Impact of vitamin D on hair loss?

[ThinningB420]

Is there any impact on hair loss due to low vitamin D levels? My dermatologist said pray for low vitamin D levels before I had my blood work done. It turns out my blood work was fine except for low vitamin D levels. I had a 15 while the normal healthy range is 30-100. Is this a significant deficiency, and what impact does it really have on hair loss? I was told to take 2000 ICUs of vitamin D daily.

It's probably vitamin D3. Which comes from sunlight. Or you can just take it as a supplement.

Apparently most people in northern North America are deficient. I too had an extremely low level (I am in Toronto), and was also told to take 2000 IU a day (for 3 months, and then 1000 IU a day after that).

I highly doubt it has anything to do with your hair loss.
