs per day for about a month straight and this week i started to notice only broken hairs in the shower, no full sized ones. Then yesterday and today i didn't notice any hairs and not even on the hair brush. Your advice literally saved my hair and life since I became extremely depressed and closed up because of the fear of becoming bald. I want to tell you that you have done for me with this advice more than any doctor ever could've done. I see you as a hero for this, Thank you from all my heart!
